Quantum computing is considered among the next big leaps in computer science. While a
fully functional quantum computer is still in the future, there is an ever-growing need to …

With the advancement of the quantum computing technologies, a large body of research
work is dedicated to revisit the security claims for ciphers being used. An adversary with …

In this paper, we present the quantum implementation and analysis of the recently proposed
block cipher, DEFAULT. This cipher consists of two components, namely DEFAULT-LAYER …

Secure communication is important for Internet of Things (IoT) applications, to avoid cyber-
security attacks. One of the key security aspects is data integrity, which can be protected by …

This article presents the cost analysis of mounting Grover's key search attack on the family of
KATAN block cipher. Several designs of the reversible quantum circuit of KATAN are …

The security level of a cipher is a key parameter. While general-purpose quantum computers
significantly threaten modern symmetric ciphers, other quantum approaches like quantum …

Abstract The National Institute of Standards and Technology (NIST) initiated a public
standardization process to select one or more schemes that provide Authenticated …

In this work, we have analyzed ChaCha against Grover's search algorithm. We designed a
reversible quantum circuit of ChaCha and then estimated the resources required to …

The development of quantum computers, which employ a different paradigm of computation,
is posing a threat to the security of cryptography. Narrowing down the scope to symmetric …

The recent developments in the creation of large-scale, commercially feasible quantum
computers puts both symmetric and asymmetric encryption at risk. As they assess the …
