During the partitioning process of the RISC-V architecture processor,it is not in a trusted security environment,which causes the problem of the new row content replacing the old row content at will in some partition content,resulting in more overlapping parts of partition results.Therefore,a secure partitioning method for RISC-V architecture processors based on trusted execution environment is proposed.According to the virtual machine ID number in the request instruction,the virtual machine is bound to the virtual root instance to provide a secure environment for the security division in the RISC-V architecture processor.Integrate the secure memory encryption engine between the internal cache and the storage controller to generate single-shot chunks.The multi-user key symmetry algorithm is used to obtain the access ciphertext,and the Monte Carlo method is used to calculate the offset time corresponding to the current partition solution vector.According to the offset time series,the Cache method is used to color the physical pages of the partitioned trusted channel to avoid the problem of replacing old rows with new rows and obtain safe partitioning results.It can be seen from the experimental results that the minimum value of partition hit rate can reach 0.82 using the research method,which can achieve the ideal partition effect.
