Support for Secure Digest Algorithms for SIP Authentication
Avaya SBC supports the following secure digest algorithms for authentication challenge responses:
-
MD5 (Message Digest)
-
SHA-256 (Secure Hash)
-
SHA-512 (Secure Hash)
Secure digest algorithm is a simple challenge-response mechanism that allows a server (service provider) to challenge a client (Avaya SBC) request and allows a client (Avaya SBC) to provide authentication information in response to that challenge.
SHA-256 and SHA-512 are more secure and strong algorithms than the default algorithm, MD5.
For JITC deployments, Avaya SBC uses the algorithms in the following priority order (high to low):
For Non-JITC deployments, Avaya SBC uses the algorithms in the following priority order (high to low):
