In a cryptography system, client and server terminals each generate a private key constituting a randomized compilation of dynamic system parameters. Public keys are then generated based on the private keys, exchanged between the terminals, and used to generate a shared secret. Key stream generators generate a randomized key stream at each terminal using the shared secret, based on self-generating primitive polynomials. Key length is user selected, and may be modified during an ongoing encryption session. The generator includes a plurality of linear feedback shift registers whose lengths are self-configuring based on the user-specified key length. The registers are interconnected so that their output, namely, the key stream, is non-linear and random. Data is converted to binary form and encrypted by XOR'ing the binary-format data with the key stream. The system may be used in both a static secure transfer mode and a dynamic secure real time transfer mode.

This invention relates to methods and devices for time synchronization. The invention has particular application in the alignment of slave clocks to a master clock and in dealing with packet delay variation and dynamic asymmetries in the network links between them. In embodiments of the invention, the slave clock uses the peer link delay and residence times measured by peer-to-peer transparent clocks to compensate for clock synchronization errors that arise due to variability in message transfer delays. Embodiments provide a simple linear approximation technique and a Kalman filter-based technique for estimating offset and skew of the slave clock.

A method and apparatus provide high-sensitivity GPS/GNSS signal acquisition in a stationary GPS/GNSS receiver. The uncertainty in frequency due to apparent Doppler shift is partitioned into a plurality of contiguous frequency bins, and the uncertainty in location of navigation data bit boundaries is partitioned into equally spaced trial bit boundary locations. For each combination of the trial bit boundary location and the frequency bin, a signal block of captured complex baseband signal is Doppler-compensated using a phase rotator, and then synchronously summed with a periodicity of one period of C/A code so as to produce a compressed sample block having N samples. Each compressed sample block is cross-correlated with one period of reference C/A code to produce an N-value correlation function. A predetermined number of magnitudes of the N-value correlation functions are stack-accumulated into an array with precession compensation so as to find a correlation peak having the largest value.

The present invention generally relates to methods and apparatus for precision time transfer wherein the inherent packet delay variation and possible asymmetry introduced in networks is avoided or mitigated. In one embodiment, the timing functions of a master device may be placed closer to a slave device using a Remote Time-Stamp Generator, located in the network between the master and the slave, and whose time reference serves as a proxy for the time reference of the master. Time-of-traversal of packets at the remote time-stamp generator may be used as proxies for the time-of-departure and the time-of-arrival of certain messages at the master. Such proxy times may be used to synchronize the slave with the master, particularly if the master and the Remote Time-Stamp Generator are both synchronized with a Global Navigation Satellite System (GNSS) source.
