A popular cryptographic option to implement Hierarchical Access Control in organizations is to combine a key assignment scheme with a symmetric encryption scheme. In brief, key assignment associates with each object in the hierarchy a unique symmetri

The Authenticated Encryption with Associated Data (AEAD) primitive, which integrates confidentiality and integrity services under a single roof, found wide-spread adoption in industry and became indispensable in practical protocol design. Recognizing

This paper closes a definitional gap in the context of modeling cryptographic two-party channels. We note that, while most security models for channels consider exclusively unidirectional communication, real-world protocols like TLS and SSH are rathe

This work introduces Algorithm Substitution Attacks (ASAs) on message authentication schemes. In light of revelations concerning mass surveillance, ASAs were initially introduced by Bellare, Paterson and Rogaway as a novel attack class against the co

Roughly four decades ago, Taher ElGamal put forward what is today one of the most widely known and best understood public key encryption schemes. ElGamal encryption has been used in many different contexts, chiefly among them by the OpenPGP email enc

This work describes a class of Algorithm Substitution Attack (ASA) generically targeting the receiver of a communication between two parties. Our work provides a unified framework that applies to any scheme where a secret key is held by the receiver;
