McEliece PKC and Niederreiter PKC are thought to be secure against quantum adversaries,so they can be worked as candidates for PKC in the era of quantum computer.

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.

This paper presents a system of the network security, which is based on the public key cryptograph, and has a wide application in the automation of military commanding.
