....is reluctant to use all of the processor registers, speed crypt on the VAX uses a SED (UNIX Stream EDitor) script that replaces certain memory references with register references in the assembly code. A. 3 Implementation Alternatives Fast crypt implementations by Baldwin[i] Bishop[2] and Mitchell[8] each utilize most of the suggestions above. Fast DES implementations also use similar techniques[4] Speed crypt has a technique for the E expansion that can double the speed of an implementation on 32 bit RISC machines. The questor code was written by Donald Mitchell at Bell Labs and is ....
....also use similar techniques[4] Speed crypt has a technique for the E expansion that can double the speed of an implementation on 32 bit RISC machines. The questor code was written by Donald Mitchell at Bell Labs and is probably the most straight forward of the fast crypt implementations[8]. Subkey generation uses two table lookups (Permuted Choice i and Permuted Choice 2) and two rotations per subkey. The E expansion is done as eight 64 bit table lookups (4 bits of R at a time) The S function 18 in the delta bitmap. This delta bitmap is then exclusive ORed with bits 1 12 and ....
