文中阐述了密码学前沿的四个主要方向及一项重大密码学活动:量子密码学,混沌密码技术,椭圆曲线密码(ECC)理论,Ntru公钥密码体制及新欧洲密码计划。ECC与Ntru公钥密码体制是目前最先进、高效的公钥密码算法。作者认为它们与20世纪的RSA一样,将成为未来公钥的领袖。混沌方法是流密码充满活力的一项技术,将对流密码技术产生重大的影响。量子密码是密码理论的又一次革命,它把密码体制的安全性建立在物理定律上,而不是通常的数学难题和置乱技术上,它把一次一密技术从理论变为现实。作者认为,这是密码学又一个里程碑。有人认为量子密码走向实用的一天就是传统密码学寿终正寝之时,量子密码是未来唯一完全安全的密码算法。
The paper describes four main directions of cryptology and one major cryptographic activity: quantum cryptography, chaotic cryptography, elliptic curve cryptography (ECC) theory, Ntru public-key cryptosystem, and new European cryptography. ECC and Ntru public key cryptosystem is the most advanced and efficient public key cryptosystem. The authors think they, like the 20th century RSA, will become the leaders of the future public key. Chaos method is a dynamic flow cipher technology, will have a significant impact on the stream cipher technology. Quantum cryptography is another revolution in cryptographic theory. It sets the security of the cryptosystem in the laws of physics, rather than the usual math problems and disorganization techniques. It transforms a cryptographic technique from theory into reality. The author believes that this is another milestone in cryptography. Some people think that quantum cryptography is a practical day when traditional cryptography came to an end. Quantum cryptography is the only completely secure cryptographic algorithm in the future.
