In ElGamal system, each user has a private key x. and has three components of public key − prime modulus p, generator g, and public Y = g x mod p. The strength of the ElGamal is based on the difficulty of discrete logarithm problem. The secure key size is generally > 1024 bits. Today even 2048 bits long key are used. In cryptography, the ElGamal encryption system is an asymmetric key encryption algorithm for public-key cryptography which is based on the Diffie–Hellman key exchange. It was described by Taher Elgamal in 1985. ElGamal encryption is used in the free GNU Privacy Guard software, recent versions of PGP, and other cryptosystems. The Digital Signature Algorithm (DSA) is a variant of the ElGamal signature scheme, which should not be confused with ElGamal encryption. ezgo golf cart seat skins

Web1 Answer. Your answer is in the paper Elliptic curve cryptosystems from Neal Koblitz: Set up an elliptic curve E over a field F q and a point P of order N just the same as for EC-DDH as system parameters. You need a public known function f: m ↦ P m, which maps messages m to points P m on E. WebOur WRSS scheme builds upon the CRT-based secret sharing scheme previously studied by [26,4,21].
