METHOD FOR CONFIRMING AUTHENTICITY OF DISCONTINUOUS MESSAGE Russian patent published in 2007 - IPC H04L9/00 H04L9/08 

FIELD: electric communications and computer engineering, in particular, methods and devices for cryptographic transformation of data.

SUBSTANCE: the essence of method is in generation of binary vector, appropriate for date and time of discontinuous message transfer, generation of binary vector of secret parameter, generator of binary identification vector and addition thereof to discontinuous message. Message is different from known methods because it includes additionally forming a random binary vector and binary vector of protection key, while binary vector of secret parameter is formed by double compressing of random binary vector, while binary identification vector is formed by transformation in circle of residue class by module p of binary vector, appropriate for data and time of transfer of discontinuous message and binary vector of secret parameter.

EFFECT: rejection of false messages, increased speed of process of confirming authenticity of discontinuous message.
