Why do we use groups, rings and fields in cryptography?

WebJul 11, 2003 · In many cases the security of a cryptographic scheme based on computational Diffie–Hellman does in fact rely on the hardness of the decision Diffie–Hellman problem. In this paper we construct concrete examples of groups where the stronger hypothesis, hardness of the decision Diffie–Hellman problem, no longer holds, … Webthe cryptographic group that is employed in protocols is a large prime-order subgroup of the group E(F p) of F p-rational points on E. The group of rational points consists of all solutions (x;y) 2F2 p to the curve equation together with a point at in nity, the neutral element. The number of F p-rational points is denoted by #E(F Group-based cryptography is a use of groups to construct cryptographic primitives. A group is a very general algebraic object and most cryptographic schemes use groups in some way. In particular Diffie–Hellman key exchange uses finite cyclic groups. So the term group-based cryptography refers mostly to cryptographic protocols that use infinite nonabelian groups such as a braid group. simplisafe app for fire tv

Many cryptographic protocols rely on the hardness of solving the Discrete Logarithm Problem (DLP) in special groups, one of which is the integers reduced modulo a large integer. To guarantee that the DLP is hard to solve, the modulus must be a large prime number. Increasing its size boosts on security, but also makes ... simplisafe app for iphone
