【摘要】：隨著計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)的飛速發(fā)展和廣泛應(yīng)用,失泄密事件層出不窮,網(wǎng)絡(luò)安全問(wèn)題也變得越來(lái)越受人們重視。密碼協(xié)議是解決網(wǎng)絡(luò)信息安全問(wèn)題的最有效手段之一。開(kāi)展對(duì)認(rèn)證密鑰協(xié)商協(xié)議的研究不僅在密碼學(xué)和信息安全領(lǐng)域具有重要的理論意義,而且在計(jì)算機(jī)通信網(wǎng)絡(luò)應(yīng)用和各種新興電子業(yè)務(wù)中具有重要的應(yīng)用價(jià)值。本文以孫氏協(xié)議為例,結(jié)合最新的理論研究進(jìn)展,針對(duì)協(xié)議中存在的安全缺陷做出了相應(yīng)的改進(jìn)。最后,本文還設(shè)計(jì)了新的高效身份基認(rèn)證密鑰協(xié)商協(xié)議,并使用啟發(fā)式分析方法對(duì)其進(jìn)行了安全性分析。具體研究成果如下:1、對(duì)雙方身份基認(rèn)證密鑰協(xié)商協(xié)議的發(fā)展及研究現(xiàn)狀進(jìn)行了綜述,描述了密鑰協(xié)商協(xié)議的概念、安全特性、設(shè)計(jì)原則等。對(duì)著名的認(rèn)證密鑰協(xié)商協(xié)議進(jìn)行了描述和分析。2、對(duì)國(guó)內(nèi)孫氏SSZP協(xié)議進(jìn)行了分析與改進(jìn)。本文對(duì)其安全性進(jìn)行了詳細(xì)分析,表明該協(xié)議不滿足抗密鑰泄露偽裝攻擊的安全屬性。論文詳細(xì)描述了針對(duì)該協(xié)議的密鑰泄露偽裝攻擊過(guò)程。最后,針對(duì)SSZP協(xié)議的上述安全缺陷,提出了改進(jìn)協(xié)議(SSZP+協(xié)議)。對(duì)新協(xié)議分析表明針對(duì)孫氏SSZP協(xié)議的密鑰泄露偽裝攻擊對(duì)于SSZP+協(xié)議將變得不再有效。3、在前兩部分工作的基礎(chǔ)上,論文提出了一個(gè)新的安全、高效的身份基雙方認(rèn)證密鑰協(xié)商協(xié)議——IDAK協(xié)議。給出了實(shí)現(xiàn)改協(xié)議的相關(guān)程序,并進(jìn)行了嚴(yán)格的測(cè)試,測(cè)試結(jié)果相對(duì)前面分析的幾種協(xié)議有了較大的改進(jìn)。分析表明,這一協(xié)議不僅保持了同Smart協(xié)議完全相同的計(jì)算效率,而且還滿足了應(yīng)有安全屬性。通過(guò)與文中所涉及的其它協(xié)議在計(jì)算效率和安全屬性方面進(jìn)行詳細(xì)比較之后,新提出的協(xié)議在計(jì)算效率和安全性方面達(dá)到了一個(gè)較好的平衡,具有很強(qiáng)的實(shí)用性。
[Abstract]:With the rapid development and wide application of computer network technology, leakage incidents emerge in endlessly, and network security issues have become more and more important. Cryptographic protocol is one of the most effective methods to solve the problem of network information security. The research of authentication key agreement protocol is of great theoretical significance not only in the field of cryptography and information security, but also in the applications of computer communication networks and various new electronic services. Taking Sun's protocol as an example, combined with the latest theoretical research progress, this paper makes corresponding improvements to the security defects in the protocol. Finally, a new efficient authentication key agreement protocol is designed, and its security is analyzed by heuristic analysis method. The specific research results are as follows: 1. This paper summarizes the development and research status of the authentication key agreement protocol between the two sides, and describes the concept, security characteristics and design principles of the key agreement protocol. The famous authentication key agreement protocol is described and analyzed, and the Sun's SSZP protocol is analyzed and improved. The security of the protocol is analyzed in detail, which shows that the protocol does not satisfy the security properties of key disclosure camouflage attack. This paper describes the process of key leak camouflage attack against the protocol in detail. Finally, an improved SSZP protocol (SSZP protocol) is proposed for the above security defects of SSZP protocol. The analysis of the new protocol shows that the key leak camouflage attack against Sun's SSZP protocol will no longer be effective for SSZP protocol. Based on the first two parts of the work, this paper proposes a new security. Efficient identity Base Authentication key Agreement Protocol-IDAK Protocol. The related procedures for implementing the protocol are given, and a strict test is carried out. The test results are better than those of the previous protocols. The analysis shows that this protocol not only keeps the same computing efficiency as Smart protocol, but also satisfies the due security attribute. Compared with other protocols in this paper, the proposed protocol achieves a good balance in computing efficiency and security, and has strong practicability.
