- n. The act or process of enciphering; encryption
Sorry, no etymologies found.
The encipherment table or “key register” was subsequently changed, though American code breakers gradually cracked it again.
To be on the safe side, the messages were super-encrypted with a 256-bit system specially made at the National Security Agency, and the double-encipherment was so complex that even NSA's own bank of supercomputers could only crack it with difficulty and after a lot of expensive time.
The duplication of channels, their known function, the brevity of the message, and the identical encipherment pattern told the Soviets much, even before the receipted signal was input into their computers.
"We're not sure, but probably an encipherment algorithm."
A pad was unmistakably for the purpose of encipherment, but a book looked quite innocent.
What's really clever is that the system is based on an independent input signal that's unique to the individual transmission-over and above the encipherment algorithm that's already built into the system. "
