This book constitutes the refereed proceedings of the 9th International Workshop on Security, IWSEC 2014, held in Hirosaki, Japan, in August 2014. The 13 regular papers presented together with 8 short papers in this volume were carefully reviewed and selected from 55 submissions. The focus of the workshop was on the following topics: system security, threshold cryptography, hardware security, foundation, and encryption.
