Matthew Beighton · Queensland University of Technology · 2022
Society's thirst for smaller, faster and more complex technology requires highly secure cryptosystems. These systems are under constant pressure to evolve higher levels of security integrated within ever-shrinking, highly complex hardware, with minimal runtime costs. These demands have focused attention on the design of lightweight cryptographic algorithms because of their speed. The research presented in this thesis focuses on the design and security analysis of lightweight stream ciphers capable of authenticated encryption with associated data (AEAD), proposed as part of the National Institute of Standards and Technology's (NIST) lightweight cryptography competition.
