The RC5 encryption algorithm is a fast, symmetric block cipher suitable for hardware or software implementations. A novel feature of RC5 is the heavy use of data-dependent rotations. RC5 has a variable-length secret key, providing flexibility in its security level.

1998年12月1日 · RC5. SHARK. SQUARE. MISTY1 and MISTY2. 3-WAY. Brute Force Attacks Resistance against brute force attacks is determined by the general parameters of the cryptographic algorithm -- key length, output size, and size of the internal state. For encryption algorithms, the most important brute force attack is an exhaustive key search.

Excellence in Programming Awards. By Jonathan Erickson, May 01, 1997 Cryptographer Ron Rivest and PC pioneer Gary Kildall are this year's recipients of our annual award honoring achievement in the world of software development.

2002年4月1日 · We work in a mature field now." Yeah, right. Working software pros know better. Can you imagine concepts like mindshare and the "hype trajectory" transplanted to, say, aeronautics? Daring engineers design ... concrete aircraft! "They're maintenance-free! Built to last, with a mold-on upgrade path (MOUP)." Venture capitalists sign on. Catapulted prototypes …
