Cryptography and Coding

This book constitutes the proceedings of the 17th IMA International Conference on Cryptography and Coding, IMACC 2019, held in Oxford, UK, in December 2019. The 17 papers presented were carefully reviewed and selected from 31 submissions. The conference focuses on a diverse set of topics both in cryptography and coding theory.
