Hierarchical Identity-based Broadcast Encryption Scheme on Lattices
2011 Seventh International Conference on Computational Intelligence and Security, 2011 In this paper, a hierarchical identity-based broadcast encryption scheme is proposed based on the learning with errors problem, which is a classic hard problem on lattices. In the proposed scheme, each user's identity is associated with a lattice matrix, then the relationship between the lattice and its sub lattice could easily represent the ...

Anonymous Hierarchical Identity-Based Encryption with Short Ciphertexts
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011 We propose an anonymous Hierarchical Identity-Based Encryption (anonymous HIBE) scheme with short ciphertexts. Prior to our work, most anonymous HIBE schemes have long ciphertexts increased according to the hierarchical depth of recipient. The size of the ciphertext in our scheme does not depend on the depth of the hierarchy.

Anonymous Hierarchical Identity-based Encryption EHR Sharing Mechanism Based on SM9
2022 IEEE 21st International Conference on Ubiquitous Computing and Communications (IUCC/CIT/DSCI/SmartCNS), 2022The identity-based encryption (IBE) scheme SM9 is a commercial encryption standard in China and has been used as a basic building block for authentication. Currently, to accommodate large-scale application scenarios, a variant hierarchical identity-based
