A PKI-based Asymmetric Self-enforcement Traitor Tracing Scheme with Public-key;

Based on detection method of weak square signal in strong noise with a chaotic oscillator,a public-key robust watermarking scheme is proposed,which can show all details except the private key.

Fast algorithms for multi-exponentiation in public key cryptography;

Based on the requirement analysis of public key cryptographic algorithm acceleration,a scalable architecture of public key cryptography coprocessor is presented in this paper.

By using Shor, Boneh and Lipton s quantum algorithms, quantum computers can solve big integer factorization problems, discrete logarithm problems and discrete logarithm problems on elliptic curves, but public key cryptography systems based on these problems will become insecure in the age of quantum computers.

Requiring no heavy infrastructure and complex bootstrapping,certificate chaining becomes a potential candidate for self-organized public key management for mobile ad hoc networks.

The paper,combined with public-key certificate technology, designs a new data encryption scheme based on Hyperelliptic curve.
