Title
Universally Composable Symmetric Encryption
Abstract
For most basic cryptographic tasks, such as public-key encryption, digital signatures, authentication, key exchange, and many other more sophisticated tasks, ideal functionalities have been formulated in the simulation-based security approach, along with their realizations. Surprisingly, however, no such functionality exists for symmetric encryption, except for a more abstract Dolev-Yao style functionality. In this paper, we fill this gap. We propose two functionalities for symmetric encryption, an unauthenticated and an authenticated version, and show that they can be implemented based on standard cryptographic assumptions for symmetric encryption schemes, namely IND-CCA security and authenticated encryption, respectively, provided that the environment does not create key cycles or cause these-called commitment problem. We also illustrate the usefulness of our functionalities in applications, both in simulation-based and game-based security settings.
