Linear feedback shift registers (LFSRs) and nonlinear feedback shift registers (NLFSRs) are major components of stream ciphers. It has been shown that, under certain idealized assumptions, LFSRs and LFSR-based stream ciphers are susceptible to cryptanalysis using simple power analysis (SPA). In this paper, we show that simple power analysis can be(More)
Since 1976, when the principles of public key cryptography were introduced (by Whitfield Diffie and Martin Hellman) (Diffie & Hellman 1976), RSA was the most well-known public key cryptographic system. Rivest, Shamir and Adleman (RSA) algorithm composes a public key considered sufficiently long enough to be recognized as secure. The security of RSA is based(More)
In this paper a new approach for multipliers over GF(2<sup>m</sup>) in polynomial (standard) basis representation is proposed. The proposed multiplier is a new construction for hybrid multipliers. The main advantage of this multiplier compare to other proposed multipliers is in the reduction unit which occupies less area on chip to implement. In this(More)
Power analysis has come to be an important category of cryptanalytic attacks. Although such attacks have been extensively applied to block ciphers, only limited research has been done to analyze their effectiveness on stream cipher hardware implementations. In this paper, we consider the application of simple power analysis (SPA) to the Grain stream cipher.(More)
In recent years, the hardware implementation of stream ciphers has attracted the interest of many designers, mainly due to their low implementation area on a chip. However, to date, in comparison with block ciphers, side channel attacks have not been extensively analyzed for their applicability to stream cipher hardware implementations. However it has been(More)
