Disclosed is an optical seismic sensor system for measuring seismic events in a geological formation, including a surface unit for generating and processing an optical signal, and a sensor device optically connected to the surface unit for receiving the optical signal over an optical conduit. The sensor device includes at least one sensor head for sensing a seismic disturbance from at least one direction during a deployment of the sensor device within a borehole of the geological formation. The sensor head includes a frame and a reference mass attached to the frame via at least one flexure, such that movement of the reference mass relative to the frame is constrained to a single predetermined path.

Optical seismic sensor systems and methods

Key manager systems and methods for a QKD-based network are disclosed. The system includes a QKD layer that generates quantum encryption keys, a persistent storage layer that stores the quantum encryption keys, and a key management layer. The key management layer generates an application registration record that includes a list of multiple applications that use the quantum encryption keys. The key management layer also generates a corresponding key storage layer. The multiple applications reside in an applications layer. The applications in each node remove keys from the key storage layer so that each node can encrypt/decrypt data using quantum encryption keys. The methods also include secure QKD system boot-up and authentication that facilitate implementing a commercial QKD system in real-world environments.

Key manager for QKD networks

A method of integrating quantum key distribution (QKD) with Internet protocol security (IPSec) to improve the security of IPSec. Standard IPSec protocols impose limits on the frequency at which keys can be changed. This makes efforts to improve the security of IPSec by employing quantum keys problematic. The method includes employing multiple security associations (SA) in in-bound and outbound SA Tables in a manner that enables a high key flipping rate and that enables combining quantum keys with classical keys generated by Internet Key Exchange (IKE), thereby enabling QKD-based IPSec.
