Masking is one of the most popular countermeasures to protect cryptographic implementations against side-channel analysis since it provably secure and can be deployed at algorithm level. To strengthen original Boolean masking scheme, several works have suggested using schemes with high algebraic complexity. The Inner Product (IPM) those. In this paper, we propose a unified framework quantitativ...

In this paper, the intra residual macroblock produced by H.264 is investigated. Based on its characteristics, an efficient two-layer coding scheme for the intra residual macroblock is developed. The rate-distortion performance for the proposed coding scheme is evaluated. Experimental results show that our algorithm can achieve better coding performance.

This paper proposes a principled extension of the traditional single-layer flat sparse coding scheme, where a two-layer coding scheme is derived based on theoretical analysis of nonlinear functional approximation that extends recent results for local coordinate coding. The two-layer approach can be easily generalized to deeper structures in a hierarchical multiple-layer manner. Empirically, it ...

Abstract—Network coding in wireless network can improve network throughput by exploiting the broadcast nature of the wireless network. Taking into consideration the error prone nature of wireless networks, we investigate the design of network coding implemented in physical layer, and propose a cooperative network codi...
