Description: This article deals with the questions of improving the cryptostrength of the algorithm of electronic digital signature (EDS) ElGamal with a composite module, based on the complexity of solving the factorization problem. To improve the reliability of electronic digital signature schemes with a composite module authors suggest using an additional parameter 'H, which is the hash value of the shared key users K, formed on the Diffie-Hellman parameters and signature r and S.
