Discrete logarithmic pseudorandom number generators are a prevailing class of
cryptographically-secure pseudorandom number generators (CSPRNGs). In generators of …

This paper presents an efficient solution to reduce the power consumption of the popular
linear feedback shift register by exploiting the gated clock approach. The power reduction …

The elementary cellular automata (ECAs) under the chaotic rule possess long periodicity
and are widely used in pseudo-random number generators. However, their period is limited …

Many security-related scenarios including cryptography depend on the random generation
of passwords, permutations, Latin squares, CAPTCHAs and other types of non-numerical …

Perfectly-secure cryptography is a branch of information-theoretic cryptography. A perfectly-
secure cryptosystem guarantees that the malicious third party cannot guess anything …

In this chapter, we have studied three word-oriented stream ciphers SNOW 1.0, SNOW 2.0
and SNOW 3G in a detailed way. The detailed description includes the working principles of …

In LFSR-based stream ciphers, the knowledge of the feedback equation of the LFSR plays a
critical role in most attacks. In word-based stream ciphers such as those in the SNOW series …

This paper deals with an updated SNOW 3G key stream generator (KSG). The proposed
KSG can be applied to encrypt images in the Internet of Things (IoT) applications. The KSG …

In LFSR-based stream ciphers, the knowledge of the feedback equation of the LFSR plays a
critical role in most attacks. In word-based stream ciphers such as those in the SNOW series …

Aiming at the security problem of English private data in a cloud environment, this paper
puts forward a novel homomorphic encryption and k-center algorithm for the secure storage …
