【摘要】 目前对加密技术的研究大多局限于软件领域和贵重电子产品,缺点分别是不可靠和成本高。基于嵌入式硬件对电子产品进行加密,可以通过附加外围电路简单而可靠的硬件来实现,同时弥补了这两点不足;这种方案也考虑到尽量降低体积和功耗,尤其适用于便携式电子产品的加密保护,有较好的市场应用前景。更多还原

【Abstract】 Most of the research of security technique is in the fields of software and expensive electronic products. The defect of the former is low credibility, while the latter one has the defection of high cost. Security technique, which based on embedded hardware, however, has none of the defection above. At the same time, this technique has the advantage of small volume and low power consumption, this advantage allows of applying it to the protection of products in portable electronic equipment with effective performance.更多还原
