Process that validates the identity of the device and ensures that the entity is what it claims to be before a connectionĪ form of device authentication where an MD5 hash of a shared password (among other things) gets used to establish the identity The CLI command set utils ctl does not require hardware security tokens. Hardware security tokens are required for only the CTL Client. Signs used for file authentication, it may be used to sign the CTL file. In digest authentication, a request to a SIP user agent to authenticate its identity.Ĭisco Site Administrator Security Token (security token etoken)Ī portable hardware security module that contains a private key and an X.509v3 certificate that the Cisco Certificate Authority Process by which supported devices can request locally significant certificates by using Unified Communications Manager Administration.Ī file, which is created either with the CLI command set utils cli or with the CTL Client and signed by the Cisco Site Administrator Security Token (security token), that contains a list ofĬertificates for servers that the phone is to trust.
