WebJun 1, 2016 · Efficient Adaptively Secure IBBE From the SXDH Assumption. Abstract: This paper describes the first constructions of identity-based broadcast encryption (IBBE) … WebWe present efficient Identity-Based Encryption (IBE) and signature schemes under the Symmetric External Diffie-Hellman (SXDH) assumption in bilinear groups. In both the IBE and the signature schemes, all parameters have constant numbers of group elements, and are shorter than those of previous constructions based on Decisional Linear (DLIN) …

Since their introduction, lossy trapdoor functions have found numerous applications. They can be used as tools to construct important cryptographic primitives such as injective one-way trapdoor functions, chosen-ciphertext-secure public key encryptions, deterministic … bise rawalpindi 10 class result 2021
