WebCryptographic primitive. Definition (s): A low-level cryptographic algorithm used as a basic building block for higher-level cryptographic algorithms. Source (s): NIST SP 800-175B Rev. 1. Webcryptography is broadly divided into two levels. One with safe cryptographic recipes that require little to no configuration choices. These are safe and easy to use and don’t require developers to make many decisions. The other level is low-level cryptographic primitives. These are often dangerous and can be used incorrectly.

WebAbstract: Quantum conference key agreement is an important cryptographic primitive for future quantum network. Realizing this primitive requires high-brightness and robust multiphoton entanglement sources, which is challenging in experiment and unpractical in application because of limited transmission distance caused by channel loss ... WebA basic construction used within many cryptographic systems is envelope encryption. Envelope encryption uses two or more cryptographic keys to secure a message. Typically, one key is derived from a longer-term static key k, and another key is a per-message key, msgKey, which is generated to encrypt the message.
