Abstract: PROBLEM TO BE SOLVED: To provide a method for an entity to control access of a plurality of users to at least one unconnected door. SOLUTION: The users are mapped into groups. Digital signatures SIGUDd indicating that members of the group has access to the door during a period d is generated by an approval organ per the period d of a series of dates. The SIGUDd to be presented to the door is handed to at least one member of the group for the period d to pass the door. The at least one member of the group is to present the SIGUDd to the door D. The SIGUDd is a digital signature of the approval organ indicating that the members of the group is allowed to access the door during the period d. The door is opened after verifying that the present time is within the period d. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: A cost-effective system that provides for the efficient protection of transmitted non-public attribute information may be used, for example, to control access to a secure area. Encryption of the attribute information may be performed using symmetric encryption techniques, such as XOR and/or stream cipher encryption. A centralized database that stores and transmits the encrypted attribute information may generate the encryption/decryption key based on selected information bytes, for example, as taken from a card inserted into a handheld device used at the secure area. The selected information to generate the encryption key stream may be varied on a periodic basis by the centralized database. Information as to which selected bytes are to be used for a particular access authorization request may be transmitted to the handheld unit or may be input through action of a user of the handheld unit, for example by entry of a PIN code.
Abstract translation: 可以使用提供有效保护所传送的非公开属性信息的具有成本效益的系统，例如来控制对安全区域的访问。 可以使用诸如XOR和/或流密码加密之类的对称加密技术来执行属性信息的加密。 存储和发送加密的属性信息的集中式数据库可以基于所选择的信息字节生成加密/解密密钥，例如从插入到安全区域使用的手持设备的卡中取出。 用于生成加密密钥流的所选择的信息可以由集中式数据库周期性地改变。 用于特定访问授权请求的哪些选定字节的信息可以被发送到手持式单元，或者可以通过手持式单元的用户的动作来输入，例如通过输入PIN码。

Abstract: Actuating a security system (30) includes providing a first set of access codes to a wireless device (32) and causing the wireless device (32) to transmit the first set of access codes to a first controller (26) that actuates the security system (30) . The first set of access codes provided to the wireless device (32) may expire. Actuating a security system (30) may also include providing expiration dates for each of the first set of access codes provided to the wireless device (32) . Actuating a security system (30) may also include examining each of the expiration dates and, in response to a particular expiration date being prior to a current date, erasing from the wireless device (32) a particular one of the first set of access codes that corresponds to the particular expiration date.

Abstract: Indicating data currentness includes, on any date of a sequence of dates, issuing a proof indicating the currentness status of the data during a particular time interval. The proof may be a digital signature. 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.

Abstract: 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.
Abstract translation: 公开了一种用于通过数字证书验证过程来控制物理访问的系统和方法，所述数字证书验证过程使用标准证书格式，并且使得认证机构（CA）可以在任何时间间隔（例如，每天， 小时或分钟），从C的发行日期开始，D1。 C的时间粒度可以在证书本身内指定，除非对所有证书是相同的。 例如，所有证书可能具有一天的粒度，每个证书在发布后365天到期。 给定由CA提供的某些初始输入，单向散列函数用于计算数字证书中包含的指定字节大小的值，并计算保密并在验证过程中使用的其他值。
