7.3Security aspects of 5G System - Phase 1 (5GS_Ph1-SEC) (Rel-15)
| Yes |
YesORANGE saw several problems with the definitions given in the CR for the SA1 TS. Besides, the requirement for 3GPP subscription credential is much wider in SA3. SA3 should send a LS to SA1 pointing out this.
Vodafone commented that they had offered this CR, but personally, Tim commented that giving security terms and solutions in a SA1 specification seems to be very strange.Tim preferred that SA1 referred to a SA3 specification or to 21.905.
Ericsson: the SA1 TS doesn’t belong to any phase. It's ok to specify these terms, we are going towards that direction anyway.
Oberthur: SA1 decided already not to refer to SA3 specs in this case.
Vodafone: SA plenary didn’t agree with SA1 and that was the reason why the CR was not accepted.
Oberthur: if we do nothing, this will be a maintained working assumption. The plenary asked to finalise the work, so the requirement cannot be removed. If it is removed, the work won’t be complete. ORANGE commented that SA1 and SA3 should coordinate, so the result is to remove this requirement.

YesORANGE asked to postpone the LS until an answer is reveiced from CT1.
Vodafone: this exists already. SA1 will challenge it.
BT: the big issue is how to identify securely identify the beacon that tells us in which network we are in. Vodafone: this is about the network being able to move their subscribers for commercial reasons.
Ericsson preferred to wait for the SA2 procedure before making a decision.

YesBT commented that the concept of slice is not fully understood in SA3, so this should go for phase 2. ORANGE suppported this. Ericsson, Nokia, Oberthur, Intel,KPN, China Mobile, LG,NEC wanted this for phase 2 as well.
Interigital, Qualcomm,CATT, Gemalto and AT&T preferred to treat this in phase one.
NTT-Docomo: if we don’t do protection in phase one, can we do it in phase two? ORANGE commented that we needed to know what was being protected, and SA3 didn’t have information about that.
Nokia: they are still discussing the business models in SA1.
Qualcomm: why are SA1 and SA2 including the NSSAI parameter in phase one then?this is puzzling.
AT&T: we are defining the 5G core in phase one. This would mean that we would be having slices without security, and this is not acceptable.
Nokia: the registration procedure in slicing becomes a very complicated procedure, this is currently being discussed in SA2.

Vodafone: ability to select RANs is in a SA1 spec. It is right to make statements so other groups can take action. Current phones cannot restrict access to 2G/3G.
BT agreed with this. The user should be aware about this. Emergency calls that can be made only in 2G, what happens?

YesCommented in 2072.
BT: this can also apply to 4G.
Huawei: The UE not present attack exists in 3G and 4G networks so we should retro fit it to them.
Nokia: it doesn’t work given the assumption from the last meeting.
KPN: it's only about authentication. The operator drops you to 4G/3G. The attack still happens. It might not be needed.
Interdigital: how's the complexity increased?
Huawei: compared to EAPS-AKA, the interface between the UE and ASF doesn't change.Compared to EAPS-AKA*, no hashes in option 1. Option 2 is comparable, roughly the same as EAPS-AKA*.
Nokia asked whether some other company felt the need to change the current solution in the TS. Either way seemed to be fine for the rest.
Huawei commented that the purpose was to have a working agreement and bring a pCR for the next meeting.
The documents were noted; the Chair welcomed more input for the next meetings to continue the discussions.

8.3.8Network slicing security
| Yes |
YesORANGE: no phases in SA1, so slice authentication doesn’t fit right now in phase one of the SA3 work.
Huawei: secondary authentication is mandatory.
ORANGE: this is specific to some use cases.
Huawei: we haven't agreed on anything about this topic yet. We need authentication after primary authentication.
ORANGE: this is not needed and it has been discussed several times.
Gemalto: other groups are working in slicing, we cannot skip them.
ORANGE: slice specific authentication is not being considered in the other groups.
Gemalto and China Mobile supported the proposal of having the slice authentication.
Ericsson didn’t see that this fit anywhere. Who will be doing this authentication on behalf of the operator? The operator itself to access their own slices after the primary authentication?
ORANGE: there is no assumption in SA2 for phase one in the slice authentication topic.
The Chair commented that he wasn't sure about having slice authentication for SA3's phase one.

ORANGE: exposure to third parties is not clear. Huawei agreed to refine this.
ORANGE added that external work can be added in the objectives without mentioning the other 3GPP groups.
The Chair commented that December 2017 was too ambitious given the current workload. Besides, ORANGE mentioned that there was no meeting before September 2017 so presenting this for information was impossible.
ORANGE: we are bound to other work items, we may have to wait for their results and delay the work.

| Yes |
YesORANGE: who's the user? How does it impact the core network? I don’t agree with the biometric authentication.
Alibaba: the original conclusion was TBD.
Vodafone: we already have authentication of the user. The question should have been about additional authentication mechanisms in phase one. The asnwer was TBD. The origiinal question is wrong, misleading. Vodafone didn't agree with the document and admitted that the original agreed question was poor.
BT: this implies creating a database for biometric data and it implies a higher seccurity risk. Locally is fine, but trying to centralise it would be risky.
Alibaba: there are solutions available to solve the high security risk of having a centralised database.
Vodafone: we might consider it for phase two, but we don’t have a SID for phase two yet.

YesEricsson pointed out that the discussion proposes a study but this is a work item proposal.
Huawei commented that this is a short WID and that’s the intention. Ericsson supported this.
BT commented that the scope misses security functions that pass on the interface. Not clear whether this is for Rel-15/ 5G. Status of the underliying 3GPP access network to be inclluded in the scope in order to support this WID.
Nokia commented that the dates proposed were wrong (they don’t show SA dates and what it shows in SA3 dates is very unrealistic).
Vodafone commented that the entities to be secured need to be identified: what do they mean with "users" here? The scope needs to be more specific.
MCC commented that the output should be CRs impacting TS 33.187. The wrong table was filled up.
MCC commented that in section 8 no 3GPP working groups should be added since the will not be involved in the SA3 WID work.

It was confirmed that SGP.22 was a GSMA public document so it was correct to reference to it.
MCC commented that the paragraph "In the latest version of SGP.22 when drafting this TR,.." should be removed as no mentioning of the time when the spec was drafted should be put into a specification. Vodafone agreed to replace it with a reference to SGP.22 as Rapporteur's work.

KPN agreed with Vodafone.
MCC commented that they felt uncomfortable with taking a solution from GSMA and modifying it.Mirko would check this internally.

| Yes |
YesBT: End-to-end media IMS could apply here.
Verizon: just have integrity protection in this situation.
KPN: we would be happy to transport data for Vodafone. No need to change the service. The regulation in Netherlands is going towards device manipulation. If the UE is moving towards end-to-end encryption we don’t need to act further. Everything can be solved in the roaming agreement.
Vodafone: Location of the customer is ON. No impact in LI if running only integrity protection.
ORANGE: the LI requirement in the VPLMN needs to be fulfilled without the help of the HPLMN.
Vodafone: the VPLMN needs to ask HPLMN not to allow cyphering. We tell the customer that the traffic will not be encrypted in certain countries. We have the tools to know where the customer is and act on it. This is all covered in the TR.
ORANGE: TC LI and SA3-LI are not proposing what needs to be done. SA3 doesn’t have the right skills to understand the LI requirements.
BT: SA3-LI should not act on the service architecture either. SA3 should give feedback on the way the think it should be done with the minimum impact. Confidentiality is fine enough.
Vodafone proposed to have conference calls to discuss the response LS.
ORANGE: SA3-LI is meeting before Reno, we need to respond before.

Nokia: fresh start is too cumbersome and there is not time, let's bring the 401 approach. NEC supported it.
NTT-Docomo pointed out to fix the normative language mistakes that are coming from 401 so as not to make the same errors. The proposal would be to bring things from 33.401, but instead of copying directly into the TS have a running pCR to be able to adjust the language firstly.

YesQualcomm questioned combining LTE/NR in the same signalling as Ericsson proposed. They would support a negotiation where it is indicated the algorithms supported for LTE and for NR.
Nokia: maybe we are creating a problem by defining two sets.
The Chair clarified that cryptographic algortihms are the same in NR.
Qualcomm: inputs to NR are not the same as in LTE since the bearer IDs are different. We should have separate bits to say these algos support LTE and these support NR.
Qualcomm: Happy to do the /NAS based solution as long as we have separate bits for the NR capability and for the LTE capability.
Ericsson: in the case the issue is that the legacy eNodeB doesn’t understand the new capabilities.All eNodeBs would need to be upgraded.
Huawei: the NAS solution is the way to go.
How do you transfer the capabilities to the MeNodeB? If you come to the Ericsson: MeNodeB from a legacy eNodeB handover (x2 interface) you will not get this information.
Huawei: the legacy issue is not a priority now.

The sentence will be reworded to transfer the message to SAGE in any case.

Motorola commented that they were not involved personally in the discussion and that they would have to check with their colleagues.
Qualcomm pointed out that SA2 is waiting for SA3's response, the solution is not rejected.
Verizon: Let's send SA2 our security concerns for SA2 solutions and comment what SA2 should do.
Nokia: SA2 cannot address the detailed security concerns.
Intel commented that SA3 should understand why the Qualcomm solution doesn't work given that it is in our TR.
Ericsson: SA2 is asking to assess the security solutions they propose and SA3 should reply to that. Afterwards we can decide whether the existing solution is better.

| Yes |
YesEricsson: the procedure doesn't have security concerns. Let SA2 deal with this.
Verizon: there are security concerns when sending the SUPI.
Nokia: SA2 has defined the registration procedure with the SUPI. They have to adapt their procedure accordingly to what SA3 proposes. We don’t need an extra message as Ericsson proposes since it's already there.
Huawei: if the AMF doesn’t need the message with the temporary ID it has to request the identity of the user. Something needs to be done.
Qualcomm: in that scenario in 4G it's a reject from the MME. So a new attach is performed. That's what the AMF will do, reject so the process restarts.
Nokia: SA2 can use the identity request procedure as well, but they may not want it for non-3GPP networks.

7.2EPC enhancements to support 5G New Radio via Dual Connectivity (EDCE5) (Rel-15)
| Yes |
YesNokia: option one is pure Rel-13 dual connectivity.
Ericsson: it's ok to use the same key as long as you don’t change the termination point; this was agreed in SA3 and in you are contradicting this decision here.
Nokia: UE performance is affected when rekeying. Ericsson didn’t understand this issue: There weren't performance issues in the dual connectivity. There is no disruption of the service.
Verizon: performance impact is not to be decided in SA3. RAN2 wants a good security solution.We should go for option 3.
Qualcomm: option 3 has more complexity from the security perspective.
Nokia: the number of keys exchanged is reduced and the performance is improved.
Huawei pointed out that RAN2 would like a transparent process.
Qualcomm: the transparent exchange cannot be achieved in terms of option 2 and option 3.
Ericsson: transparency means that the network indicates the UE when to change the key. We have a different understanding of option one despite that most companies seem to go for this option.
China Mobile: different keys for LTE PDCP and NR PDCP?
Qualcomm: the algorithm is the same in both LTE and PDCP, it's only the message that changes.
Ericsson: all three options are possible, but the principle in option one is the most important from the security point of view. Nokia agreed but leaving the door open for using the other two options in a specific circumstance. Qualcomm didn’t see the security gain for having the possibility of using the other two options.
Nokia: we agreed and implemented option 1 in Rel-12. We should also agree at least on option 2. Huawei agreed.

YesNTT-Docomo wasn't sure whether this worked for the already proposed schemes. An editor's note was proposed to warn about this.
Ericsson: it's simpler is to send the SUPI when the NAS security is turned ON. Huawei supported this.
Ericsson: Let's not make a decision in this meeting and analyze how to fulfil the LI requirement for the next meeting.
NTT-Docomo: keep the headline to have a placeholder. Arguments for a solution should be brought for the next meeting.
Nokia: keep the assumption. Some companies disagreed with this.

YesEricsson was concerned that this would re-open long discussions in SA1. The SA1 TS is not phase specific.They have agreed on this topic and they were worried that SA3 would be bringing this phase approach to SA1.
Ericsson asked to have minuted that they disagreed with the removal of the definition of subscription credential from the SA1 TS as this LS proposes. Sony had the same objection.

YesBT: if the operator is the only one allowed to provide the handsets this works, but when they are out of their of their control we agree with Vodafone.
Qualcomm: there will be operators who will choose to store in the UICC, and there will be operators who will have control over the handset distribution model and they can choose to store in the ME. Why do we standardise to avoid operators having this option?
Vodafone: the disagreement on the ME part relies on the provisioning, not the security. Let's add an editor's note on this.
