Uses Trapdoor function to enable use for encryption and digital signatures. One-way trapdoor functions can be inverted with knowledge of trapdoor factorization information. ECC Leverages discrete logarithm characteristics El Gamal Used in recent versions of PGP DSA A Federal Information Processing Standard for digital signatures (FIPS 186) Hash Algos MD5 - SHA1 - SHA256 - FORK256 - RIPEMD160 - GOST - TIGER MD5 128 Bit Hash Value SHA1 160 Bit Hash Value SHA256 256 Bit Hash ValueFORK256 256 Bit Hash Value GOST 256 Bit Hash Value TIGER 192 Bit Hash Value Key Exchange Algos Diffie Hellman (DH) - Menezes-Qu-Vanstone (MQV) - Key Exchange Algorithm (KEA) - Elliptic Curve DH (ECDH) RSA Encryption Formula C = Me % n RSA Decryption Formula P = Cd % n EC Formula y2 = x3 + Ax + B Symmetric Decryption Formula P = D(k,c) Symmetric Encryption Formula C = E(k,p) Cipher disk invented by ___ in Year ____
