ePrint Report: Committing authenticated encryption based on SHAKE

Joan Daemen, Silvia Mella, Gilles Van Assche

Authenticated encryption is a cryptographic mechanism that allows communicating parties to protect the confidentiality and integrity of message exchanged over a public channel, provided they share a secret key. Some applications require committing authenticated encryption schemes, a security notion that is not covered by the classical requirements of confidentiality and integrity given a secret key. An authenticated encryption (AE) scheme is committing in the strongest …
