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)
This paper puts forward an efficient and optimized method to determine the probable-colluders in a MD5 based cryptosystem. Along with the conventional MD5 implementing architecture, our scheme employs a predictor control block which takes the message stream from the user, and provides the log-list of the equal length bit-streams that are most likely to(More)
This paper proposes a novel scheme of Fuzzy Logic based dynamic routing in computer networks. The proposed dynamic routing algorithm is suited for application in Interior Gateway Protocols (IGP) inside an autonomous system (AS), such as a Local Area Networks (LAN). It is used in the protocols to find out a set of best possible routes, where each of the(More)
