Web1. Cryptography. In this lesson we will cover a few cryptographic concepts along with the related fields of digital forensics and steganography. Cryptography is the process of encoding or decoding messages and data. In this lesson we will learn about cryptography in three broad sections, ciphers, encryption, and hashing. WebThe security of the ElGamal algorithm is based on the difficulty of solving the discrete logarithm problem. It was proposed in 1984 and is also a double-key cryptosystem, which can be used for both encryption and digital signature. If we assume that p is a decimal prime of at least 160 bits, and p-1 has a large prime factor, and g is the ...

These parameters are used in many lattice-based (small roots) algorithms to tune the lattice size. Conceptually, m (sometimes called k) and t represent the number of "shifts" used in the lattice, which is roughly equal or proportional to the number of rows.
