Abstract

We offer an alternative Public Key Broadcast Encryption (PKBE) scheme which is fully collusion-secure. Our construction is based on the method for generating private keys in the Boneh, Boyen and Goh's hierarchical identity-based encryption scheme. Our scheme provides a trade-off between ciphertext size and public key size. With appropriate parametrization we achieve a PKBE scheme where both ciphertexts and private keys are sublinear size for any subset of receivers. Private keys shrink as revoked users increase, and public key size is more reduced than other PKBE schemes. We extend our scheme to obtain chosen ciphertext security by using hash-based method.
