Cryptographic methods have been extensively employed in various systems to address
security objectives, such as data confidentiality, authentication, and secure communication …

In response to side-channel attacks on masked implementations of post-quantum
cryptographic algorithms, a new bitsliced higher-order masked implementation of …

In this paper, we present the first chosen-ciphertext (CC) cache-timing attacks on the
reference implementation of HQC. We build a cache-timing based distinguisher for …

Although cryptographic algorithms may be mathematically secure, it is often possible to leak
secret information from the implementation of the algorithms. Timing and power side …

Last year CRYSTALS-Kyber was chosen by NIST as a new, post-quantum secure key
encapsulation mechanism to be standardized. This makes it important to assess the …

Significant advancements have been achieved in the field of quantum computing in recent
years. If somebody ever creates a sufficiently strong quantum computer, many of the public …

We uncover a critical side-channel vulnerability in the Hamming Quasi-Cyclic (HQC) round 4
optimized implementation arising due to the use of the modulo operator. In some cases …

In response to side-channel attacks on masked implementations of post-quantum
cryptographic algorithms, a new bitsliced higher-order masked implementation of …

The McEliece cryptosystem is a strong contender for post-quantum schemes, including key
encapsulation for confidentiality of key exchanges in network protocols. A McEliece secret …

In this research, side-channel analysis attacks against the Krystal Kyber cryptographic
scheme are empirically studied. This study explores how vulnerable Krystal Kyber is to these …
