YesVodafone thought that the response included wrong statements.
No architecture changes are required to enable EMDSDP.
BT: do we need to change anything to expose capabilities to a higher layer?
Vodafone: BEST is just user data, transparent at this point. You can see from the Attach that is a BEST service.
This LS had to be taken offline for further consideration from Vodafone.
Huawei commented that there was no concerns and no response was needed.

6.3 | ETSI SAGE | S3‑171050 | Support of 256-bit Keys and Algorithms in 5G | AT&T, InterDigital, MITRE | discussion | Decision | Yes |
YesDocomo: it makes sense when we want to increase the security of the overall system. The kind of attacks with quantum computers require a large number of resources. This large number of resources could attack anything really. Does this justify the investment for the overall security of the system?
AT&T found this justified.
Gemalto supported the creation of a WID/SID to have longer keys for the algorithms.
Docomo commented that there is more than extending the radio interface to 256 bits. All authentication solutions would need to be reevaluated. There's a lot of additional work.
Vodafone: how does this interact with the SAGE work?
Interdigital,, Gemalto supported AT&T's proposal for the work item. BT would support depending on the scope.
The Chair commented that there are more questions to be answered before starting the work. Starting now would impact the work on the phae one of 5G.
Qualcomm: we made a decision to use 128bits for the phase one. This can wait for phase 2.
Gemalto: do we need to tell SAGE that we won’t include QSC in phase one?
AT&T: I'm ok with not using 256bits in phase one, but SAGE should start the work soon so we have an answer when SA3 tackles this issue.
Interdigital: we should tell SAGE when to start.
Nokia: we are happy with 128 bits in phase one (specified by mid 2018).We don’t need longer keys algorithms by mid 2018. we might need them after that.

S3‑171362 | Initiation of authentication | Nokia | pCR | Yes |
YesSome concerns on the editor's note and its links with the privacy work.
Nokia: The Home network determines what authentication method to use.
Qualcomm: better rename EPS AKA* since we are creating a new protocol and may not have to be related to the one that is in the TR.
Ericsson: we discourage MME to handle more than one authentication vector, which is not here.
Nokia: it's a recommendation. Some operators would like to have batches of authentication vectors to be used in case of outage of the HPLMN.
Docomo: roaming in a malicious network then coming back to the trusted network is a confusing use case.
Deutsche Telekom: if we allow this, we have to deal with the consequences. This can lead to greater complexity.
Vodafone confirmed that the batches of authentication vectors are a useful tool for operators.
An editor's note and some text revisions were done in order to address all comments.

Vodafone didn’t favour the original .
Ericsson was in favour of this solution.
Gemalto commented that there is no requirement for support of legacy USIM.
Nokia: It shall be possible to compute this in the ME.
Oberthur: SA1 defines new requirements, if there are not new requirements the old ones are applicable. Keep it as it is.
Docomo: we need to make sure that the serving network name is something that we can use.
KPN had a slight preference for Vodafone's solution, as Huawei.

Deutsche Telekom: Note 1 in 7.1.1 should go away. Also, are we changing the SA acronym of AMF to avoid misunerstanding with our AMF?
Nokia: we add a note everytime that this can be confusing.
As per comments from BT the note was agreed to be reworded.
ORANGE: in TS 33.210 implementation of IPSEC was optional. Is it the same case in 5G core network?Ericsson preferred to keep it optional to implement. Telia Sonera, China Mobile and Deutsche Telekom had the same thought.
BT: we have a different concept of implementation. It's about turning it on or off.
It was agreed in 7.1.1 to add an editor's note on the management plane as suggested by Deutsche Telekom.
ORANGE: mandatory use of IPSEC is FFS. An editor's note was added to that effect.
MCC reminded that a better standardization term for "mandatory to implement and optional to use" was "shall be supported".

YesDocomo commented that the CS fallback/redirection to 2G wasn't the way. 360 and Huawei supported this.
Your first reject it and then redirect it to 2G and registers into the CS fallback. Better to fix the problem of having a call being sent over 3G even if we don’t want it in 2G.CS fallback call that we don’t want to have in 2G. It doesn’t matter if we want the authentication call before or not.
Nokia: distinguish between idle mode and terminating call. This attack doesn’t have to be with the CSFB, it's a more general attack. It's not about voice calls but forcing the UE not to go to an available 4G network.
Docomo: why is it an issue if we go to 2G? 2G is not so well protected. If there is an incoming call, yoCSFB and any type attack that will force the UE to be in 2G to receive this call will be bad.
Ericsson and BT agreed with Docomo. BT commented that a long term solution was needed.
Ericsson: why is RAN2 working on this if this a SA3 issue?
Nokia: this problem has been lingering since quite a long time. They copied us a few meetings back in a LS asking for feedback that we didn’t provide. It's not a 2G issue.
Docomo: the UE needs to be aware that this is something that happens in a 2G network.it should reject unprotected redirections.
The Chair commented that there is a bigger problem that we already knew. Can we solve such problem? With offline discussions, are companies aware of a bigger problem or not? Is there hope for a solution for this problem?

Ericsson: we need to address it if it is in the SA2 TS.
Vodafone: this refers to something that doesn’t belong to phase one,as we defined in a table in December. Huawei replied that this is not in that table.

YesQualcomm commented that option 2 is better, in order to minimise the impact on the UE. The NAS message should be kept the same.
Vodafone: option 2 protects the identities more than option 1.This should be added in the response to the LS.
Ericsson: the privacy solution is handled separately and it will be similar for both options. We support option one, achieving an architecture that is agnostic to the access.
Nokia: privacy concerns are the same for both options, the parameters are the same. We agree with Ericsson.
BT preferred option one because it was simpler for them.
Huawei and Intel went for option one.Intel commented that the first option was simpler to implement for CT1.
Huawei: if we have a privacy solution for option one equal to what we have in LTE, it's fine. 3GPP and non-3GPP accesses should have the same privacy protection.

Qualcomm: it’s more appropiate to look at this from the access and core network point of view, a separate study item would be required.
Nokia: is this relevant to the other 5G work we are doing? I think it isn't.
Nokia: it's about inter operator links. Sprint disagreed.
Docomo: Who authorizes the middleboxes to be there? It's premature before seeing protocols that can support this.
NCSC: hop by hop doesn’t have an issue. Security across domains is the key issue here and needs to be recorded.
Vodafone: at application level, is the middle box for them as well?
Home Office: the intention is that it is transparent for them.

Ericsson doubted whether the first question was needed. Handover will be studied but this contribution depends on other contributions that need to be agreed as well. They depend on the strcuture of the TR.
Qualcomm: why do we need this question for the study?Of course we need to study it in phase one,it's obvious.

Qualcomm: UP or CP attacks?
KPN: we have a key issue referring to the signalling.
Ericsson: already discussed but not agreed. Not appropiate to have a mechanism to detect bad behaving User Equipments.
Juniper Networks: DoS attacks is a huge topic. We need to narrow it down.
KPN: we have tdoc 386 with a more detailed approach on DoS attacks.

YesQualcomm: why not Rel-99 USIM?
Nokia: Rel-99 USIMs can be used for LTE access. This is not correct.
Docomo: From Rel-99 to Rel-8, there is a new separation bit, so the USIMs are different.
Oberthur: there are other non security features that differ Rel-99 and Rel-8 SIMs. The first question doesn't work, you need to update the card.It will never attach to 5G.
Deutsche Telekom: then ,the answer is no.
Oberthur: 5G authentication will never happen.
KPN: so we all get rid of all SIM cards in the World? What happens to my customers?
Oberthur: you can send new SIMs or update them.
TIM: operators will not throw milllions of SIMs away because of 5G. This wasn't defined in SA1.
Vodafone agreed with the question one.
ORANGE: this is valid for legacy SIMs.
TIM: this is a generic issue, not privacy.
TIM: if we have any doubt these requirements, we need to ask SA1.
ORANGE: we need to study technically this, not for business reasons. SA1 cannot decide that.
Gemalto supported ORANGE. This is a security group, we need to study if there is a security issue and we don’t know the conclusions yet.
G&D supported ORANGE's position. We need to consider the USIM evolution.
Deutsche Telekom and Telia Sonera supported ORANGE's proposal as well.
Gemalto: if we answer no to the questions, it doesn’t mean that we have to replace all USIMs.
Qualcomm supported ORANGE.
TIM objected to this contribution.
The Chair asked if this question blocked the work. It didn’t seem to be the case. He also pointed out that the question needed some clarification.
Nokia suggested to discuss this in a conference call.
BT commented that the impact on the UICC appears on the CR cover, so this can be discussed further depending on the technical issue.
The Chair commented that there is no restric rule for that and that it was better to reach an agreement beforehand in a conference call.
It was decided to have a conference call to clarify this contribution: questions on the use of legacy USIMs.

Vodafone: it isn't clear how to integrate this document into the TR.
Huawei: evaluation parts can be merged into the evaluation. The Chair replied that the best option give the lack of time would be to add an additional section for this document.

YesHuawei queried about the emergency calls.
Vodafone: Protected identity will impact emergency calls? This is an open issue.
BT: Non-3GPP accesses are in scope? E.g. using MAC addresses.
Vodafone: it’s still the IMSI for these kind of accesses.
BT: in WLAN there is a solution proposed by Apple, for example.
Interdigital: what are we trying to protect here? The IMSI?
Nokia: Subscription permanent identifier is what we try to protect here.
Huawei: it's allowed without subscriptions.
Vodafone: most countries forbid this, without subscription.
ORANGE: format of the subscription identifier is not defined in SA3.
Interdigital: in the TR we have a subscription identifier definition. It's not clear what we want to protect here.
ORANGE: the definition is for us alone, not for the overall 3GPP. SA2 is working on the subsucription identifier.
Ericsson: is the complete identifier protected? That's an issue as well.
On the emergency call part, Vodafone preferred "long term" over "permanent subscription identifier".Nokia replied that that would be a different key issue.

YesVodafone: wording is not correct ("significant hassles, last resort").
Second and third bullets were decided to be removed.
AT&T: according to SA plenary, there is a phase going to an existing EPC core whereas a "1.5" phase it goes to the 5G core.
The Chair confirmed that the understanding of "phase one" for SA3 is the one with 5G core.
Interidigital: hard to answer the question when we don’t know what to protect.
ORANGE: there are no contributions that address this issue.
Qualcomm wanted to have HN pseudonym as possible solution in E72A2.
ORANGE agreed with the answer no for that question. This was conceded by Qualcomm.
Huawei disagreed with E72C2, but as it was the same discussion as the show of hands, the group procceeded with the "no".
For E72D2, Huawei also disagreed. They proposed to have options for the privacy solution but ORANGE rejected this categorically. It was decided to agree with this one as well.
AT&T: PKI management; there automated procedures for millions of them. There's no such complexity of PKIs.

Telecom Italia: One publick key is easier to trust than multiple keys. It is a question of simplicity. There are a lot of certification authorities, certificates and so on. This was agreed by Nokia.
Vodafone: the issue is the management of the master key. What happens if it is compromised, how fast we can change it?That's our concern.

S3‑171301 | Question to slice identifier protection - was 767-204 | Nokia | pCR | Decision | Yes |
YesORANGE: the key issue is not about correlation of the slice id and the subscription id. Qualcomm agreed.
Nokia: the question is here because there was a discussion in the Busan adhoc and this is still an open issue.
Vodafone: No difference with the situation of having two base statiion with two network ids.
Vodafone: Why the extra protection of the NSSAI if we have privacy protection for the subscriber already?
Interidigital: we don’t need it.
It all was reduced to the question of the need of the extra protection for NSSAI. It was commented that the issue was more about confidentiality protection.
Vodafone: It's purely about slicing, not the privacy.
BT: you can identify the customer by the slice he's using, so Vodafone is wrong.

T-Mobile: this means no confidentiality protection in phase one.
ORANGE: not crutial for phase one.
Vodafone: capability yes.
Ericsson: not in phase one.
BT: not on phase one.
NEC: wait for SA2 procedures to finish this discussion.
Nokia: they are waiting for us.
Huawei: not for phase one.
Docomo: not for the initial registration but for the subsequent use of the slice. ORANGE and NEC were fine with this.
ORANGE: we need an answer for this meeting.
ORANGE: we say no and we work more on this when discuss the solution. Ericsson agreed, but some companies disagreed.
The Chair proposed as suggested by ORANGE: NSSAI shall be confidentiality protected whenever NAS confidentiality protection is enabled.
This was agreed.
Vodafone objected to the answer of this question being agreed in this meeting as many issues have been identified that need further thought before concluding on this interim agreement

S3‑171367 | Comments on S3-171144, Privacy aspects of MCC/MNC in IMSI | InterDigital, Inc., AT&T | discussion | Decision | Yes |
YesVodafone: even if I give you a random number I can guess your identity by identifying other factos like the time you turn on, or the places you appear, etc.. There's no such thing as real privacy.
Ericsson: Encrypting MSIDN it will be more complex to track someone.
T-Mobile: IMSI catcher needs close proximity and knowledge of the user.
Interdigital: hability to know the information by catching ovber the air is the real issue.
Deutsche Telekom: don’t forget that these are options for the operators and that in some countries they will not be allowed to use it. If we raise the bar too high and design an overly complex solution, we take the risk that it will not be used at all. Docomo supported this; it needs to be taken into consideration.
No apparent agreement between companies since their positions were quite fixed.

YesQualcomm: there may be other subscription identifiers rather than the IMSI, according to SA2.
The Chair asked: shall the routing information be hidden at the air interface (question in 299)?
Interidigital: preserving network policy should be optional (yes/maybe for the above question).
The Chair proposed a show of hands:
Show of hands per company for question in 299; who supports the response "no" (privacy protected)?
Vodafone,KPN,ORANGE,Oberthur,Juniper,Intel,Ericsson,Nokia,LG,Deutsche Telekom, Docomo,IPCom,NEC,Qualcomm,UK government, US department of commerce, China Mobile.
Same question, yes privacy protection:
AT&T, TIM, Interdigital, BT,360,Huawei, Neul Limited
Motorola Solutions abstained.
The Chair commented that this could go to a technical vote for the next meeting if there was no agreement.
AT&T proposed to go on with the "no" response so as not to waste time, Interdigital agreed.
The Chair asked the group if it was OK to procceed with "no" as the response to 299. There was no opposition and the document was approved.

YesBT: a lot of work will be done somewhere else.We will support the SID.
TIM: the attacker will be able to find the new key after being compromised with the first one. What's the point?
Vodafone: it's a way of better protecting yourself.
Intel: remote SIM provisioning would be a solution for this?
Vodafone: remote SIM provision is heavy and costly. It is not the only solution.
Telia Sonera: it seems that you are ignoring the GSMA work.
Vodafone: GSMA work may find different solutions that fit different use cases from us.
Deutsche Telekom supported this SID.
Vodafone commented that they have some potential solutions in mind and some examples can be found in TR 33.899.
KPN supported this SID.
Ericsson: is this related to 5G?
Vodafone: it's applicable to 5G, but potentially to LTE, UMTS and so on.
ORANGE: remove everything solution specific from the justification. We don’t need to say that we need something between the UE and the HSS, or that we will have a potential standard for that. This is coming from a solution in the TR 33.899 from 5G.
China Mobile supported this SID.
Gemalto: impacts of the algorithms.BT supported this.
ORANGE: out of scope of 3GPP, it doesn't have to be part of the objectives.
G&D: support of no algorithms in here.
Other supporters were added (e.g. 360.)
ORANGE: why changing the identifiers? We need a justification for this.
Vodafone: it's part of the study.It's not a study about changing profiles between operators.ORANGE commented that they wanted this into the justification.
G&D: identifiers can still be an output of the study, we can remove this statement to avoid confusion.

YesThe Chair commented that SA3 should do their own SID document and not integrate it wit the SA2 WID.
BT commented that the low latency issue hasn't been dealt with and it is not included in the objectives.
Huawei: this is way too early for us. I don’t believe that there is anything to look for us at this early stage.
Qualcomm supported but better to wait for a couple of meetings until SA3 gets more material from SA2. ORANGE agreed.
The number of companies agreeing to delaying were the same as the number of companies who wanted to start. The Chair commented that LG could bring the SID with contributions to have the work started if the progress in SA2 allowed to do that.
The SID was noted.

China Mobile confirmed that they have seen this happening. They don’t propose any solutions but they would like to address this.
ORANGE: are you proposing a DoS from the user to the network?
China Mobile: the attack comes from software, not the UE.
ORANGE: do you foresee something that needs to be done in 3GPP? Does GSMA know this problem?It's more appropiate to raise this issue in there.
