Secure multi-gigabit optical link design for high energy physics experiment with acceleration of more secure RC4 variant in reconfigurable platform R. Paul, J. Mitra, H. Dey, S. Sau, P. Baidya, R. Ghosh, A. Chakrabrti Journal of Instrumentation, 2020 Many cryptographic attacks are capable to break RC4. Still RC4 becomes alive in crypto community with several variants. Insufficient key schedule is the most important weakness of RC4 where the first bytes of output reveals information about the key. The loop-holes can be corrected by discarding initial portion of the output stream [1] which is known as RC4-dropN (N is a multiple of 256, such as 768 or 1024). Here we shows RC4 can be made more secured if an additional RC4-like Post-KSA Random Shuffling (PKRS) process is introduced between KSA and PRGA. The PKRS process is tuned to form as many S-boxes as required by particular design architectures involving multiple coprocessors, each one undertaking byte-by-byte processing. Following a recent idea [2, 3] the speed of execution of each processor is also enhanced by another fold if the byte-bybyte processing is replaced by a scheme of processing two consecutive bytes together. Adopting some new innovative concepts, three hardware design architectures are proposed in a suitable FPGA embedded system involving 1, 2 and 4 coprocessors functioning in parallel and a study is made on accelerating RC4 by processing bytes in byte-by-byte mode achieving throughputs from l.-byte-in-1 -clock to 4-bytes-in- 1-clock. The hardware designs are appropriately upgraded to accelerate RC4 further by processing 2 consecutive RC4 bytes together and it has been possible to achieve a maximum throughput of 8-bytes per clock in Xilinx Virtex-5 LX110t FPGA [4] architecture followed by secured communication High Energy Physics (HEP) application that preserves the DC-balancing of the link and permits forward error correction (FEC) along with encryption.
An approach to assess the optimality of refining RC4 Suman Das, Hemanta Dey, Ranjan Ghosh Proceedings of the 2015 3rd International Conference on Computer Communication Control and Information Technology C3it 2015, 2015 Though RC4 has proved itself as a simple, fast and robust stream cipher and it is trusted by many organizations, a number of researchers claimed that RC4 has some weakness and bias in its internal states. To increase its security, some guidelines recommended discarding some initial bytes like N, 2N or more from the RC4 key-stream (N is 256, generally). In this paper, the authors tried to find out the optimum number of bytes that is to be discarded to have a more secured RC4, by analyzing some variants of it. All the algorithms, including the original one, are analyzed by the NIST Statistical Test Suite and it has been found that it is not necessary discarding more and more number of bytes to increase the security of RC4.
New simulation toolkit for comparison of scheduling algorithm on cloud computing Soumen Santra, Hemanta Dey, Sarasij Majumdar, Gauri Shankar Jha 2014 International Conference on Control Instrumentation Communication and Computational Technologies Iccicct 2014, 2014 New simulation toolkit for comparison of scheduling algorithm on cloud computing provides reliable, customized and guaranteed dynamic computing environments for end-users in such a way so that more and more people tend to adapt the cloud environment in their workplace. Cloud computing is becoming an increasingly popular enterprise model in which computing resources are made available on-demand to the user as required. The unique concept of cloud computing creates new opportunities to align Business and IT goals. Job scheduling is an essential requirement in cloud computing environment with the given constraints. Some intensive researches have been done in the area of job scheduling of cloud computing. The scheduling algorithms should order the jobs in a way where balance between improving the performance and quality of service and at the same time maintaining the efficiency and fairness among the jobs. This paper aims at studying various scheduling algorithms recently proposed in cloud computing.
