RTCA DO-326A, titled “Airworthiness Security Process Specification,” provides guidance for handling the threat of intentional, malicious interference with aircraft systems and outlines compliance objectives and data requirements for aircraft and airborne equipment manufacturers.
Latency is different from determinism, which is knowing exactly when an instruction will execute. It’s an important distinction to be aware of when building embedded systems.
In applications where data flows need to take place in nanoseconds, the delay between when an instruction is received and when it executes, known as latency, is very important.
When it comes to protecting classified data, each encryption standard has a testing authority and an approval authority. This blog talks about the most influential and well-known standards for securing data-at-rest (DAR) and what it takes to protect classified information.
The Data-At-Rest Encryption Series white papers provide engineers, system architects, and program managers with background information, technical details, and a methodology for selecting a data-at-rest (DAR) security approach.
Because optical connections transmit data using light, they don’t radiate signals that can be intercepted. Security for traditional copper Ethernet connections can now be significantly enhanced, however, thanks to end-to-end encryption standards.
The electrical charge stored in a flash memory cell degrades over time, and will degrade much faster at extended temperatures. This degradation has been modelled to follow the Arrhenius Equation, degrading exponentially as temperature rises.
Looking for the latest on Trusted Computing for aerospace and defense? Our white paper series, Trusted Computing: The COTS Perspective, examines the technologies and trends protecting today’s critical systems from cybersecurity and physical threats.
There’s an art to selecting the right COTS system integration partner. When system integrators partner with the right solution vendor, they gain access to the capabilities, skills, and knowledge that comes from decades of experience.
There are two primary types of non-volatile flash memory devices in use today: NOR and NAND flash. Below we look at the differences between NAND and NOR flash devices, and explore types of NAND flash, including SLC, MLC, and TLC.
