Using the Vigenère cipher with the key k, the message m was encrypted into the cryptogram c.

m = TRANSMITTINGELECTRONICDATA

k = BITLOCKER

In a symmetric algorithm a single key participates in both encryption and decryption.

Stream ciphers are often built using linear feedback shift registers (LFSRs) because they can be easily implemented in hardware.

Using the Homophonic cipher and the key, represented by the table below, the cryptogram C was obtained.

Substitution and permutation underlie both classical encryption algorithms and many modern ones.
