    • This specification describes technologies relating to imparting cryptographic information in network communications. In general, aspects of the subject matter described in this specification can be embodied in methods that include identifying a location in a pre-defined portion of a network communication to be sent in a client-server environment, wherein the pre-defined portion is reserved for random data, inserting cryptographic information into the pre-defined portion of the network communication at the location, and sending the network communication in the client-server environment to facilitate modifying interactions in the client-server environment based at least in part on a result of processing of the cryptographic information; and on a receiving side, receiving cryptographic information inserted into the pre-defined portion of the network communication in the client-server environment, identifying the location, processing the cryptographic information, and modifying interactions in the client-server environment based at least in part on a result of the processing.

    • A clock recovery system (10) for recovering an input data signal (14) clock. A rate detector (20) detects the input data signal bit rate and provides range signals (30a-c) specifying progressive ranges encompassing the bit rate. A frequency detector (22) provides a frequency error signal (32) based on frequency difference between the input data signal and a recovered clock signal (16). A phase detector (24) provides a phase error signal (34) based on the input data and recovered clock signals. A filter-controller (26) provides an oscillator driving signal (36) based on the range, frequency error, and phase error signals. An oscillator-divider (28) then provides the recovered clock signal based on the oscillator driving signal and at least some of the range signals. The phase detector, filter-controller, and oscillator-divider collectively thus form a phase locked loop. Optionally, the clock recovery system (10) may also provide a recovered data signal (18).
    • 一种用于恢复输入数据信号(14)时钟的时钟恢复系统(10)。 速率检测器(20)检测输入数据信号比特率,并提供指定包含比特率的逐行范围的范围信号(30a-c)。 频率检测器(22)基于输入数据信号和恢复的时钟信号(16)之间的频率差提供频率误差信号(32)。 相位检测器(24)基于输入数据和恢复的时钟信号提供相位误差信号(34)。 滤波器控制器(26)基于范围,频率误差和相位误差信号提供振荡器驱动信号(36)。 振荡器分频器(28)然后基于振荡器驱动信号和至少一些范围信号提供恢复的时钟信号。 相位检测器,滤波器控制器和振荡器分频器一起形成一个锁相环。 可选地,时钟恢复系统(10)还可以提供恢复的数据信号(18)。
