Abstract Authenticated encryption satisfies the basic need for authenticity and confidentiality in our information infrastructure. In this paper, we provide specification of Ascon -128 -128a. Both authenticated algorithms efficient on resource-constrained devices high-end CPUs. Furthermore, they have been selected as “primary choice” lightweight final portfolio CAESAR competition. addition, spe...

Secure and authenticated message delivery/storage is one of the major aims of computer and communication security research. The current standard method to achieve this aim is \(digital) signature followed by encryption". In this paper, we address a question on the cost of secure and authenticated message delivery/storage, namely, whether it is possible to transport/store messages of varying len...

When using an authenticated-encryption scheme (a shared-key mechanism that provides both privacy and authenticity) it is sometimes useful, when encrypting a message, to also authenticate some additional information which is not privacy protected. We address this associateddata problem, wherein a Sender can bind to an authenticated ciphertext C a string AD, called its associated-data, and where ...

This document describes an additional content type for the Cryptographic Message Syntax (CMS) [CMS]. The authenticatedenveloped-data content type is intended for use with authenticated encryption modes, where an arbitrary content is both authenticated and encrypted. Also, some associated data in the form of authenticated attributes can also be authenticated. All of the various key management te...
