Inner Product Masking Revisited
Masking is a popular countermeasure against side channel attacks. Many practical works use Boolean masking because of its simplicity, ease of implementation and comparably low performance overhead. Some recent works have explored masking schemes with higher algebraic complexity and have shown that they provide more security than Boolean masking at the cost of higher overheads. In particular, ma...
متن کاملFault Masking in Tri-redundant Systems
A tri-redundant version of a system S is a system T that is specified from S as follows. First, system T has the same number of processes and the same topology as system S. Second, each variable x in a process in system S is replaced by three variables x, x′, and x′′ in the corresponding process in system T . Third, the actions in each process in system S are modified before they are added to t...
متن کاملLow Entropy Masking Schemes, Revisited
Low Entropy Masking Schemes (LEMS) are a recent countermeasure against side-channel attacks. They aim at reducing the randomness requirements of masking schemes under certain (adversarial and implementation) conditions. Previous works have put forward the interest of this approach when such conditions are met. We complement these investigations by analyzing LEMS against adversaries and implemen...
متن کاملCode Duality Revisited
In 1991 Claus Emmeche and I suggested that ‘the chain of events which sets life apart from non-life.... needs at least two codes: one code for action (behaviour) and one code for memory—the very first of these codes necessarily must be analog and the second very probably must be digital.’ This principle of code-duality played a major role in our initial ideas on biosemiotics. The paper looks ba...
متن کاملASIC Design of Butterfly Unit Based on Non-Redundant and Redundant Algorithm
Fast Fourier Transform (FFT) processors employed with pipeline architecture consist of series of Processing Elements (PE) or Butterfly Units (BU). BU or PE of FFT performs multiplication and addition on complex numbers. This paper proposes a single BU to compute radix-2, 8 point FFT in the time domain as well as frequency domain by replacing a series of PEs. This BU comprises of fused floating ...
