First, here is a definition of the exchanges between two actors (say, Alice and Bob) to start a secure session: Alice sends a 16-byte random number to a1 … a16 to Bob. Bob replies with […]

In the few coming posts, we will define a secure channel protocol from scratch as an example, and provide an implementation for it. This example will also be used as a way to introduce the cryptographic mechanisms that exist in Java Card. Be careful, this is not a tutorial on cryptography. I am not a […]
