Cryptography

Symmetric Ciphers

• Kasiski examination: hacking Vigenere cipher
• des cipher (Data Encryption Standard)
• serpent cipher: Advanced Encryption Standard contest second place

Stream Ciphers

• rc4: simpliest stream cipher

• a5 and comp128: implementation of the A3, A5 and A8 functions defined in the GSM standard

A3 is used to authenticate the mobile station to the network. A8 is used to generate the session key used by A5 to encrypt the data transmitted between the mobile station and the BTS

Assymmetric Ciphers

• rsa: simpliest modulo operation based assymmetric cipher, one of the first public-key cryptosystems and is widely used for secure data transmission

Cryptographic Hash Functions

• CubeHash: a cryptographic hash function submitted to the NIST hash function competition, SHA-3 semi-finalist
