[oc] (Cryptography) : AES TwoFish




 Hi all,

 	We are also interested in cryptography, our interest is AES 
	(Advanced Ecryption Standard) which is planned to substitute DES
	as encryption standard.

 	From all of top 5 finalists we are interested in MARS and TwoFish.
  	Between those two, my friend (Irwanto Mursetiono) and I will
 	design TwoFish core which may be useful in encryption processing.

	We've tried to contact one of the author of TwoFish , Bruce Schneier,
	to get permission to use TwoFish to be published and developed in
	this community. (although in www.counterpane.com/twofish we can 
 	download the source freely)
 	and I quote his reply as follow:
	...Twofish is unpatented and freely available for use.
 	
	FYI TwoFish is a 128-bit block cipher algorithm that can encrypt
	plaintext up to 256-bit key to ciphertext. About speed, different
	hardware implementation give different result.
	It's just like you put triple DES to encrypt messages at the exact
	time 1 DES can spent
 	
  	We will use verilog and alliance tools to design and analyze
 	encryption processor, the word processor here is refer to
 	encrypt/decrypt.
 
 	About specs we adopt from another topic in cryptography cores
 	(afterall if we keep this core open we must accept all possible
	ideas, right Damjan?)
	But our first target is to make behavioral an structural design of
	this core.
	 	
	so, what do you think guys?	
 
...AUL...
