Abstract:
1. A method of sharing a self synchronizing cryptographic device among a plurality of communications links, the method comprising: buffering in a memory at least a first set of data received from a first communications link, a third set of data received from a second communications link, and a second set of data received from the first communications link, wherein the first communications link is different than the second communications link; transferring the entire first set of data, including a tail section of the first set of data, from the memory to the cryptographic device; keeping a copy of the tail portion of the first set of data in the memory, wherein the tail portion of the first set of data is both transferred to the cryptographic device with the entire first set of data and kept in the memory; thereafter transferring at least part of the third set of data from the memory to the cryptographic device; and thereafter transferring the tail portion of the first set of data kept in the memory followed by the second set of data from the memory to the cryptographic device, wherein a data quantity of the tail portion of the first set of data is sufficient to reestablish automatically cryptographic synchronization of the cryptographic device.
