ReCon Implementation on RISC-V Processor
Implemented load pair-tracking mechanism in BOOM core to reduce performance impact of security protections against speculative side-channel attacks.
About This Project
Implemented load pair-tracking mechanism in BOOM core (speculative out-of-order RISC-V processor) to reduce performance impact of security protections against speculative side-channel attacks. Developed hardware modifications using Chisel HDL to allow certain loads to bypass security protections, reducing performance hit while maintaining security against transient execution attacks. Validated performance improvements through comprehensive testing and analysis of speculative execution behavior.
