Abstract
To provide a semiconductor device and a control method for a semiconductor device that realizes high-speed processing. The semiconductor device includes a storage unit, an encryption processing unit, and a hash processing unit. The data stored in the storage unit is transferred to the encryption processing unit for each pre-calculation data of the first calculation unit, the encryption processing unit applies the calculation processing to generate post-calculation data. The generated first calculation unit of the post-calculation data is transferred to the hash processing unit, the hash processing unit applies the hash calculation process to the post-calculation data of the second calculation unit. The post-calculation data is transferred to the storage unit, and the calculation processing and the hash calculation processing are performed in parallel.
