¿µ¹®³»¿ë¿ä¾à The standard describes how ARIA can be used to provide confidentiality and/or integrity to RTP/RTCP packets, and to provide session keys for the respective security primitives. Specifically, detailed descriptions of the use of ARIA for the encryption transform and the key derivation function are defined as the same with the cases of AES. Furthermore, it defines new SRTP crypto suites of ARIA to be used to signal and negotiate them via SDES(Session Description Protocol Security Descriptions).
