摘要： In a receiving clock reproducing method, an estimated value of delay time fluctuation of a received signal is estimated at intervals defined by transmitting clock included in the received signal. To estimate the estimated value, an oscillator counter counts pulses of a reference clock supplied from an independent oscillator while a reading counter counts pulses of the receiving clock. The estimated value is used to control a voltage controlled oscillator for producing the receiving clock.

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： Each participant apparatus (103) encrypts a plaintext by using a secret key of secret key cryptography, encrypts the encryption key by a public key, and sends the plaintext and public key to a substitution/decryption apparatus (112). With this processing, the limitation on the length of a ciphertext to be processed can be eliminated. In this invention, a verifiable proof text using a public key by each substitution/decryption apparatus is verified by a verification apparatus (109) by using the public key. If one of a plurality of organizations to decrypt and shuffle ciphertexts has not correctly executed the operation, a third party can specify it and prove that the specified organization is unauthorized.
