Abstract
SEPP 1 forms a first TLS protected N32-c connection between with SEPP 2 so that SEPP 1 and SEPP 2 are respectively a TLS client and server. A TLS protected second N32-c connection between with SEPP 2 so that SEPP 1 and SEPP 2 are respectively a TLS server and client. On forming the first and second TLS protected N32-c connections, respective first and second shared secrets are formed. First and second master keys are obtained from the first and second shared secrets, respectively. N32-f context IDs are created by each SEPP on setup of the first and second N32-c connections. Based on the first master key and the first N32-f context ID, a first session key is produced for encryption of a first N32-f request to the second security edge proxy and correspondingly a second session key is produced for decryption of a second N32-f request from SEPP 2.
