eXtended Tiny Encryption Algorithm (XTEA) – PART II

In this article, we will demonstrate eXtended Tiny Encryption Algorithm (XTEA). Don’t forget to read the Part I of TEA. XTEA (eXtended TEA) is a block cipher designed to fix weaknesses in TEA. Like TEA, XTEA is a 64-bit block Feistel cipher with a 128-bit key and a suggested 64 rounds. As per book “Information Security and Cryptology – ICISC 2003“ TEA is a 64-round … Continue reading eXtended Tiny Encryption Algorithm (XTEA) – PART II

Tiny Encryption Algorithm (TEA)- Part I

 Tiny Encryption Algorithm is a simple, powerful & notably fast encryption algorithm. Although TEA algorithm has a few weaknesses as it suffers from equivalent keys (Which left the room for related-key attacks) – each key is equivalent to three others, which means that the effective key size is only 126. It is Feistel type cipher, the algorithm relies on the alternate use of XOR and ADD … Continue reading Tiny Encryption Algorithm (TEA)- Part I
