【摘要】 本文目的在于深入研究智能卡技术,尤其是安全技术,运用之,并且开发其技术。其意义在于使安全技术更好的运用在智能卡上,提高智能卡的安全性能。本文选择了智能卡加密技术作为研究对象,通过对Java Card加密安全技术研究,提出了一些能运用于实践的构想并在此基础上进行设计。 本文研究了智能卡安全算法理论,包括对称密码算法(DES,AES),非对称密码算法(RSA,ECC),散列函数,数字签名。介绍了Java Card技术,包括Java Card技术规范,Java Card虚拟机技术,Java Card应用编程接口,Java Card安全技术。在对DES,AES,RSA,ECC加密算法分析的基础上,提出了两种混合密钥系统(DES,RSA)和(AES,ECC)。提出的DES和RSA混合密钥系统在Java Card中的实现这一构想,先设计出混合密钥系统,该系统具有保密和鉴别(数字签名)的功能。在DES,RSA混合密钥系统的基础上,根据Java Card开发步骤,用软件开发了Java Card,给出了DES,RSA算法的类模块及Java Card设计流程图,而后运行成功,表明该方案具有实际可行性。提出的AES和ECC混合密钥系统在Java Card中的实现这一构想,先设计出混合密钥系统,该系统具有保密和鉴别(数字签名)的功能。再介绍SOPC技术和智能卡微计算机结构,在基于混合密钥系统和SOPC技术之上进行Java Card芯片系统设计,给出了芯片系统框图并对其每个模块进行了分析,与原有的传统芯片相比其性价比大大的提高了,并采用定制指令加快混合密码系统的软件实现,提高了软件算法的实现速度,从设计的合理性来看,该款芯片能使AES与ECC混合密钥系统在Java Card中的实现具有可行性。 本文主要完成了以下两个方面的创新:1.设计的DES和RSA混合密钥系统在Java Card中实现,这一实现主要用软件来完成;2.设计的AES和ECC混合密钥系统在Java Card中实现,这一实现主要将AES和ECC算法的特点和SOPC技术结合起来,设计出新型的Java Card芯片,该芯片能很好的实现AES和ECC混合密钥系统。更多还原

【Abstract】 The aim of this paper is that studying technology and exploitation of smart card, especially security. The significance is that making the technology of the security running in the smart card better, and making the technology of smart card is better used . The encrypt of smart card is as the object of studying, through the study of the encrypt security of the Java Card , at same time put forward the thinking exercised in the practice and design it.The paper is studying the security arithmetic theory of smart card, including the symmetry cryptogram arithmetic (DES, AES), dissymmetry cryptogram arithmetic (RSA, ECC), hash function, Digital Signature. And introducing the technology of Java Card, including the Java Card technology criterion, Java Card Virtual Machine(JCVM) technology, Java Card application programme interface, Java Card security technology. At the base of the analyzing the cryptogram arithmetic of DES, RSA, AES, ECC, putting up two mixing secret key encryption system (DES, RSA) and (AES, ECC).In the mixing secret key encryption system (DES, RSA) , first designing mixing secret key encryption system, the system has the functions of encrypt and Digital Signature, and according to Java Card development steps, developing the Java card application, and giving the sound code module and system flow chart, latter running successfully. According to the result, the scheme is feasibility. In the mixing secret key encryption system (AES, ECC), first designing mixing secret key encryption system, the system has the functions of encrypt and Digital Signature, and introducing the sopc and the structure of smart card mircomputer. At base of the mixing secret key encryption system and sopc, designing the chip of the Java Card, giving the system frame and analyzing the every module. Comparing the tradition chip, customization instruction quickening the software implement of mixing secret key encryption system, improving the speed of the arithmetic software. The chip makes the feasibility of mixing secret keyencryption system (AES, ECO running in the Java Card.The paper achieves two innovations: 1 .the mixing secret key encryption system (DES, RSA) realized in the Java Card, completed by the software. 2. the mixing secret key encryption system (AES, ECC)realized in the Java Card, it is realized by mixing the the mixing secret key encryption system (AES, ECO and the sopc, designing the new type Java Card chip, the chip is realizing the the mixing secret key encryption system.更多还原
