Title:
Fully Secure Anonymous Hierarchical Identity-Based Encryption with Constant Size Ciphertexts

Authors: Jae Hong Seo, Jung Hee Cheon

Abstract:

Efficient and privacy-preserving constructions for search functionality on encrypted data is important issues for data outsourcing, and data retrieval, etc. Fully secure anonymous Hierarchical ID-Based Encryption (HIBE) schemes is useful primitives that can be applicable to searchable encryptions [4], such as ID-based searchable encryption, temporary searchable encryption [1], and anonymous forward secure HIBE [9]. We propose a fully secure anonymous HIBE scheme with constant size ciphertexts.
