摘要： In sharing processing, a security apparatus 12 applies secret sharing to processing information m to obtain a plurality of pieces of fragment information s n (where n = 1, ..., N), obtains verification information h n which is an image H(s n ) of the obtained fragment information s n through mapping H, stores the verification information h n and outputs the fragment information s n . Each piece of the fragment information s n is stored in a storage apparatus 13-n. In restoration processing, the security apparatus 12 accepts input of fragment information s f(k) (where k = 1, ..., K) required for restoration, compares fourth verification information which is an image H(s f(k) ) of the inputted fragment information s f(k) through mapping H with stored verification information h f(k) , and restores the processing information m from the fragment information s f(k) (where k = 1, ..., K) corresponding to the fourth verification information H(s f(k) ) which matches the verification information h f(k) .

摘要翻译：在共享处理中，安全装置12对处理信息m应用秘密共享以获得多条片段信息sn（其中n = 1，...，N），获得作为图像H（sn）的验证信息hn，通过映射H获得的片段信息sn存储验证信息hn并输出片段信息sn。每条片段信息s n被存储在存储装置13-n中。在恢复处理中，安全装置12接受对恢复所需的片段信息sf（k）（其中k = 1，...，K）的输入，比较作为恢复的图像H（sf（k））的第四验证信息通过映射H和存储的验证信息hf（k）来输入片段信息sf（k），并且从与第四验证对应的片段信息sf（k）（其中k = 1，...，K）恢复处理信息m 与验证信息hf（k）匹配的信息H（sf（k））。
