For extending a handshake communication between a communication device (CD) and an application server (AS), the application server (AS):
receives at least two messages from the communication device (CD), each message comprising a handshake index and triggering a handshake session so that the application server (AS) negotiates with the communication device (CD) a set of cryptographic parameters,
for each received message, stores the negotiated set of cryptographic parameters in correspondence with a connection state index depending on the handshake index,
activates one of the stored sets of cryptographic parameters for establishing a secured connection with the communication device. |
