    摘要: A microprocessor includes a decryption unit that decrypts information to be utilized by a processor core to obtain plaintext information when the acquired information is encrypted; and a plaintext information storing unit that stores the plaintext information. The microprocessor also includes a protected attribute adding unit that adds a protected attribute indicating one of protection and non-protection to the plaintext information based on whether the decryption has been performed; an access request acquiring unit that acquires an access request to the plaintext information; a request type identifying unit that identifies a type of request of the access request; and an access controlling unit that controls an access to the plaintext information based on the type of request and the protected attribute.

    摘要: According to one embodiment, an encryption device includes a storage unit, an input unit, first to fourth partial encryption units, a generation unit, and an output unit. The first partial encryption unit calculates first intermediate data from input plain data to store in the storage unit. The generation unit generates a round key, which is used in calculations for the first intermediate data and N-th intermediate data, from the secret key. The second partial encryption unit calculates (i+1)th intermediate data from i-th intermediate data (i is smaller than N) and the round key to store in the storage unit. The third partial encryption unit performs an arithmetic operation including predetermined conversion for mixing the N-th intermediate data, and calculates (N+1)th intermediate data to store in the storage unit. The fourth partial encryption unit obtains encrypted data by performing an arithmetic operation including inverse conversion of the conversion on the (N+1)th intermediate data.
