摘要:This paper attempts to develop a simple, stronger and safer cryptographic algorithm which would not only be a secure one, but also reduces total time taken for encryption and decryption. The result of such an attempt is “Blow-CAST-Fish”, a new secret-key block cipher that uses good features of CAST-128 and Blowfish algorithms. An effort is made to enhance performance of the resulting algorithm by parallel evaluation of some operations within the round function. In order to show the reduction in execution time, VHDL implementation is used and tested to show percentage improvement in the performance of the modified Blow-CAST-Fish.
