METHOD OF DEACTIVATION AND REPEATED ACTIVATION OF PROTECTIVE MODULES Russian patent published in 2008 - IPC G07F7/10 G06F12/14 

FIELD: information technology.

SUBSTANCE: protective module has a set of registers, containing certain values. At least one control message is transmitted, containing an executable code, for loading the protective module into the memory, which is then later executed. The value of the registers are combined and/or encoded, or converted to an unreadable form. The method provides for repeated activation of the protective modules, previously deactivated. In that case the method involves a stage of sending another message, containing an executable code for repeated activation of the modules. The executable code has an inverse function to the function of the executable code, used for deactivating the protective modules.

EFFECT: provision for deactivation of protective modules by deleting operators for providing protection from unauthorised access without transmitting the protective modules themselves to the operator from the source and provision for repeated activation.
