STREAM CIPHER

E0 (cipher)         
E0 is a stream cipher used in the Bluetooth protocol. It generates a sequence of pseudorandom numbers and combines it with the data using the XOR operator.
XOR cipher         
ENCRYPTION BY SIMPLE EXCLUSIVE-OR LOGIC OPERATIONS
Simple XOR Cipher; Simple XOR cipher; XOR encryption; Xor encryption; Xor cipher
In cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles:
Caesar cipher         
  • The Caesar cipher is named for [[Julius Caesar]], who used an alphabet where decrypting would shift three letters to the left.
  • A construction of two rotating disks with a Caesar cipher can be used to encrypt or decrypt the code.
  • The distribution of letters in a typical sample of English language text has a distinctive and predictable shape. A Caesar shift "rotates" this distribution, and it is possible to determine the shift by examining the resultant frequency graph.

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
