Cryptographic Application of Elliptic Curve with High Rank
Xiaogang Cheng, Ren Guo, Zuxi Chen
Elliptic curve cryptography is better than traditional cryptography based on RSA and discrete logarithm of finite field in terms of efficiency and security. In this paper, we show…
Enhanced Security of Public Key Encryption with Certified Deletion
Xiaogang Cheng, Ren Guo
In classical cryptography, certified deletion is simply impossible. Since classical information can be copied any number of times easily. In quantum cryptography, certified deletio…
Research on Data Right Confirmation Mechanism of Federated Learning based on Blockchain
Xiaogang Cheng, Ren Guo
Federated learning can solve the privacy protection problem in distributed data mining and machine learning, and how to protect the ownership, use and income rights of all parties…
Concept and Construction of Group Signature with self-proof capacity for confirming and denying
Xiaogang Cheng, Ren Guo
With privacy-preserving and traceability properties, group signature is a cryptosystem with central role in cryptography. And there are lots of application scenarios. A new extensi…
