RC algorithms

(Ron's Code or Rivest's Cipher algorithms) A family of secret key cryptographic algorithms from RSA Security, Inc., Bedford, MA (www.rsa.com). Although RSA (formerly RSA Data Security and acquired by EMC in 2006) is widely known for its public key methods, its secret key algorithms are also widely used. Ronald Rivest is the "R" in RSA.

Designed as a replacement for DES, RC2 uses a variable key and the block cipher method. RC4 uses a variable key and stream cipher method. Both RC5 and RC6 are block ciphers with variable keys up to 2,040 bits. RC6, designed by Rivest and others, uses integer multiplication for improved performance. RC6 was created to conform to the AES standard and was a finalist in the competition for the AES algorithm. See RSA, EMC, AES and DES.

NIST noted that the submitters of the two algorithms that received the most comments regarding an increase in rounds, RC6 and Rijndael, did not choose to increase the number of rounds at the end of Round 1 (when "tweak" proposals were being considered).
The two papers presenting attacks on variants of RC6 both present a small, but iterative, statistical bias in the round function.
For example, should the whitening in MARS, Twofish, RC6, and Rijndael count as rounds or partial rounds?
RICAVISION's product line currently consists of two (2) groups: Microsoft Vista SideShow products and Microsoft certified Windows Vista Remote Control RC6 receivers.
The RC6 continues the Boart Longyear safety initiative and offers several key safety features including intuitive control panels, low noise operation, a safety cage and emergency trip wires.
Safety has always been a top priority for Boart Longyear, and the RC6 is no exception with it's state-of-the-art safety features," said Justin Warren, Boart Longyear global product manager for capital equipment.
With robust steel crawlers and an optional radio remote control for driving, the RC6 can be driven on slopes up to 30 degrees while the operator maintains a safe distance from the rig when unloading or driving on uneven terrain.
The RC6 algorithm is currently a National Institute of Standards and Technology (NIST) finalist to become the Advanced Encryption Standard (AES) that will replace DES as the most widely used symmetric algorithm.
