Efficient Broadcast Encryption Scheme with Log-Key Storage
In this paper, we present a broadcast encryption scheme with efficient transmission cost under the log-key restriction. Given n users and r revoked users, our scheme has the trans...

Efficient Broadcast Encryption Using Multiple Interpolation Methods
We propose a new broadcast encryption scheme based on polynomial interpolations. Our scheme, obtained from the Naor-Pinkas scheme by partitioning the user set and interpolating mul...

Efficient Chosen Ciphertext Secure Public Key Encryption under the Computational Diffie-Hellman Assumption
Recently Cash, Kiltz, and Shoup [20] showed a variant of the Cramer-Shoup (CS) public key encryption (PKE) scheme [21] whose chosen-ciphertext (CCA) security relies on the computa...
