Cryptography deals with algorithms for encryption and decryption. For example encrypting a message with some key produces a new message from which the original message can be recovered only by someone who knows the inverse key. Cryptographic protocols are rules for exchanging messages using these cryptographic primitives.
Even if the cryptographic primitives are assumed to be secure, most
cryptographic protocols turn out to have errors which escape the attention
of their designers. For this reason formal verification of cryptographic
protocols is necessary to ensure their security properties. In this course
we will look at some cryptographic protocols, and methods for modeling and
verifying them.
