Self-Bilinear Map from One Way Encoding System and iđť’Ş
InformationA bilinear map whose domain and target sets are identical is called a self-bilinear map. Original self-bilinear maps are defined over cyclic groups. Since the map itself reveals information about the underlying cyclic group, the Decisional Diffie–Hellman

PLoS ONE, 2018 Fog computing can extend cloud computing to the edge of the network so as to reduce latency and network congestion. However, existing encryption schemes were rarely used in fog environment, resulting in high computational and storage overhead.

Identity-based key-insulated aggregate signature scheme
Journal of King Saud University: Computer and Information Sciences, 2017 Private key exposure can be the most devastating attack on cryptographic schemes; as such exposure leads to the breakage of security of the scheme as a whole. In the real world scenario, this problem is perhaps the biggest threat to cryptography.

New Techniques for SIDH-based NIKE
Journal of Mathematical Cryptology, 2020 We consider the problem of producing an efficient, practical, quantum-resistant non-interactive key exchange (NIKE) protocol based on Supersingular Isogeny Diffie-Hellman (SIDH).

The Twin Bilinear Diffie-Hellman Inversion Problem and Applications
, 2011 We propose a new computational problem and call it the twin bilinear Diffie-Hellman inversion (BDHI) problem. Inspired by the technique proposed by Cash, Kiltz and Shoup, we have developed a new trapdoor test which enables us to prove that the twin BDHI ...

Revocable Identity-Based Encryption and Server-Aided Revocable IBE from the Computational Diffie-Hellman Assumption [PDF]
, 2018 An Identity-based encryption (IBE) simplifies key management by taking users’ identities as public keys. However, how to dynamically revoke users in an IBE scheme is not a trivial problem.

Anonymous Fingerprinting as Secure as the Bilinear Diffie-Hellman Assumption [PDF]
, 2002 The illegal copying and redistribution of digitally-stored information is a crucial problem to distributors who electronically sell digital data. Fingerprinting provides a means which a copyright owner can trace illegal redistributors of electronic ...
