【摘要】 Internet的应用已经深入到生活的方方面面。接入Internet的主体也开始发生变化，除了计算机之外，大量的电器设备也开始尝试着接入Internet。嵌入式Internet(EI，Embedded Internet)技术就是为设备接入Internet而提出来的，其主要目的就是解决设备上网问题。 嵌入式Internet中的关键问题是其实现成本问题和安全问题。8bit处理器在各种电器设备中广泛使用、价格低廉，如果能够在它上面实现嵌入式Internet技术，不仅会大力促进EI的应用发展，而且将会带来巨大的经济效益。本文以普通8bit处理器为出发点，详细论述如何实现EI技术及其相关的安全问题。归纳起来，本文主要进行了以下研究工作。 (1) 在8位普通处理器上实现了嵌入式Internet技术。提出了TCP／IP协议子集划分和协议简化的思想。并且根据8位普通处理器的特点及协议子集划分和简化思想，设计了一套嵌入式Internet的专用接入协议EIAP(Embedded InternetAccess Protocol)。 (2) 系统分析了嵌入式Internet所面临的安全问题，提出了一套适合在8位处理器上实现的嵌入式Internet的安全控制协议EIACP(Embedded Internet AccessControl Protocol)。EIACP协议主要包括会话协议、密钥恢复协议和密钥生成协议。 (3) 根据EIACP协议的具体要求，对其中的密码算法进行了分析，给出了适合在8位普通处理器上实现的杂凑函数和分组密码算法的参考设计。 本文的研究成果已经应用于产品开发中。附录A中列出了基于本文研究成果的几种EI产品。更多还原

【Abstract】 The application of Internet has come into everywhere for people’s daily life. With the rapid development of Internet, besides computer, a great number of electric instruments begin to access Internet, which leads to the development of Embedded Internet technology (El)The key points about El are cost efficient and security ability. 8bit processor, for its low cost, is widely used by different electric instruments. More attention has paid to the realization of El technology on 8bit processor, because it will bring immense economy benefits, but as our knowledge, little research work has been reported so far. In this paper, the realizing El technology and the solution of security ability based on Sbit processor has been studied in detail. The main contributions of the paper are as follow:(1) Implement El in normal Sbit CPU. Developed the idea of subset partition and predigestion for TCP/DP. By this idea, a set of special access protocols, called EIAP (embedded internet access protocol) has been presented.(2) Base on the security analysis, special for Sbit processor used in El, a set of security control protocols, named EIACP, which includes session protocol-, key-create protocol and key-resume protocol has been developed.(3) Presented the design reference of hash algorithm and block cipher suitable for Sbit processor based on die EIACP protocol.The contributions maintained above have been successfully used in some El application products.
