Abstract: A method and an apparatus for mutual authentication in a DCAS(Downloadable Conditional Access System) are provided to supply a mutual authentication protocol between an authentication server of a head-end and a security module of a DCAS in a cable network. A security module(121) generates first share session key from a session key generation information for the generation of a share session key received from an authentication institution(130). The security module generates a signature certification message for the generated share session. An authentication server(111) receives the signature certification message, and generates a second share session key from the signature certification message. The authentication server transmits the signature certification message for the second share session key to the security module.
