【摘要】：當(dāng)前,移動智能終端得到廣泛普及,功能也日益強(qiáng)大。被應(yīng)用于支付、辦公等各個領(lǐng)域。困擾傳統(tǒng)PC的數(shù)據(jù)安全問題也轉(zhuǎn)移到移動智能終端上來。加密成為保護(hù)移動智能終端數(shù)據(jù)安全的重要方法。然而,現(xiàn)有智能手機(jī)軟件加密產(chǎn)品存在加密速度慢、密鑰安全性差、安裝過程復(fù)雜等問題,不能滿足業(yè)務(wù)處理系統(tǒng)的需求。應(yīng)用硬件加密設(shè)備開發(fā)高級加密應(yīng)用,雖然保密性高,但是也存在一系列障礙包括語言障礙、使用復(fù)雜、學(xué)習(xí)困難和開發(fā)效率低等。研制智能IC卡應(yīng)用加密工具包輔助開發(fā)者編程,是解決上述問題的方案之一。本文設(shè)計(jì)與實(shí)現(xiàn)的智能IC卡應(yīng)用加密工具包,適用于開發(fā)需要實(shí)現(xiàn)加密存儲和身份認(rèn)證功能的Android手機(jī)應(yīng)用程序,支持國家密碼管理局頒布的國密算法;同時支持PKI和CPK兩種認(rèn)證體制;工具包最終以第三方共享庫的形式發(fā)布。經(jīng)過測試,該工具包不僅功能齊全,且運(yùn)算速率比其他同類工具包優(yōu)秀。主要完成以下工作:第一,闡明本文研發(fā)的加密工具包在安全系統(tǒng)中所處層次。簡述JNI技術(shù)實(shí)現(xiàn)原理,詳細(xì)說明Android NDK開發(fā)環(huán)境的搭建方法,并概括Android NDK編程的具體步驟。第二,分析了智能IC卡應(yīng)用加密工具包的需求,設(shè)計(jì)了模塊結(jié)構(gòu),包括數(shù)據(jù)管理、國密對稱算法、國密非對稱算法和國密雜湊算法等模塊。完成了各模塊詳細(xì)設(shè)計(jì)和編碼實(shí)現(xiàn)。第三,設(shè)計(jì)并實(shí)現(xiàn)了Android平臺下的GUI測試程序,完成加密工具包功能測試和性能測試。
[Abstract]:At present, the mobile intelligent terminal is widely popularized, the function is becoming more and more powerful. It is used in payment, office and other fields. The data security problem of traditional PC is also transferred to mobile intelligent terminal. Encryption has become an important method to protect the data security of mobile intelligent terminal. However, the existing smart phone software encryption products have some problems, such as slow encryption speed, poor key security, complex installation process, etc., which can not meet the needs of business processing system. Although the application of hardware encryption devices to develop advanced encryption applications, although high confidentiality, but there are a series of obstacles including language barriers, complex use, learning difficulties and low development efficiency. It is one of the solutions to solve the above problems to develop intelligent IC card application encryption toolkit to help developers program. The intelligent IC card application encryption toolkit designed and implemented in this paper is suitable for the development of Android mobile phone application program which needs to realize encryption storage and identity authentication and supports the national secret algorithm promulgated by the State Cryptography Administration. At the same time, it supports PKI and CPK authentication schemes. Finally, the toolkit is released as a third party shared library. After testing, the toolkit is not only fully functional, but also better than other similar toolkits. The main work is as follows: first, the encryption toolkit developed in this paper in the security system level. The realization principle of JNI technology is briefly described, the method of setting up Android NDK development environment is explained in detail, and the concrete steps of Android NDK programming are summarized. Secondly, the requirement of intelligent IC card application encryption toolkit is analyzed, and the module structure is designed, including data management, country secret symmetry algorithm, country secret asymmetric algorithm and national secret hash algorithm and so on. Each module is designed and coded in detail. Thirdly, the GUI test program based on Android platform is designed and implemented, and the function test and performance test of encryption toolkit are completed.
