Ring learning with errors key exchange 1970-01-01
Ring Learning With Errors (Ring-LWE) is a crucial concept in modern cryptography, particularly in the realm of post-quantum cryptography. It is built upon the Learning With Errors (LWE) problem, which is a well-known problem believed to be hard to solve even for quantum computers. The Ring-LWE problem leverages the structure of polynomial rings, making it more efficient than standard LWE while maintaining similar levels of security.
Black bag operation 1970-01-01
A "black bag operation" refers to a covert operation in which individuals, typically spies or intelligence agents, break into a facility, home, or secure location to gather information, retrieve sensitive documents, or plant listening devices. This term often implies clandestine activities that are carried out without the permission or knowledge of the target.
