PDF-Cryptographic Shuing of Random and Pseudorandom Sequences Markus Dichtl Siemens Corporate

Dichtlsiemenscom Abstract This papers studies methods to improve the cryptographic quality of random or pseudorandom sequences by modifying the order of the original sequence A new algorithm Cryshu is suggested which produces its shu64260ed output da. uoagr Abstract Pseudorandom sequences have many applications in cryp tography and spread spectrum communications In this dissertation on one hand we develop tools for assessing the randomness of a sequence and on the other hand we propose new constru Dan Fleck.
