WebDiscrete logarithms are fundamental to a number of public-key algorithms, including Diffie-Hellman key exchange and the digital signature algorithm (DSA). This section provides a … The discrete logarithm problem is considered to be computationally intractable. That is, no efficient classical algorithm is known for computing discrete logarithms in general. A general algorithm for computing logb a in finite groups G is to raise b to larger and larger powers k until the desired a is found. This … See more In mathematics, for given real numbers a and b, the logarithm logb a is a number x such that b = a. Analogously, in any group G, powers b can be defined for all integers k, and the discrete logarithm logb a is an integer k such that … See more Powers obey the usual algebraic identity b = b b . In other words, the function $${\displaystyle f\colon \mathbf {Z} \to G}$$ See more There exist groups for which computing discrete logarithms is apparently difficult.
