Some people may think so much good ah, I as far as possible in the META that much key word divides in oneself, such search engine can give him more chances probably, actually such key word does not have real significance at all to your website, overmuch false key word still can be punished certainly likely.

有些人可能会想这样多好啊，我把尽可能多的关键字都分在自己的META中，这样搜索引擎或许会给自己更多的机会，其实这样的关键字对你的网站来说根本没有实际的意义，过多的虚假的关键字有可能还会受到一定的处罚。

Hybrid schemes in a KEM-DEM structure is regarded as the most natural approach to public key encryption with IND-CCA security and practical efficiency. Traditional KEM is realized by public key scheme, which only provides confidentiality security for session key used by DEM. In 2005, combining the idea of signcryption with the KEM-DEM model hybrid encryption, Alexander proposed a signcryption KEM-DEM model hybrid signcryption primitive.

KEM-DEM结构的混合密码体制是获得IND-CCA安全最实际有效的方法，传统的KEM由公钥加密方案实现，仅提供DEM使用的会话密钥的保密性安全。2005年Alexander等人将签密的概念与KEM-DEM结构的混合密码体制相结合，提出了Signcryption KEM-DEM结构的混合签密。

This invention provides a method for transferring third party landing based on IP network including: a door network station carries a ciphered KEY generated randomly by a service server to send a link request to a third party network station so as to avoid transmission of user ciphered codes and ensure absolute security of user codes, besides, since the third party network station calls back the Web server by copying the ciphered KEY to verify the cryptographic key so as to secure the absolute safety of shaking hands, since the door network station does not transfer user ciphered codes with the third party network station, which is not necessary to synchronize with the door station about codes, thus the requirement of complicated maintenance to synchronization on ciphered codes to the third party is reduced.

本发明提供了一种基于IP网络转接第三方登陆的方法，其关键是，由门户网站携带业务服务器随机生成的加密KEY向第三方网站发送链接请求，避免了用户密码的传输，因而保证了用户密码的绝对安全性。再有，由于第三方网站通过复制加密KEY回调Web服务器，由Web服务器进行密钥验证，因而又保证了握手的绝对安全性。应用本发明，由于门户网站与第三方网站之间不传递用户密码，使得第三方网站无需与门户网站进行密码同步等机制的处理，在大大提高安全性的同时，降低了对第三方网站对于密码同步机制等复杂维护的要求。

A code rule of correspondence mapping from secret key to magic cube transformation is proposed,Which can realize that the secret key is not limited by both type and size,and the key space is huge.

提出了一种新的密钥与魔方变化的编码对应法则，使该加密算法的加密密钥不受类型、大小的限制，具有密钥空间大的特点。

The academic research of this center includes the nation-level key subjects: nonnasality clinic medicine, surgery and inner medicine; Sichuan province-level key subjects such as ophthalmology, psychiatry, and pathological physiology;"211 project" key subjects such as pathology and pathological physiology, surgery, and medical jurisprudence.

该中心的学术科研包括国家级重点学科：口腔临床医学、外科学、内科学；四川省重点学科：眼科学、精神病学、病理生理学等方面；"211工程"重点建设学科：病理学和病理生理学、外科学、法医学等。

The security of PKI system itself is especially emphasized during the system design and implementation process, which is in accordance with the pervasive characteristic of PKI. Second, the concept of a Trusted Key Management Center is introduced for the first time. This technology greatly strengthens key management practices and allows for smooth transition from PKI to Key Management Infrastructure. Third, certificate status mechanisms are investigated in depth, and a certificate revocation performance simulation system is devised. All these work will provide guides to practice and employment of PKI applications. Based on time constraints, a new taxonomy for authenticated dictionaries is proposed. Fourth, formal analysis ofOCSP protocol is carried out; then an efficient and scalable OCSP system is developed. Fifth, the special requirements caused by the working environments of Wireless PKI are analyzed. Based on communicative hashing and dynamic Merkle hash tree, an efficient certificate status validation method suitable for WPKI is presented. Sixth, one important kind of fair exchange protocols is studied, and a new CEMBS based on RSA cryptosystem is proposed. Afterwards, a novel fair exchange protocol totally based on RSA signature scheme is devised.
