FIELD: information technology. ^ SUBSTANCE: method of generating and verifying an electronic digital signature includes the following sequence of operations: multi-bit binary number p is generated, a secret key in form of a multi-bit binary number x is generated, an open key is generated on the secret key in form of a multi-bit binary number y by raising the multi-bit binary number x to the power of a z-bit binary number k modulo p, where z>16, an electronic document, which is represented by a multi-bit binary number H, is received, depending on the value H and the value of the secret key, an electronic digital signature is created in form of a pair of multi-bit binary numbers (R,S), a first A and a second B authentication multi-bit binary number are formed and then compared, and authenticity of the electronic digital signature is indicated by coincidence of their parametres. ^ EFFECT: faster generation and authentication of an electronic digital signature. ^ 3 cl, 4 ex, 2 app |
