Vernam Cipher

  • Reference work entry
Encyclopedia of Cryptography and Security

This is an encryption operating on groups of 5-bit words, by means of coordinate-wise addition modulo 2 (see modular arithmetic). Normally, the CCIT2-code is used. The key should be a completely random, one-time key (see key).

The Vernam table for Z32 = Z2 5 (Gilbert S. Vernam, 1917) looks like:
