Abstract: A technique is provided for extending a handshake communication between a communication device and an application server. The application server receives at least two messages from the communication device, each message comprising a handshake index and triggering a handshake session so that the application server negotiates with the communication device a set of cryptographic parameters. For each received message, the application server stores a negotiated set of cryptographic parameters in correspondence with a connection state index depending on the handshake index. The application server activates one of the stored sets of cryptographic parameters to establish a secured connection with the communication device.
