		abstract={Triple DES is also known as TDES or, more standard, TDEA (Triple Data    
 
 
 

Encryption Algorithm [1]). The non-standard convention to use DES (standard) when we    
 
 
 

actually mean DEA (algorithm) is so widespread that in order to avoid confusion we use    
 
 
 

it in this article. On the other hand, since there are variations of TDES which use two    
 
 
 

different keys (2TDES) and three different keys (3TDES) the non-standard abbreviation    
 
 
 

3DES is confusing and should be avoided.    
 
 
 

The cipher is a 16-round Feistel network with a bijective F function made up of    
 
 
 

four key-dependent 8-by-8-bit S-boxes, a fixed 4-by-4 maximum distance separable    
 
 
 

matrix over GF(28), a pseudo-Hadamard transform, bitwise rotations, and a carefully    
 
 
 

designed key schedule. A fully optimized implementation of Twofish encrypts on a    
 
 
 

Pentium Pro at 17.8 clock cycles per byte, and an 8-bit smart card implementation    
 
 
 

encrypts at 1820 clock cycles per byte. Twofish can be implemented in hardware in    
 
 
 

14000 gates. The design of both the round function and the key schedule permits a wide    
 
 
 

variety of tradeoffs between speed, software size, key setup time, gate count, and    
 
 
 

memory. We have extensively cryptanalyzed Twofish; our best attack breaks 5 rounds    
 
 
 

with 222,5 chosen plaintexts and 251 effort.}
