摘要： An optical sensor includes a first illuminating system, a second illuminating system, a first regular reflected light detection system, a second regular reflected light detection system and so forth. The first illuminating system is disposed at the −X side of the opening in the dark box, and the second illuminating system is disposed at the +X side of the opening in the dark box. The first and second illuminating systems emit light to the opening. The incidence angles of irradiation light from the first and second illuminating systems relative to the surface of the stage are set equal to each other. The first regular reflected light detection system detects the light emitted from the first illuminating system and regularly reflected by the recording paper, and the second regular reflected light detection system detects the light emitted from the second illuminating system and regularly reflected by the recording paper.

摘要： A media-independent handover key management architecture is disclosed that uses Kerberos for secure key distribution among a server, an authenticator, and a mobile node. In the preferred embodiments, signaling for key distribution is based on re-keying and is decoupled from re-authentication that requires EAP (Extensible Authentication Protocol) and AAA (Authentication, Authorization and Accounting) signaling similar to initial network access authentication. In this framework, the mobile node is able to obtain master session keys required for dynamically establishing the security associations with a set of authenticators without communicating with them before handover. By separating re-key operation from re-authentication, the proposed architecture is more optimized for a proactive mode of operation. It can also be optimized for reactive mode of operation by reversing the key distribution roles between the mobile node and the target access node.

摘要： According to an embodiment, a communication apparatus establishes communication with an external apparatus through a higher-level device. The communication apparatus includes a main processor and a key generator. The main processor receives a data authentication request including data to be authenticated, a first key specification, and a message authentication algorithm identifier from the higher-level device. The key generator retains a key hierarchy used by an authentication protocol that is used between the higher-level device and the external apparatus, and to generate a first key by use of the key hierarchy and the first key specification. The main processor generates a message authentication code for the data to be authenticated by use of the message authentication algorithm, which is identified by the message authentication algorithm identifier, and the first key, and transmits a data authentication response including the message authentication code to the higher-level device.
