摘要:

针对微控制器无法防御未知漏洞和未知后门带来的安全威胁,文章以内生安全理论为基础,设计了一种基于动态异构冗余的微控制器架构。为解决动态异构冗余架构裁决导致的性能短板问题并满足微控制器应用低时延需求,文章提出一种增强系统实时性的裁决输出方法,在确保系统安全性的前提下,降低系统响应时延。此外,设计了内生安全微控制器原型系统,测试了系统安全性及响应时延指标。测试结果表明,文章所提内生安全微控制器系统在识别系统攻击上具有更高的精度,相较于传统先裁决后输出的方式最多缩短了13.78%的响应时间。

Abstract:

In response to the problem that microcontrollers were currently unable to prevent the security threats brought by unknown vulnerabilities and unknown backdoors, the paper first proposed a microcontroller architecture based on dynamic heterogeneous redundancy, grounded in the theory of intrinsic security. Secondly, to overcome the performance bottlenecks caused by the arbitration of dynamic heterogeneous redundancy architecture and to meet the low latency requirements of microcontroller applications, an arbitration output method was proposed to enhance the system’s real-time capabilities, reducing system response latency without compromising system security. In addition, a prototype system of the intrinsically secure microcontroller was designed and implemented, and the system’s security and response latency metrics were tested. The test results indicate that the realized intrinsically secure microcontroller system has higher precision in identifying system attacks, and can reduce the response time by up to 13.78% compared to the traditional method of arbitration before output.

Key words: microcontroller, endogenous security, dynamic heterogeneous redundancy, arbitration and scheduling
