With wide and increasing range applications of mobile agent technology, the security problem has gottenmore and more focus. This paper discusses the security problems that the mobile agent system faces with at presentand the existing protesting schemes for it. Then a solving method based on javacard is proposed to protect mobile a-gents. And a feasible solving method is also provided to solve the security problems of javacard itself.

Smart card is currently a popular embedded device,but it has some drawbacks. On the other hand, Java's reliability,cross platform support,and many other advantages make it fit into embedded systems. The paper discusses every aspect of javacard,the combination of smart card and Java technology,form which,we can conclude Java has great applied potential in embedded devices.

OMA-开放移动联盟(Open Mobile Alliance),是一个由电信业的世界上400多个成员组成的独立组织。在开发全球DRM(Digital Rights Management)-数字权限管理标准的工作中,OMA起着关键作用。OMA DRM是目前DRM领域热点的研究方向之一。OMA DRM是由业界专家共同制定的开放性标准。并被整个联盟共同认可和支持,相对私有方案有很大的优势,也是目前DRM领域发展的重要方向之一。 javacard是智能卡上面实现的Java系统。最早由SUN提出,现在被各大智能卡厂商所支持。也是一种开放的标准。目前最重要的javacard产品就是各大智能卡厂商的SIM卡产品。Java与智能卡的结合不但继承的智能卡安全的特点,又结合了Java语言在开发上的优势。是目前在智能卡开发领域最具竞争力的开发方案。并且由于javacard规范的开放性,在其上实现的方案也将不限定于特定的智能卡厂商。 本文将以上两方面结合起来,提出在javacard上实现OMA DRM服务器的解决方案,即实现一个嵌入式移动服务器。在本文中介绍了在javacard这一嵌入式环境下支持OMA DRM服务的研究工作。其中包括了对OMA DRM 2.0规范的理解和裁剪并提出了支持HTTP服务的方式以及一个轻量级的XML解析器的方法以适应javacard的性能特点。将几个部分结合最终在javacard上实现了一个OMADRM授权服务器。

The Message Queuing Telemetry Transport (MQTT) protocol is one of the most extended protocols on the Internet of Things (IoT). However, this protocol does not implement a strong security scheme by default, which does not allow a secure authentication mechanism between participants in the communication. Furthermore, we cannot trust the confidentiality and integrity of data. Lightweight IoT devices send more and more sensible data in areas of Smart Building, Smart City, Smart House, Smart Car, Connected Car, Health Care, Smart Retail, Industrial IoT (IIoT), etc. This makes the security challenges in the protocols used in the IoT particularly important. The standard of MQTT protocol strongly recommends implement it over Transport Layer Security (TLS) instead of plain TCP. Nonetheless, this option is not possible in most lightweight devices that make up the IoT ecosystem. Quite often, the constrained resources of IoT devices prevent the use of secure asymmetric cryptography algorithms implemented by themselves. In this article, we propose making a security schema in MQTT protocol using Cryptographic Smart Cards, for both challenges, the authentication schema and the trusted data confidentiality and data integrity. We carry out this security schema without modifying the standard protocol messages. And finally, we present a time results experiment using an example implementation model with javacard library.
