Design and Cryptanalysis of ZUC : A Stream Cipher in Mobile Telephony

This book is a timely document of state-of-the art analytical techniques in the domain of stream cipher design and analysis with a specific cipher, named ZUC. It links new research to brief contextual literature review in the domain of complex LFSR-based stream ciphers. A snapshot of how stream ciphers are deployed in the mobile telephony architecture, one of the most well-known topics for more than five decades in the domain of computer and communication sciences, is presented in this book. The book provides an in-depth study on design and cryptanalysis of ZUC as well as relevant research results in this field with directions towards future analysis of this cipher.

CHANDRA SEKHAR MUKHERJEE is a postgraduate student of computer science at the Indian Statistical Institute, Kolkata, India. He received his undergraduate degree in computer science from Heritage Institute of Technology, Kolkata, India, in 2019. He got introduced to theoretical computer science during his pre-final year of undergraduate studies after which he explored the areas of computational geometry and graph algorithms. His inclination towards finding patterns within random behavior of objects got him attracted to combinatorial algorithms and number theory. The deep connection between probability, combinatorics and number theory which leads to the fine line between randomness and bias deeply intrigued him in the domain of cryptology. His current areas of research include cryptology and quantum information theory. Being in the formative years of his research career, he wishes to meaningfully contribute to the broad area of secure communication.
