Authentication method and system encrypting a ticket with an symmetric key, said symmetric key being encrypted with an asymmetric key

摘要

A security authentication method and system. After authenticating a user, an authentication server generates a ticket including information associated to the user. The authentication server encrypts the ticket using a symmetric key shared with an affiliated server. The affiliate server has a private key associated with the public key that the authentication server uses to encrypt the symmetric key. The authentication server uses the private key for creating a signature of the ticket. The affiliate server decrypts the symmetric key with its private key and then decrypts the ticket using the decrypted symmetric key. The affiliate server validates the signature by using the authentication server's public key.
