  • Patent number: 8619917
    Abstract: A decoding apparatus and method of a terminal in a wireless communication system are provided. A carrier to interference and noise ratio (CINR) estimator estimates a CINR value of a received signal, and a controller generates a modulation and coding scheme (MCS) level candidate set satisfying the estimated CINR value and a target packet error rate (PER) based on a look-up table. A decoder switch determines if an MCS level of a burst is included in the MCS level candidate set when the burst having no connection identifier (CID) information exists in a corresponding frame, and determines to decode the corresponding burst if the MCS level of the burst is included in the MCS level candidate set and to discard the burst otherwise.

  • Patent number: 7225165
    Abstract: The invention enables a provider and a retailer of digital contents to issue an electronic license to a consumer without wasting its own resources. A retailer sells digital contents to a consumer via the Internet. The retailer requests a license-issuing center to issue an electronic license corresponding to the digital contents and the user of the contents and receives the generated license. The user receives the license from the retailer via the Internet. The terminal used by the user certifies that he/she is a legitimate user using his/her license when he/she uses the digital contents provided from the provider. When the license is verified, the user can use the digital contents.

  • Patent number: 7159113
    Abstract: Distributors can verify a signature without acquisition of a certificate for each signer from the certificate authority. A signature part calculates a hash value of distribution information and sets it to a variable h (step S412). Signer private information is taken out from a first signer private information storage part and set to the variable d (step S413). A signature key information selection part takes out signature key information corresponding to a product identifier pid from a signature key information storage part and sets it to the variable t, n (step S414). A signature part calculates a first signature value to the variable h by use of signer private information d and sets it to the variable r1 (step S415). A distribution information generating part calculates a second signature value to the variable h by use of a signature key information t according to the variable h (step S416). A signature value to the final variable h is calculated by use of the results r1 and r2.

  • Patent number: 7155745
    Abstract: An application of a client includes a proof data generation device, a command generation device, and a command issuing device. A command and proof data are sent to a server from the application of the client, and a command management device of the server receives them. A proof data verification device verifies the access right of a user to the application on the basis of the proof data, and enables a data storage device to be accessed in accordance with the command, if the verification is successful. The data storage device, used instead of a commonly used hard disk drive, includes a phase change type optical memory or a phase separation type optical memory to execute write once recording. Thus, the access to the data storage device is flexibly controlled.

  • Patent number: 6996723
    Abstract: Integrity of data is to be ensured in a simple manner. A data verifier generates a signature generation request from data to be signed and signature request time, and sends the request to a data generator. The data generator extracts the data to be signed from the signature generation request, and its signature generation unit generates a signature for the data. A key generation unit generates a key from a previous key, the signature request time in the signature generation request, and the identifier of the data generator, and an encryptor encrypts the signature. After that, the encrypted signature and the like are returned to the data verifier, which generates a decrypting key with a key generation unit from the previous key, the signature request time, and the identifier of the data generator, then extracts an encrypted signature, and decrypts it with a decryptor. A signature verification unit checks whether or not the result of decrypting is the correct signature.

  • Patent number: 6950808
    Abstract: Booking venders are to be enabled to issue booking certificates without having to consume their own resources. Advance booking is made and sent to a retailer from a consumer terminal via the Internet. The retailer requests a booking certificate issuing center to issue a booking certificate associated with the product or the booking party, and receives the booking certificate issued from the booking certificate issuing center. The consumer terminal receives the booking certificate from the retailer via the Internet, and uses it to have itself verified to be the legitimate booking party by a verifying apparatus associated with a provider. The booking party can receive the supply of the booked product or service if its booking certificate is successfully verified.

  • Patent number: 6651167
    Abstract: A method and a system for authentication whereby authentication characteristic information is not disclosed to a third party when a verifier uses a verification device of a limited scale to authenticate a user's rights or qualifications. A ticket issuing device interacts with the user's interactive device having a secret function f to calculate document secret information &mgr; based on a document m (data) to be transmitted to the interactive device, whereby the user is issued a ticket t generated from authentication characteristic information x and the document secret information &pgr;. Upon receipt of the document m, the interactive device generates the document secret information using its unique secret function f to perform an interaction based on the generated information. The interaction involves output of a commitment r, input of a challenge c, and an output of a response &sgr;.

  • Patent number: 6073234
    Abstract: Both of a user side and a protect side such as a programmer of an application programmer need not handle a large number of inherent information such as authentication keys. An access ticket generation device generates an access ticket from user unique identifying information and access rights authentication feature information. As unique security characteristic information, there is used a secret key of an elliptic curve encryption or an ElGamal encryption. A proof data generation device receives the access ticket, converts authentication data received from a proof data verification device into proof data by use of the access ticket and the user unique identifying information, and returns the resultant proof data to the proof data verification device. The proof data generation device or the proof data verification device decrypts the above-mentioned encryption.

  • Patent number: 5832455
    Abstract: A user operates a user interface to select a rule for executing the process of a work flow, which is stored in a personal data base or a shared data base, and sends the conditional part of the selected rule as the goal to a query portion. Then, the query portion successively executes the process of the work flow through the computation by the SLD contradiction. When the goal fails in the execution by the computation, the failure goal is transferred as a tapple to the tapple space. The tapple is solved by another query portion, and the result of executing the tapple is returned to the tapple space. If a rule for executing the tapple is not found, the task is processed by man or a user and the result of the processing is entered into the system. In answer to this, the system interprets that the task has been proved to be true, and continues the execution of the work flow process.
