WebIn cryptography, an oblivious transfer ( OT) protocol is a type of protocol in which a sender transfers one of potentially many pieces of information to a receiver, but remains oblivious as to what piece (if any) has been transferred. WebKY-58. The VINSON KY-58 is a secure voice module primarily used to encrypt radio communication to and from military aircraft and other tactical vehicles. It is employed by U.S. Military Joint Services, NATO and some law enforcement agencies. It is designed to operate over bandwidth-restricted circuits such as UHF and VHF satellite access and ...

Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. Symmetric key ciphers are implemented as either block ciphers or stream ciphers. … WebOct 1, 2024 · Wikipedia gives: "Cryptographic primitives are well-established, low-level cryptographic algorithms that are frequently used to build cryptographic protocols for computer security systems." The problem with that statement is that it seems hard to distinguish between algorithms, primitives, schemes and protocols (in no particular order).
