摘要： Controlling access includes providing a barrier to access that includes a controller that selectively allows access, at least one administration entity generating credentials/proofs, wherein no valid proofs are determinable given 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 in 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： Providing information about digital certificate validity includes ascertaining digital certificate validity status for each of a plurality of digital certificates in a set of digital certificates, generating a plurality of artificially pre-computed messages about the validity status of at least a subset of the set of digital certificate of the plurality of digital certificates, where at least one of the messages indicates validity status of more than one digital certificate and digitally signing the artificially pre-computed messages to provide OCSP format responses that respond to OCSP queries about specific digital certificates in the set of digital certificates, where at least one digital signature is used in connection with an OCSP format response for more than one digital certificate. Generating and digitally signing may occur prior to any OCSP queries that are answered by any of the OCSP format responses. Ascertaining digital certificate validity status may include obtaining authenticated information about digital certificates.

摘要： In an access control system with an entity A, at least one disconnected smart door D that is disconnected from authorities and databases, and users possessing user cards to access smart doors, the method for the disconnected smart door D to indicate to A that a given user U tried to access D generally includes: having D receive from U information IU indicating that U wishes to access the smart door D; having the smart door D at least temporarily store IU; and for at least one subsequent user V, having D cause V to at least temporarily store IU in V's card for presentation to entity A in connection with V's card being used to enter through the door D.

摘要： Un método de control de acceso, que comprende: la utilización de una barrera de acceso provista de un controlador que permite un acceso selectivo; al menos una entidad de administración que genera credenciales de identidad y pruebas de identidad, en donde las credenciales incluyen un valor final y una fecha, en donde el valor final se obtiene aplicando, varias veces, una función unidireccional a un valor aleatorio, estando cada una de las pruebas asociada con un intervalo de tiempo particular, en donde se obtiene diferentes pruebas aplicando la función unidireccional al valor aleatorio, en un número diferente de veces, en donde una prueba que ha de presentarse al controlador en un momento determinado, es el resultado de aplicar la función unidireccional a una prueba a presentarse al controlador en el futuro; el controlador recibe la credencial de identidad de al menos una de las pruebas correspondientes a la tentativa de acceso realizada por un usuario; en respuesta a la tentativa de acceso por el usuario, el controlador determina si el acceso está actualmente autorizado aplicando la función unidireccional a por lo menos una de las pruebas, un determinado número de veces y comparando el resultado con el valor final, correspondiendo el número de veces a una duración de tiempo transcurrido desde la fecha asociada con las credenciales y si el acceso está actualmente autorizado, el controlador autoriza el acceso.

摘要： Determining access includes determining if particular credentials/proofs indicate that access is allowed, determining if there is additional data associated with the credentials/proofs, wherein the additional data is separate from the credentials/proofs, and, if the particular credentials/proofs indicate that access is allowed and if there is additional data associated with the particular credentials/proofs, then deciding whether to deny access according to information provided by the additional data. The credentials/proofs may be in one part or in separate parts. 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 generate proofs. The credentials may correspond to 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.

摘要： At least one administration entity controls access to an electronic device b y the at least one administration entity generating credentials and a pluralit y of corresponding proofs for the electronic device, wherein no valid proofs a re 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 th e particular time, and the electronic device confirming the proof using the credentials. The at least one administration entity may generate proofs afte r 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.
