Abstract. Helix is a high-speed stream cipher with a built-in MAC functionality. On a Pentium II CPU it is about twice as fast as Rijndael or Twofish, and comparable in speed to R...

In this paper we give a specification of a new block cipher that can be called the Courtois Toy Cipher (CTC). It is quite simple, and yet very much like any other known block ciph...
The block cipher RC2 was designed in 1989 by Ron Rivest for RSA Data Security Inc. In this paper we describe both the cipher and preliminary attempts to use both differential and l...

This document describes the RC5 encryption algorithm, a fast symmetric block cipher suitable for hardware or software implementations. A novel feature of RC5 is the heavy use of da...
— Software protection is increasingly necessary for uses in commercial systems, digital content distributors, and military systems. The Secure Software (SecSoft) architecture is ...
