Pre-silicon evaluation and security enhancement for RISC-V AES extensions
针对密码算法加速的指令集架构扩展可能为处理器引入侧信道泄露的风险,提出了一种硅前阶段侧信道安全评估方法,能准确定位处理器运行过程中存在侧信道泄露风险的时刻与微架构组件.基于一款32 bit顺序精简指令集计算机(RISC-V)处理器架构,实现了两种代表性的高级加密标准(AES)扩展指令与扩展硬件电路,而后应用所提出的评估方法对其开展侧信道安全评估.基于评估结果提出了扩展端口动态掩码和运算单元功耗随机化的混合防护策略,进行了硅前安全验证,最终实现了高…查看全部>>
The instruction set architecture(ISA)extension for cryptographic algorithm acceleration may introduce the risk of side channel leakage.A side channel security evaluation process in the pre-silicon stage was proposed,which could accurately locate the time and microarchitecture components with side channel leakage risk during the processor operation.Based on a 32 bit in-order reduced instruction set compute(RISC-V)processor architecture,two representative adva…查看全部>>
