摘要： Controlling access includes providing a barrier to access that includes a controller that selectively allows access, at least one administration entit y generating credentials/proofs, wherein no valid proofs are determinable give n only the credentials and values for expired proofs, the controller receiving the credentials/proofs (152, 154), the controller determining if access is presently authorized, and, if access is presently authorized, the controller allowing access (168). The credentials/proofs may be in one part or may be i n separate parts (152, 154). There may be a first administration entity that generates the credentials (154) and other administration entities that generate proofs (152). The first administration entity may also generate proofs or the first administration entity may not generate proofs. The credentials may correspond to a digital certificate that includes a final value (166) that is a result of applying a one way function (164) to a first one of the proofs (152).

摘要： The method can include reviewing real time credentials, wherein the real time credentials include a first part that is fixed and a second part that is modified on a periodic basis, wherein the second part provides a proof that the real time credentials are current; verifying validity of the real time credentials by performing an operation on the first part and comparing the result to the second part; and allowing physical access only if the real time credentials are verified as valid.

摘要： A system and method are disclosed for controlling physical access through a digital certificate validation process that works with standard certificate formats and that enables a certifying authority (CA) to prove the validity status of each certificate C at any time interval (e.g., every day, hour, or minute) starting with C's issue date, D1. C's time granularity may be specified within the certificate itself, unless it is the same for all certificates. For example, all certificates may have a one-day granularity with each certificate expires 365 days after issuance. Given certain initial inputs provided by CA, a one-way hash function is utilized to compute values of a specified byte size that are included on the digital certificate and to compute other values that are kept secret and used in the validation process .

摘要： At least one administration entity controls access to an electronic device by the at least one administration entity generating credentials and a plurality of corresponding proofs for the electronic device, wherein no valid proofs are determinable given only the credentials and values for expired proofs, the electronic device receiving the credentials, if access is authorized at a particular time, the electronic device receiving a proof corresponding to the particular time, and the electronic device confirming the proof using the credentials. The at least one administration entity may generate proofs after generating the credentials. A single administration entity may generate the credentials and generate the proofs. There may be a first administration entity that generates the credentials and other administration entities that generate proofs. The first administration entity may also generate proofs or may not. The credentials may be a digital certificate that includes a final value that is a result of applying a one way function to a first one of the proofs. Each of the proofs may be a result of applying a one way function to a future one of the proofs. The digital certificate may include an identifier for the electronic device.

摘要： Providing path validation information for a system includes determining paths between a subset of certificate of the system and at least one trust root, storing each of the paths in a table prior to a request for path validation information, and fetching the validation information stored in the table in response to a request for path validation information. Providing path validation information may also include digitally signing the validation information. Providing path validation information may also include applying constraints to the validation information and only providing validation information that is consistent with the constraints. Determining paths may include constructing a directed graph of trusted roots and the subset of certificates and performing a depth-first acyclic search of the graph.

摘要： Indicating data currentness (20) includes, on any date of a sequence of dates, issuing a proof indicating the currentness status (24) of the data during a particular time interval. The proof may be a digital signature (22). The time interval may be in the form of a current date and an amount of time. The proof may include a digital signature of the time interval. The proof may include a digital signature of the time- interval and the data. The proof may include a digital signature of the time interval and a compact form of the data, such as a hash. Indicating data currentness may also include distributing the proofs to a plurality of unsecure units that respond to requests by users for the proofs. Indicating data currentness may also include gathering a plurality of separate pieces of data and providing a single proof for the separate pieces of data. The data may be electronic documents.

摘要： Facilitating a transaction between a first party and a second party includes, prior to initiating the transaction, one of the parties obtaining an artificially pre-computed OCSP response about a specific digital certificate, where the artificially pre-computed OCSP response is generated by an entity other than the first party and the second party, one of the parties initiating the transaction, in connection with the transaction, the first party providing the specific digital certificate to the second party, and the second party verifying the specific digital certificate using the artificially pre-computed OCSP response. The second party may obtain the artificially pre-computed OCSP response prior to the transaction being initiated. The second party may cache the artificially pre-computed OCSP response for future transactions. The first party may obtain the artificially pre-computed OCSP response prior to the transaction being initiated. The first party may cache the artificially pre-computed OCSP response for future transactions.

摘要： A validation module provides for the upgrading of a physical access control system (PACS) to full HSPD-12 compliance without requiring modification or replacement of the existing PACS. The validation module may contain all of the validation functionality required by federal specifications and technical requirements. The validation module may be installed between an existing PACS panel and a supported card/biometric reader. Readers may be selected based on assurance level requirements, e.g., contactless or contact readers for low and medium assurance level areas and full biometric readers for high assurance areas. The validation module may validate a card according to the assurance level setting, extract ID information from data on the card and then pass the ID information to the PACS panel for an access decision. Cardholder data captured by one validation module may be distributed to other validation modules of the PACS using a management station.
