A Chosen Plaintext Attack on Offset Public Permutation Mode

Miloslav Homer

Abstract

Offset Public Permutation Mode (OPP) by Granger et al. is a one-pass authenticated encryption scheme supporting associated data (AEAD scheme). Leveraging an error in analysis of the scheme, a chosen plaintext attack that creates a forgery was discovered. This attack makes no assumptions about the underlying tweakable blockcipher while having negligible complexity requirements and high probability of success. An implementation of the attack is also provided.
