摘要： In an intermittently operative phase-locked loop, in order to prevent the oscillator frequency from significantly changing at the time of turning on of an electric power source, a point in time at which a phase difference between clock signals respectively fed to a reference frequency divider and to a frequency divider for dividing the output frequency of a voltage-controlled oscillator becomes substantially zero is detected, and the two frequency dividers are initialized when the above-mentioned point in time is detected after turning on of the electric power source.

摘要： This invention relates to a phase coincidence detector for examining whether or not two input digital signals are coincident by utilizing a delay signal and an advance signal of a digital phase comparator which examines the phase difference between the two input digital signals and outputs the delay signal representing the delay of one of the input signals to the other and the advance signal representing the advance of one of the input signals to the other. Particularly, the output signals of the phase comparator, that is, the delay signal and the advance signal, are periodic pulse signals, and residual pulses having a small pulse width occur periodically even at the time of coincidence. The phase coincidence detector of this invention changes the delay and advance signals by a pulse width discrimination circuit for discriminating whether or not the phase difference between the two input signals is below a certain constant value, and samples the changed signals to output the in-phase and out-of-phase state as signals having different levels.

摘要： A person authentication system capable of performing personal authentication by comparing templates that is personal identification data with sampling information input by a user is disclosed. For example, a service provider (SP) or a user device (UD) acquires the templates from a person identification certificate (IDC) generated by a personal identification certificate authority that is a third party to thereby perform personal authentication. The IDC stores data, such as a certificate identifier and a user identifier, in accordance with a format, and also stores encrypted templates in a manner that the data can be decrypted by an entity that performs authentication. This arrangement achieves efficient template retrieval and a personal authentication process, as well as effective prevention of the templates from being leaking out.

摘要： Disclosed are a person authentication system, a person authentication method, and an information processing apparatus which allow person authentication to be performed in an easy fashion in various devices by comparing a template serving as person identification data with sampling information input by a user. A service provider (SP) or user device (UD) executes person authentication by acquiring a template from a person identification certificate (IDC) generated by a third-party agency serving as a person identification certificate authority (IDA). The IDA acquires a template serving as identification data after verifying a person requesting an IDC to be issued, and generates the IDC storing template information. The IDA distributes the IDC having a digital signature of the IDA added thereto to the SP and the UD.

摘要： The present invention provides a novel configuration which allows devices capable of processing different signature algorithms to mutually verify public key certificates. In this configuration, public key certificates storing plural signatures based on different signature algorithms such as RSA and ECC are issued and each device selects a signature which can be processed (namely, verified) by itself and verifies the selected signature. Consequently, the novel configuration allows the devices each being capable of verifying only a different signature algorithm to verify the public key certificates of the other devices, so that each device can perform public key certificate verification in the cross-certification and encrypted data communication not only with the other devices having public key certificates attached with signatures based on the same signature algorithm as that of each device, but also with the other devices or providers having public key certificates attached with signatures based on different signature algorithms from that of each device, thereby significantly enhancing the reliability in communication.
