FIELD: computer technology.
SUBSTANCE: invention relates to means for reaching an agreement on a secret value. The second device contains a receiver made with the possibility of receiving information indicating verification data h from the first device, a processor made with the possibility of calculating a common secret s based on an integer value b, an equation and system parameters. The processor is made with the possibility of calculating b based on a key exchange protocol. The first device has a number a, which is in approximate agreement with the number b. The first device contains a processor made with the possibility of determining the common secret s based on an integer value a, an equation and system parameters and determining verification data h. The first device additionally contains a transmitter made with the possibility of transmitting information indicating verification data h to the second device.
EFFECT: increase in the accuracy of the agreement on the secret value.
