The paper considers error probability in every of four message block integrity checking methods: digital signature, cyclical redundant code, control sums in vector space over a field of two elements and control sums in a ring of integers. Comparison of asymptotic representations of transmitted binary signal and for large transmitted block’s volume is presented in the paper.
Values of main members for asymptotic decomposition are obtained for the integrity checking methods noted. These values are calculated as an example for parameters of TCP protocol segments.
