Abstract: A Secret file access authorization system with fingerprint limitation includes an authorization module, encryption module and certification module in a server linked by programs. A user module of least one client machine contains a kernel encryption/decryption unit embedded in the client operation system kernel, so access authorization to secure files can be limited by environment or time fingerprint. Therein the authorization module provides an authorization secret key (ASK) and fingerprint template. The encryption module accepts the ASK and secret files to be encrypted, and provides a decryption secret key (DSK). The user module accepts the ASK and encrypted secret files, and presents a claim for the ASK certification to the certification module. The certification module accepts the DSK and the claim and the template, and provides the certified DSK for the user module, to start the kernel encryption/decryption unit in the user module, and achieve reading and writing of encrypted files.

The hybrid differential signal, the original clock signal and the original data signal are reduced swing differential signals.

Abstract: A ranging signal R1 generated by a signal generator and reaches to a signal checker via a working system transmission line, a loop circuit, and an auxiliary system transmission line. The signal checker measures a delay time from the generation to the arrival of the signal R1. A ranging signal R2 generated by the signal generator and reaches to a signal checker via an auxiliary system transmission line, a loop circuit, and an auxiliary system transmission line. The signal checker measures a delay time from the generation to the arrival of the signal R12. A delay time of the working system transmission line is calculated from the delay times of the signals R1 and R2. Disruption of the services provided by the other ONUs can be prevented since the working system transmission line is not used for upstream communication of the ranging signals R1 and R2.
