Anna University CS67 01 Cryptography and Network Security Syllabus Notes 2 marks with answer is provided below. RC5 algorithm. In cryptography, the Tiny Encryption Algorithm (TEA) is a block cipher notable for its simplicity of description and implementation, typically a few lines of code.It was designed by David Wheeler and Roger Needham of the Cambridge Computer Laboratory; it was first presented at the Fast Software Encryption workshop in Leuven in 1994, and first published in the proceedings of that workshop. L is pre initialized to 0 value before adding secret key K to it. Research Papers (See also [Book Contributions].)

Types Of Wholesaler, Depending on input plain text block size, number of rounds and key size, various instances of RC5 can be defined and each instance is denoted as RC5-w/r/b where w=word size in bits, r=number of rounds and b=key size in bytes. In: Lecture Notes in Computer Science. A particular (parameterized) RC5 encryption algorithm is designated as RC5-w/r/b, where w is the word size (one block is made of two words), r is the number of rounds (\(r = 2h\) A novel feature of RC5 is the heavy use of data-dependent rotations.RC5 has a variable word size, a variable number of rounds, and avariable-length secret key.
