WebFeb 29, 2024 · Then, choose an integer g, such that 1 < g < p, g**q mod p = 1 and g = h** ( (p–1)/q) mod p. q is also called g's multiplicative order modulo p in this algorithm. Then, choose an integer, such that 0 < x < q for this. Now, compute y as g**x mod p. Thus, Package the public key as {p,q,g,y} is this. And, Package the private key as {p,q,g,x} is this. WebProve the multiplicativity of the discrete logarithm: log_g(xy) = log_g (x) + log_g (y) mod (p - 1) for all x, y belongsto (Z/pZ)^x. Using this conclude that log_g (x^n) = n log_g(x) mod (p - 1) for all n belongsto Z as well. (Change of base for discrete logs).

WebWith modular hashing, the hash function is simply h(k) = k mod m for some m (usually, the number of buckets). The value k is an integer hash code generated from the key. If m is a power of two (i.e., m=2 p), then h(k) is just the p lowest-order bits of k. The SML/NJ implementation of hash tables does modular hashing with m equal to a power of ... http://www-math.mit.edu/~desole/781/hw6.pdf WebIn modular arithmetic, a number g is a primitive root modulo n if every number a coprime to n is congruent to a power of g modulo n.That is, g is a primitive root modulo n if for every integer a coprime to n, there is some integer k for which g k ≡ a (mod n).Such a value k is called the index or discrete logarithm of a to the base g modulo n.So g is a primitive root … eggs with heavy cream
