Lattice-based cryptography has been proposed as a postquantum public-key cryptosystem.
In this paper, we present a masked ring-LWE decryption implementation resistant to first …

Reducing the entropy of the mask is a technique which has been proposed to mitigate the
high performance overhead of masked software implementations of symmetric block …

In this paper, we propose a masking scheme to protect ring-LWE decryption from first-order
side-channel attacks. In an unprotected ring-LWE decryption, the recovered plaintext is …

The problem of extracting the highest possible amount of key-related information using the
lowest possible number of measurements is one of the central questions in side-channel …

The literature on side-channel analysis describes numerous masking schemes designed to
protect block ciphers at the implementation level. Such masking schemes typically require …

Naïve implementation of block ciphers are subject to side-channel and fault injection attacks.
To deceive side-channel attacks and to detect fault injection attacks, the designer inserts …

A highly efficient and power analysis attack robust architecture for hardware implementation
of the advanced encryption standard algorithm (AES) is presented. By choosing a correct …

Masking schemes based on tables recomputation are classical countermeasures against
high-order side-channel attacks. Still, they are known to be attackable at order d in the case …

Masking is the best-researched countermeasure against side-channel analysis attacks.
Even though masking was introduced almost 20 years ago, its efficient implementation …

Abstract The Advanced Encryption Standard (AES) is a 128-bit block cipher that is currently
being widely used in smartcards. Differential Power Analysis (DPA) is a powerful technique …
