Lightweight cryptography is a rapidly developing research field. Its main goal is to provide
security for devices with fewer resources. These limited‐resource devices implement …

A new version of the stream cipher Grain-128 is proposed. The new version, Grain-128a, is
strengthened against all known attacks and observations on the original Grain-128, and has …

We present a new variant of cube attacks called a dynamic cube attack. Whereas standard
cube attacks [4] find the key by solving a system of linear equations in the key bits, the new …

The need for lightweight (that is, compact, low-power, low-energy) cryptographic hash
functions has been repeatedly expressed by professionals, notably to implement …

The need for lightweight cryptographic hash functions has been repeatedly expressed by
application designers, notably for implementing RFID protocols. However not many designs …

A chaotic system and two Nonlinear Feadback Shift Registers (NFSRs) are used to generate
a new stream cipher in this paper. This design can be used for efficient encryption in …

In this paper we study a differential fault attack against the Grain family of stream ciphers.
The attack works due to certain properties of the Boolean functions and corresponding …

In Fast Software Encryption (FSE) 2015, while presenting a new idea (ie, the design of
stream ciphers with the small internal state by using a secret key, not only in the initialization …

The way address sequences and data patterns appear on the outside of a memory may
differ from their internal appearance; this effect is referred to as scrambling, which has a …

In this paper we describe the first single-key attack which can recover the full key of the full
version of Grain-128 for arbitrary keys by an algorithm which is significantly faster than …
