DESIGN FOR FAST STREAM CIPHER ASC16

摘要

PURPOSE: it designs quick stream cipher ASC 16 and is provided to improve the performance and speed of software and hardware. ;CONSTITUTION: stream cipher ASC16 includes arithmetic shift register, nonlinear block, nonlinear block generation filter. The arithmetic shift register is by 151 and 5 words. Final decision-making authority uses only 23. Non-linear piece generator by 16 words, and generates non-linear piece using two pointer parameter, these parameters are the PG (point) generated by generator. Non-linear piece generator generates the word between 32 defeated 3 using two words from arithmetic shift register and 16 words, from non-linear piece generator. ;The 2011 of copyright KIPO submissions
