  • Security apparatus, method thereof, and program
    Patent number: 10574438
    Abstract: In sharing processing, a security apparatus applies secret sharing to processing information m to obtain a plurality of pieces of fragment information (where n=1, . . . , N), obtains verification information which is an image of the obtained fragment information through mapping, stores the verification information and outputs the fragment information. Each piece of the fragment information is stored in a storage apparatus. In restoration processing, the security apparatus accepts input of fragment information (where k=1, . . . , K) required for restoration, compares fourth verification information which is an image of the inputted fragment information through mapping with stored verification information, and restores the processing information m from the fragment information (where k=1, . . . , K) corresponding to the fourth verification information which matches the verification information.
