This book constitutes the refereed proceedings of the 10th International Conference on Information Theoretic Security, ICITS 2017, held in Hong Kong, China, in November/December 2017.The 12 full papers were carefully reviewed and selected from 42 submissions. They are organized around the following topics: quantum cryptography; quantum information theory; post-quantum cryptography (e.g. lattices and cryptography); physical layer security; wiretap channels; adversarial channel models; cryptography from noisy channels; bounded storage models; network coding security; biometric security; randomness extraction; key and message rates; secret sharing; authentication codes; multiparty computations; information theoretic reductions; and implementation challenges.
