System and method for synchronizing one time pad encryption keys for secure communication and access control

摘要

A method for generating an identical electronic one-time pad at a first location and a second location, the method comprising the steps of: (a) providing a first electronic device at the first location and a second electronic device at the second location, each of the first and the second electronic devices having: (i) a non-volatile memory; (ii) a processor; (iii) at least one table of true random numbers being stored on the non-volatile memory, the table being identical for the first and the second electronic devices; and (iv) at least one software program for obtaining a true random number from the table, the software program being stored on the non-volatile memory and the at least one software program being operated by the processor; (b) providing a communication channel for communication between the first electronic device and the second electronic device; (c) selecting a selected true random number from the table at the first and the second electronic devices according to a selection procedure, the selection procedure being identical for the first and the second electronic devices, the selection procedure including exchanging at least a portion of a key between the first and the second electronic devices over the communication channel, such that the selected true random number is identical for the first and the second electronic devices; and (d) forming at least a portion of the identical electronic one-time pad at the first and the second locations with the selected true random number.
