ARIA Cipher Support
Previous and the current Oracle® Enterprise Session Border Controller releases have provided support for the Secure Real-Time Transport Protocol (SRTP), as defined in RFC 3711, to encrypt and authenticate Real-Time Transport Protocol (RTP) and Real-Time Transport Control Protocol (RTCP) media streams. Concurrent support for Session Description Protocol Security Descriptions (SDES) enabled the exchange of SRTP keying material. These releases have supported a single encryption algorithm, Advanced Encryption System (AES) counter mod with 128-bit keys
This release supports ARIA, a block cipher selected by the Korean Agency for Technology and Standards as a standard cryptographic Technique. The Oracle Oracle® Enterprise Session Border Controller now supports the ARIA cipher with a 192-bit key in counter mode for RTP and RTCP encryption; authentication is supported by HMAC_SHA1 with either 32-bit or 80-bit keys.
