January 17, 2018 FAME: Fast Attribute-based Message Encryption

Speaker:  Shashank Agrawal

Abstract:  Time and again, attribute-based encryption has been shown to be the natural cryptographic tool for building various types of conditional access systems with far-reaching applications, but the deployment of such systems has been very slow. A central issue is the lack of an encryption scheme that can operate on sensitive data very efficiently and, at the same time, provides features that are important in practice. In this talk I will present the first fully secure ciphertext-policy and key-policy ABE schemes based on a standard assumption on Type-III pairing groups, which do not put any restriction on policy type or attributes. The schemes are implemented along with several other prominent ones using the Charm library, and perform better on almost all parameters of interest.
