name: AS
full_form: Access Stratum
context: This clause provides the details for AS security algorithms negotiation and consideration during the UE initial AS security context establishment. Each gNB/ng-eNB shall be configured via network management with lists of algorithms which are allowed for usage. There shall be one list for integrity algorithms, and one for ciphering algorithms. These lists shall be ordered according to a priority decided by the operator. When AS security context is to be established in the gNB/ng-eNB, the AMF shall send the UE 5G security capabilities to the gNB/ng-eNB. The gNB/ng-eNB shall choose the ciphering algorithm which has the highest priority from its configured list and is also present in the UE 5G security capabilities. The gNB/ng-eNB shall choose the integrity algorithm which has the highest priority from its configured list and is also present in the UE 5G security capabilities. The chosen algorithms shall be indicated to the UE in the AS SMC. The chosen ciphering algorithm is used for ciphering (when activated) of the user plane and RRC traffic. The chosen integrity algorithm is used for integrity protection (when activated) of the user plane and RRC traffic. Activation of ciphering and integrity protection for the RRC traffic shall be done as defined by clause 6.7.4. Activation of ciphering and integrity protection for the user plane traffic shall be done based on the UP security policy received from the SMF as defined by clause 6.6.2.
description: The Access Stratum (AS) is a protocol layer in the 5G system architecture responsible for managing access-related security functions, including algorithm negotiation and selection for integrity protection and ciphering of user plane and RRC traffic. It plays a crucial role in ensuring secure communication between the User Equipment (UE) and the network.
explanation: AS is classified as a Protocol because it defines the rules and procedures for accessing and securing the network, specifically focusing on the negotiation and selection of security algorithms for protecting user data and signaling information.
