RISC-V架构的轻量化内存保护单元
Lightweight memory protection unit based on RISC-V architecture
摘要
Abstract
The rapid development of contemporary information technology not only brings convenience to people,but also creates many security risks.With the rapid development of the Internet and the Internet of Things,the number of globally connected devices is growing rapidly,and"Internet of Things"has become an important direction for the future development of global networks.However,the prosperity of edge IoT proxy devices has also given rise to diverse security issues.However,traditional security protection mecha-nisms have become inefficient on existing edge IoT proxy devices.However,the trusted execution environment is too large and relies on remote authorization and other issues.At present,there are common security risks in applications such as being cracked,data being sto-len and tampered with,posing a great threat to financial data security,personal privacy data protection,and business data integrity.This article proposes a lightweight memory protection unit based on the RISC-V architecture,implementing a hardware secure boot mecha-nism based on hardware trusted roots.By extending the RISC-V instruction set and using newly added instructions to create a memory secure space,the general memory is converted into a secure encrypted space,achieving a trusted embedded system.关键词
