Abstract:
An encrypted link is established with multiple ciphers. During a handshake protocol when establishing a secure session, at least two sets of cipher suites are transmitted to a server by a client. A choice cipher suite for each set of the at least two sets of cipher suites are received by the client from the server. The client selects a first choice cipher suite from among the choice cipher suites received from the server. The client establishes a connection with the server using the first choice cipher suite to encrypt the connection.
