FIELD: technological processes. ^ SUBSTANCE: invention may be used both at software and hardware implementation levels in computing and information systems for cryptographic protection of information in digital form. As keys, sequence of prime numbers (PN) in a row are used, order numbers (indices) of which are vectors of users initialization. For identification individual number of users is used. User with one personal number may enter different systems, where there is a current PN value corresponding to them from prime numbers range, which is licensed for this system. Size of stated sequence forms circle, that is after the last PN goes the first PN. Change of keys is done by shifting the register by correct time signals. ^ EFFECT: improves reliability of information protection. ^ 2 cl, 1 dwg
