This paper presents a reconfigurable architecture of the Advanced Encryption Standard (AES-Rijndael) cryptosystem. The suggested reconfigurable architecture is capable of handling all possible combinations of standard bit lengths (128, 192, 256) of data and key. The fully rolled inner-pipelined architecture ensures lesser hardware complexity. The work(More)
The paper puts forward the design of an intelligent SHA-1 based crypto system. For a given 512-bit message stream the intelligence of the system lies in its power of predicting the probable-colluders. Along with the conventional SHA-1 architecture, our scheme employs a predictor control block which takes the message stream from the user, and provides the(More)
