Improved security proofs of Delerablée's identity-based broadcast encryption scheme
Pages 472 - 481
Abstract
Delerablée proposed the first identity-based broadcast encryption scheme with constant size ciphertexts and private keys in [7]. But, the scheme was proved to be secure in the selective identity security model. We prove the scheme is secure in the full security model under an interactive assumption.

On the security of a strong provably secure identity-based encryption scheme without bilinear pairing
The identity-based encryption scheme enables a sender to generate the ciphertext using a receiver's identity and system's parameters. Because of its convenience, the identity-based encryption scheme has been widely used in many practical applications. ...

ASIA CCS '16: Proceedings of the 11th ACM on Asia Conference on Computer and Communications SecurityIn this paper, we present the notion of recipient-revocable identity-based broadcast encryption scheme. In this notion, a content provider will produce encrypted content and send them to a third party (which is a broadcaster). This third party will be ...
