This feature provides support for the ARIA algorithm cipher encryption for SRTP. This
is an alternative option to the existing support for the AES algorithm. ARIA is a
symmetric key block cipher algorithm standard developed by the Korean National
Security Research Institute. The ARIA offered suite supports 128-bit and 192-bit key
encryption sizes with HMAC SHA-1 cryptographic hash function.
ARIA encryption is enabled by the new parameter, AriaProtocolSupport. The required
ARIA crypto suite for SRTP is according to the existing parameter, SRTPofferedSuites.
For ARIA encryption of SRTP, the device must be installed with the relevant Software
Upgrade Feature Key.
