ElGamal algorithm not only used for data encryption can be used for digital signatures, their safety depends on the calculation of a finite field discrete logarithm this problem. Key to the method. First of all, choose a prime number p, the two random numbers, g and x, g, x <p, computing y = g ^ x (mod p), for its public key y, g and p. Private key is x. g and p by a group of users to share. ElGamal for digital signatures. Information was signed M, first choose a
