Abstract
Hierarchical ID-based Cryptography proposed by C. Gentry and A. Silverberg has the problem that the length of the ciphertext is proportional to the depth of the recipient in the hierarchy. In this paper, we propose the new methods to shorten the length of the ciphertext by using HlDS(Hierarchical ID-based Signature).
