Discrete algorithm

Discrete logarithm problem in elliptic curve cryptography

For example, in the group of the integers modulo p under addition, the power bk becomes a product bk, and equality means congruence modulo p in the integers. At the same time, the inverse problem of discrete exponentiation is not difficult it can be computed efficiently using exponentiation by squaring , for example.
