Abstract
A conference session key distribution method used in an ID-based cryptographic system includes selecting two different temporary secret keys, generating a message and generating session key generation variables using the temporary secret keys of a session initiating party. Only valid participating parties receive the session key generation variables. Each party determines the session shared key from the session key generation variables.
