  • Patent number: 9031234
    Abstract: 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.

  • Patent number: 8995666
    Abstract: According to one embodiment, in a key scheduling device, a non-linear transformation unit non-linearly transforms at least one of partial keys resulting from dividing an expanded key. A first linear transformation unit includes first and second circuits. The second circuit linearly transforms the partial key by directly using a transformation result from the non-linear transformation unit. A first storage stores the partial key linearly transformed by the first linear transformation unit. A second linear transformation unit linearly transforms, inversely to the first linear transformation unit, each of partial keys other than the partial key linearly transformed by the second circuit out of the partial keys stored in the first storage, and outputs inversely transformed partial keys. A second storage stores one of inputs to the second circuit. An outputting unit connects the respective inversely transformed partial keys and the input stored in the second storage to be output as a second key.

  • Patent number: 8918654
    Abstract: A first storage unit stores a plurality of security functions each defining a first protection attribute requiring a storage of a value of an argument for input/output of data. A second storage unit stores a program list describing a second protection attribute of a variable indicating a storage area of the data and an executing procedure of a predetermined process. An identifying unit identifies a third protection attribute of an actual argument for input/output of a security function based on the second protection attribute. When a judging unit judges not all of third protection attributes match with first protection attributes, an output unit outputs error information indicating a mismatch of the protection attributes.
