Cryptography
Design of cryptographic mechanisms for ensuring the safety concepts for purposes of Privacy, And authenticity ofintegrity information, but also for other concepts such as anonymity.
Cross-certification

Asymmetric Cryptography
The algorithms are public, but each individual has a pair of keys: one secret allowing him to perform operations that he alone is supposed to be able to do (or signature decryption), While its public key broadcasts to enable its partners to implement the reciprocal transactions (or signature verification Encryption message). Both keys have a role " asymmetric , Hence the terminology.
A well known and widely used is theRSA.
