摘要： A decryption method and device, an access right authentication method and apparatus for securely transmitting specific information to the decryption device while retaining blindness of data that is assigned to be decrypted. An input unit of the decryption device receives a cipher text C′ generated by providing a blind effect to a cipher text C and second decryption information d2 from a user and transmits them to a decryption unit. The decryption unit takes a modulus n and first decryption information d1 from a modulus storage unit and a first decryption information storage unit, respectively. The decryption unit then calculates the expression R=C′d1d2 mod n and outputs R through an output unit. If a combination of a cipher text C and the second decryption information d2 is correct, a correct decryption result is available.

摘要： The present invention allows even small-size verification devices to authenticate rights and qualifications without leaking authentication characteristic information to third parties. A ticket issuance device computes document private information &mgr; from a private function f of an interaction device owned by a user and document m to be transferred to the interaction device when generating interaction, and issues ticket t generated from authentication characteristic information x and the document private information &mgr; to the user. The interaction device, when document m is input, generates document private information &mgr; using a private function f specific to the interaction device, and performs interaction based on the document private information. The interaction comprises output of commitment r, input of challenge &khgr;, output of response &sgr;, and message M output. The user converts interaction (r, &khgr;, M, &sgr;) into interaction (r, &khgr;, M, s) using ticket t to perform Guillou-Quisquater authentication.
摘要翻译：本发明允许甚至小尺寸的验证设备认证权限和资格，而不会向第三方泄漏认证特征信息。票据发行装置从生成交互的用户所拥有的交互装置的私有函数f和文档m计算文档私有信息mu，并且从认证特征信息x和文档私有密钥生成票证t 信息mu给用户。当输入文档m时，交互设备使用特定于交互设备的专用功能f生成文档私有信息mu，并且基于文档私有信息执行交互。交互包括承诺的输出，挑战的输入，响应的输出和消息M的输出。用户使用票证t将交互（r，chi，M，sigma）转换为交互（r，chi，M，s），以执行Guillou-Quisquater身份验证。

摘要： A burden caused by handling a large number of unique identifying information pieces such as authentication keys is to be lightened from both the user side and the protector side such as application creators. A proof data verification device sends authentication data to a proof data generation device. The proof data generation device generates proof data from both received authentication data and user unique identifying information held therein and sends it back to the proof data verification device. The proof data verification device holds an access ticket and authentication data, and verification means in the verification device performs a signature verifying calculation by use of the proof data, authentication data, and the access ticket. If the verification is successful, the execution of program is allowed.

摘要： A burden caused by handling a large number of unique identifying information pieces such as authentication keys is to be lightened from both the user side and the protector side such as application creators. A proof data verification device sends authentication data to a proof data generation device. Signature data generation means and presignature data generation means in the proof data generation device cooperate with each other to generate proof data (a signature based on a discrete logarithm problem) from the received authentication data as well as held user unique identifying information and an access ticket, and send the proof data back to the proof data verification device. Verification means in the proof data verification device verify the signature, and if the verification is successful, the execution of program is allowed.

摘要： A system includes an image formation apparatus, an image retrieval server, and image storage servers, and a network for connecting them. The image formation apparatus forms an image based on image data, records the image data in a predetermined storing location on the image storage servers, converts the image data under a predetermined rule to generate an image identification information as a key in order to read the image data from the storing location, and outputs the image identification information. Upon reception of an image data retrieval request together with an image identification information, the image retrieval server determines that the image data whose result of conversion under the predetermined rule is equal to the image identification information, among at least one image data stored in a predetermined storing location on the image storage servers, is the image data to be retrieved, and outputs its information.

摘要： An electronic ticket system for virtually preventing forgery, copying and other unauthorized uses of electronic tickets; for proving to a third party the contents of an electronic ticket contested between a user and an issuing party; and for protecting users' anonymity upon ticket use. The system comprises a ticket creating and issuing device, a ticket proving device, and a ticket verification device. A ticket creating unit in the ticket creating and issuing device creates specifications of a ticket representing a predetermined service or product in response to a ticket creating request. A ticket issuing unit of the ticket creating and issuing device, in reply to a ticket issuing request, issues the corresponding ticket using as input a ticket identifier, a proving identifier, a ticket specification identifier, and ticket added information. The ticket proving device gets a ticket issued by the ticket issuing unit and communicates with the ticket verification device to prove the possession of the ticket. The ticket verification device has a ticket verifying procedure and, on getting the ticket identifier created by the ticket creating unit, communicates with the ticket proving device to verify the ticket.
