摘要： A proof of retrievability (POR) mechanism is applicable to a file for providing assurances of file possession to a requesting client by transmitting only a portion of the entire file. The client compares or examines validation values returned from predetermined validation segments of the file with previously computed validation attributes for assessing the existence of the file. Since the archive server does not have access to the validation function prior to the request, or challenge, from the client, the archive server cannot anticipate the validation values expected from the validation function. Further, since the validation segments from which the validation attributes, and hence the validation values were derived, are also unknown to the server, the server cannot anticipate which portions of the file will be employed for validation.
摘要翻译： 可检索性（POR）机制的证明适用于通过传送整个文件的一部分来向请求客户端提供文件拥有保证的文件。 客户端比较或检查从文件的预定验证段返回的验证值与先前计算的验证属性，以评估文件的存在。 由于存档服务器在请求之前无法访问验证函数，或者从客户端询问，归档服务器无法预期验证函数预期的验证值。 此外，由于从其导出验证属性以及因此导出验证值的验证段对于服务器而言也是未知的，所以服务器不能预期该文件的哪些部分将用于验证。

摘要： Secure authentication protocols, particularly well-suited for use in authenticating mobile communications devices having limited computational resources, are disclosed. In an illustrative embodiment, a network-based communication system includes a client device and at least two servers. First and second shares are generated from a first password associated with the client device, and stored in respective first and second servers. The client device submits additional information associated therewith to at least one of the first and second servers. Each of the first and second shares has the property that it is infeasible to determine solely therefrom correspondence of the additional information with the first password. The first and second servers then utilize the respective first and second shares to collectively determine said correspondence of the additional information with the first password.

摘要： A first processing device, which may be, for example, a wireless authentication token or an RFID tag, transmits information in a wireless network in a manner that emulates standard communications of an access point of the wireless network, although the first processing device is not configured to operate as an actual access point of the wireless network. A second processing device, which may be, for example, a computer or other station of the wireless network, receives the transmitted information and is able to determine therefrom that the information originates from an emulated access point rather than an actual access point. The second processing device responds to this condition by utilizing the transmitted information in a manner distinct from its utilization of similar information received from the actual access point of the wireless network.

摘要： A method and system for generating an authentication code that depends at least in part on a dynamic value that changes over time, an event state associated with the occurrence of an event, and a secret associated with an authentication device. By generating the authentication code responsive to an event state, an identity authentication code can be used to verify identity and to communicate event state information, and to do so in a secure manner.

摘要： Techniques for providing authentication functionality in a gaming system are disclosed. In one aspect, a gaming system is configured such that, at a given point during a current session of a game in progress that involves at least one user previously granted access by the system to participate in the current session, information available from an authentication token associated with the user is obtained prior to allowing the user to take a particular action in the game. A determination is made as to whether or not the user will be allowed to take the particular action in the game, based on the obtained information. The obtained information may comprise, for example, at least a portion of a one-time password generated by a hardware or software authentication token.

摘要： In one aspect, a first processing device, which may be an authentication token, establishes a shared key through a pairing protocol carried out between the first processing device and a second processing device. The pairing protocol also involves communication between the second processing device and an authentication server. As part of the pairing protocol, the first processing device sends identifying information to the second processing device, and the second processing device utilizes the identifying information to obtain the shared key from the authentication server. The first processing device encrypts authentication information utilizing the shared key, and transmits the encrypted authentication information from the first processing device to the second processing device. The second processing device utilizes the shared key to decrypt the encrypted authentication information.

摘要： In a system comprising a transient storage device (TSD) or other type of peripheral configured for communication with a host device, a first one-time password or other type of code is generated in the peripheral and transmitted to the host device. The first code is presented by the host device to an authentication server for authentication. The host device receives a second one-time password or other type of code from the authentication server and transmits it to the peripheral for authentication.

摘要： In general, in one aspect, the invention relates to a method for accessing encrypted data by a client. The method includes receiving from the client by a server client information derived from a first secret wherein the client information is derived such that the server can not feasibly determine the first secret. The method also includes providing to the client by the server intermediate data, which is derived responsive to the received client information, a server secret, and possibly other information. The intermediate data is derived such that the client cannot feasibly determine the server secret. The method also includes authenticating the client by a device that stores encrypted secrets and is configured not to provide the encrypted secrets without authentication. After the authenticating step, the method also includes providing the encrypted secrets to the client. The encrypted secrets 5 are capable of being decrypted using a third secret that is derived from the intermediate data.

摘要： Methods and apparatus for converting a value A representing in a first basis an element of a finite field GF(q.sup.m) to a value B representing the element in a second basis, where q is a prime number or power of a prime number and m is an integer greater than or equal to 2, and where the value B includes a vector of m coefficients from a finite field GF(q). An exemplary apparatus, particularly well-suited for exporting the value A in an internal basis representation to the value B in an external basis representation, includes an externally shifted sequence generator for generating from the value A a sequence of intermediate values representing in the first basis elements of the finite field GF(q.sup.m) whose representations in the second basis are related to the value B by a predetermined external shift operation. An extractor coupled to the externally shifted sequence generator receives and processes the sequence of intermediate values to generate each coefficient of the value B.
