The boresight correction system determines an angular offset of the sensor boresight relative to the aircraft boresight, allowing for real time or near real time correction for motion or deformation of any data sensed by the aircraft sensor.

An inline encryptor ASIC avoids contaminating memory with data which may be compromised by quantum computers. The inline encryptor ASIC encrypts the data using Post Quantum Cryptography algorithms before storing the data in the memory. The data in the memory is then resistant to quantum computer attacks. The inline encryptor ASIC may sanitize the memory via sanitizing a key used to encrypt the data. Sanitizing the memory by sanitizing the key enables writing CPI data to flash memory without requiring destruction of the flash memory.

The US DoD is moving to incorporate 5G, particularly for sidelinks networks. 5G sidelink network are desired to operate at company, platoon, and squad levels independent of connection to 5G base stations (gNB). The 5G sidelink standards, as defined by 3GPP, cannot operate under active jamming at expected threat levels. The sidelink standards are defined for commercial use and cannot withstand active jamming. Various prior art uses beamforming, directionally beamformed MIMO, and even distributed MIMO as potential options to address active jamming. The SWAP-C and standards of the 5G UEs are not conducive to these anti-jamming techniques. A solution is described that uses the 5G sidelink physical layer with modifications at the control layer to avoid denial of the S-SSB. Intra-, inter-squad, and squad-to-command post communications may use the solution to avoid denial of the 5G sidelink.

PKI Certificates are fingerprinted bi-directionally, replacing traditional certificate exchange in constrained computing and networking environments during a D/TLS session initiation for faster logon to well acquainted peers. Fingerprinting PKI Certificates bi-directionally allows for certificate compression when one or both peers are unacquainted and use of OCSP stapling or OCSP trusted responders offloading validation to robust clusters. A handshake is described for certificate exchange in an OCSP stapling or OSCP with trusted responder environment, and where the network and clients are constrained, which address the deficiencies of the RFC's.

An aircraft-based system for providing forward-looking terrain profiling and downward-looking altimetry via a single active electronically scanned array (AESA) orients the AESA through a sequence of desired directions, e.g., according to a predetermined scan pattern. At each desired direction, the AESA scans for ground-based targets, determining a range and Doppler velocity to each detected target.

Based on the determined ranges and velocities, the radar system determines a pointing angle and vertical/horizontal distances between the aircraft and each identified ground-based target.
