one-way and trapdoor one-way functions, cryptanalysis, attack models, classical

cryptography. Block ciphers: Modes of operation, DES and its variants, RCS, IDEA,

SAFER, FEAL, BlowFish, AES, linear and differential cryptanalysis. Stream ciphers:

Stream ciphers based on linear feedback shift registers, SEAL, unconditional security.

Unit 2

functions, attacks on hash functions. Public-key parameters: Modular arithmetic, gcd,

primality testing, Chinese remainder theorem, modular square roots, finite fields.

Unit 3

Intractable problems: Integer factorization problem, RSA problem, modular square root

problem, discrete logarithm problem, Diffie-Hellman problem, known algorithms for

solving the intractable problems.

Unit 4

exchange: Diffie-Hellman and MQV algorithms. Digital signatures: RSA, DAS and NR

signature schemes, blind and undeniable signatures. Entity authentication: Passwords,

challenge-response algorithms, zero-knowledge protocols. Standards: IEEE, RSA and

ISO standards

Unit 5
