....bad idea for obvious reasons. 2.8 Problem 8 choice of encryption algorithm GCHQ wants people to use an unpublished block cipher with 64 bit block and key size called Red Pike. According to a report on the algorithm prepared in an attenpt to sell it to the Health Service, it is sinfilar to RC5 [22] but with a different key schedule. It will apparently be the standard for government traffic marked up to Restricted , and it is claimed that systems containing it may be less subject to export controls: health service officials have claimed that US companies operating in the UK may be allowed ....

.... Data dependent rotations were first used for encryption in a cipher developed by Becker in IBM in the late 1970 s [2] and later were used by Madryiga [8] in his cipher) This operation gained recognition in recent years after it was used by Rivest as the main building block for the RC5 cipher [12]. Data dependent rotations can be performed quickly in software and hardware. Combined with arithmetic operations (such as addition) this operation is very effective against linear cryptanalysis. Also, when carefully used in a cipher it can be made effective against differential cryptanalysis. ....

....there are 2 keys for which the cipher is theoretically breakable requiring about 2 known plaintexts. The analysis highlights the sensitivity of RC5 security to its key scheduling algorithm. Key Words: cryptography, private key ciphers, RC5, linear cryptanalysis, weak keys Introduction: RC5 [1] is a class of private key block ciphers designed to be efficiently implemented in software by utilizing three basic operations: exclusive OR, addition, and data dependent rotations. An RC5 cipher is designated as RC5 w=r=b where w represents the word size of the target processor in bits, r is the ....
....We use the notation L k and R k to represent the left and right half, respectively, of the cipher data after the (k Gamma 1) th half round. Also S k represents the k th subkey consisting of w bits associated with the (k Gamma 1) th half round and generated by the key scheduling algorithm of [1]. Letting L 2r 1 and R 2r 1 represent the left and right half of the ciphertext, respectively, the RC5 encryption algorithm is given by: L 1 = L 0 S 0 R 1 = R 0 S 1 for k = 2 to 2r 1 do L k = R k Gamma1 R k = L k Gamma1 Phi R k Gamma1 ) R k Gamma1 ) S k (1) where represents ....

....significantly di#erent performance characteristics. CAST is a program based on the CAST 128 block cipher algorithm that uses a 128 bit key to encrypt data for secure transmission [1] CAST 128 operates similar to other block cipher algorithms used in current networks, such as IDEA [13] and RC5 [19], however, CAST is in the public domain. Kernel : encryption arithmetic. ZIP is a data compression program based on the commonly used Lempel Ziv (LZ77) algorithm [33] The implementation can achieve di#erent levels of data compression by varying the algorithm s computational complexity and ....
