TD S2 160016 LS from SA WG3: Reply LS to RAN2 for clarification of security overhead for LTE V2X. (SA WG3) (Revision of TD S2 154130).
Abstract: SA WG3 thanks RAN WG2 for the LS regarding Clarification on security overhead for LTE V2X.SA WG3 would like to inform RAN WG2 that SA WG3 has agreed to undertake the study on the security aspect of LTE V2X Followings are the security related questions on the LS and SA WG3 would provide corresponding answers: Question 2: Is there a need to define any 3GPP specific security mechanisms in addition to existing security protocols? From SA WG3's point of view, whether there is any need to define any 3GPP specific security mechanisms in addition to existing security protocols and whether existing security protocols fulfils the LTE V2X security requirements captured in the SA WG1 study will be determined by SA WG3 based on the LTE V2X security study SA WG3 has agreed to undertake. Question 3: If the answer for Question 2 is affirmative, what is the corresponding size of any security overhead? This will be determined base on the outcome of the SA WG3 LTE V2X security study. Action: SA WG3 kindly asks RAN WG2, RAN WG1, SA WG1, and SA WG2 to take above into account in their following work.
