Cryptography and Network Security in high speed networks demands for specializedhardware in order to match up with the network speed. These hardwaremodules are being realized using reconfigurable FPGA technology to supportheavy computation. Our work is mainly based on designing an efficient architecturefor a cryptographic module and a network intrusion detection system for ahigh speed network. All the designs are coded using VHDL and are synthesizedusing Xilinx ISE for verifying their functionality. Virtex II pro FPGA is chosenas the target device for realization of the proposed design. The...

Real time distributed systems (RTDS) operate in an environment that un- dergoes unpredictable changes causing certain system performance features to degrade. Such unpredictability can be the result of sudden machine failures, in- creases in system load, or errors caused by inaccurate initial estimation. These systems need robustness to guarantee limited degradation despite uctuations in the behavior of its component parts or environment. The robustness gives an idea of the stability of the solution with regards to another performance metric such as schedule length, load balance of an...
