摘要： An information processing apparatus includes: a storage unit that stores a tree structure formed by nodes, each of which is stores identification information identifying a document; and a registration unit that registers documents in the storage unit. The registration unit receives a document including identification information identifying the document and a word set and a key, registers the identification information in a leaf node in the tree structure, and calculates a secure index corresponding to identification information registered in each node from a root node to the leaf node in the tree structure based on the word set and the key. In addition, the registration unit generates a value calculated by adding the calculated secure index as a search index for the document and stores a value calculated by adding a search index generated for each of a plurality of received documents as a search index for the plurality of documents in the storage unit.

摘要： In the present invention, scope search can be effectively performed in a database having encrypted registration information. A plurality of values, first identification information to identify the plurality of values, and a key are accepted as input. A value group is generated from the plurality of values. The value group is treated as a word group, and a secure index is generated from the word group, the first identification information, and the key. On the basis of a value to be retrieved and a key, trapdoor information for the value to be retrieved is generated. With respect to the generated secure index, a secure index assessment process is performed using the trapdoor information. When the value to be retrieved is assessed to be contained in the secure index as a result of the assessment process, second identification information to identify the secure index is output.

摘要： A shared information creating device capable of detecting false alteration of shared information with high probability even if a traitor has shares the number of which is above a threshold and creating shared information whose data size is smaller than that of secret information. A recovering device, a recovery result verifying device, and a secret information sharing system, program, and method are also provided. The shared information creating device generates a polynomial F in which secret information s is embedded, outputs a shared secret information, generates a polynomial G in which the output of when a fixed value t is substituted in the polynomial F is embedded as secret information, and creates shared secret information. A recovering device receives k sets of shared secret information to generate a polynomial F′, and receives k sets of shared shared secret information to generate a polynomial G′. When the value embedded as secret information in the polynomial G′ is equal to the output of when the fixed value t is substituted in the polynomial F′, the embedded value is outputted. When they are not equal, information indicating falsification detection is outputted.

摘要： A transmitting apparatus generates and transmits 3t+1 or more number of codewords for a message and multiple faulty encoded message identifying data, wherein the information regarding the message may not be obtained from t or less number of encoded messages and the message can be decoded from 2t+1 or more codewords. The faulty encoded message identifying data are able to detect t or less number of faulty codewords of the message, even if there are t or less number of faulty codewords. A receiving apparatus checks whether there is no fault in each codeword for the message, using the codewords of the message and faulty encoded message identifying data for the codewords of the message received and the corresponding faulty encoded message identifying data and also checks whether the codewords decided to be non-faulty are all of the same message. The receiving apparatus, if the codewords decided to be non-faulty are all of the same message, decodes the message from the codewords decided to be non-faulty, and outputs the so decoded message and if otherwise, outputs a signal indicating failure in message reception.
