Cryptography and Information Security in the Balkans

This book contains revised selected papers from the Second International Conference on Cryptology and Information Security in the Balkans, BalkanCryptSec 2015, held in Koper, Slovenia, in September 2015. The 12 papers presented in this volume were carefully reviewed and selected from 27 submissions. They are organized in topical sections named: symmetric key cryptography; cryptanalysis; security and protocols; and implementation and verifiable encryption.
