What is "encipher"

Usage examples of "encipher".

This constitutes an excellent form of enciphered code, and just how precocious Alberti was may be seen by the fact that the major powers of the earth did not begin to encipher their code messages until 400 years later, near the end of the 19th century, and even then their systems were much simpler than this.

The system permits great flexibility: no longer did all messages have to be enciphered with one of a relatively few standard sequences of alphabets, but different ambassadors could be given individual keys, and, if it were feared that a key had been stolen or solved, a new one could be substituted with the greatest of ease.

Its author had the instinct for the cryptographic jugular, and he compressed into 64 pages virtually the entire known field of cryptology, including polyalphabetics with mixed alphabets, enciphered code, and cipher devices.

This information permits the cryptanalyst to sort the letters of the cryptogram so that all those enciphered with the first keyletter are brought together in one group, all those enciphered with the second keyletter in another group and so forth.

The cryptanalyst must align these one above the other so that letters enciphered with the same keyletter will fall into a single column.

But the digits resulting from an encoding were then enciphered with the disk just as if they were plaintext letters.

Electric impulses raced through the maze of wires, reversing the intricate enciphering process.

So Marshall shunned the scrambler telephone and relied on the slightly slower but much more secure method of enciphering a written message.

But even if the entire document had been delivered on time, the 25 minutes that remained until the attack would not have been sufficient time for all the steps needed to prevent surprise: reading the document, guessing that a military attack was intended, notifying the War and Navy departments, composing, enciphering, transmitting, and deciphering an appropriate warning, and alerting the outpost forces.

By the end of the century, cryptology had become important enough for most states to keep full-time cipher secretaries occupied in making up new keys, enciphering and deciphering messages, and solving intercepted dispatches.

So the German Foreign Office disguised the codegroups by enciphering them.

This would have the effect of enciphering one letter into another in a monoalphabetic substitution.

The advantage was not the mechanical enciphering and printing of the message.

A Dutch engineer, Hugo Alexander Koch, 49, viewed the system most comprehensively, pointing out in his patent that steel wires on pulleys, levers, rays of light, or air, water, or oil flowing through tubes could transmit the enciphering impulse as well as electricity.

He was halfway through enciphering it when there was a commotion in the yard outside as a fine coach rolled in.
