Hierarchical ID-Based Cryptography

Craig Gentry and Alice Silverberg

Abstract

We present hierarchical identity-based encryption schemes and signature schemes that have total collusion resistance on an arbitrary number of levels and that have chosen ciphertext security in the random oracle model assuming the difficulty of the Bilinear Diffie-Hellman problem.
