Abstract
A system for preventing hijacking of communication of a first device with a second device upon replacement of the second device with a logical replica, comprising: a first device, comprising: a time-restricted accessible memory, wherein data on the memory written at a time cannot be overwritten with data from a future timestamp; a second device, comprising: a time-restricted accessible memory, wherein data on the memory written at a time cannot be overwritten with data from a future timestamp; a processor configured to execute instructions causing the processor to effectuate operations, comprising: establishing and maintaining a temporal consonance between the first and second devices by logging an identity of each other at each interval of message exchange in the memory of the first and second devices; wherein message exchange is restricted based on a trust level between devices, wherein the trust level is based on a certain history threshold of communication.
