This paper presents a high-throughput multiple-input multiple-output (MIMO) signal detector based on the sort-free concept and the proposed mean-aided early-pruned scheme. The derived MIMO detector can reduce the number of node computation while maintaining the bit error rate (BER) performance of the conventional sort-free MIMO detection algorithm. Experimental results show that the proposed detector...
There has been high demand for low power and area efficient implementation of complex arithmetic operations in many digital signal processing applications. The CORDIC (coordinate rotation digital computer) algorithm is a unique technique for performing various complex arithmetic functions using shift-add iterations. This paper proposes an enhanced version of new CORDIC algorithm (obtained from conventional...
Salsa20 is a stream cipher candidate in the software-oriented profile of the eSTREAM project. ChaCha is a successor stream cipher with improved per round diffusion and, conjecturally, increased resistance to cryptanalysis. Based on the combination of four Salsa20 instances, Rumba is a compression function for hashing schemes. This paper presents the evaluation of five VLSI circuits for Salsa20. Synthesis...
This paper proposes an AES algorithm against both differential power analysis and differential fault analysis and its hardware implementation. This new algorithm emphasizes the feature of defending hardware against two kinds of side-channel attack simultaneously. Since the modified AES algorithm is much more complex than the original one, this paper exploits low hardware cost architecture to realize...
