master key - key from which all other keys (or a large group of keys) can be derived. Analogous to a physical key that can open all the doors in a building. master encryption key (MEK) - Used to encrypt the DEK/TEK key. master key encryption key (MKEK) - Used to encrypt multiple KEK keys. For example, an HSM can generate several KEK and wrap ...
Encrypted Key Exchange (also known as EKE) is a family of password-authenticated key agreement methods described by Steven M. Bellovin and Michael Merritt. [1]
A session key is a single-use symmetric key used for encrypting all messages in one communication session.A closely related term is content encryption key (CEK), traffic encryption key (TEK), or multicast key which refers to any key used for encrypting messages, contrary to other uses like encrypting other keys (key encryption key (KEK) or key encryption has been made public key).
Public key transport keys are the public keys of asymmetric key pairs that are used to encrypt keys using a public key algorithm. These keys are used to establish keys (e.g., key wrapping keys, data encryption keys or MAC keys) and, optionally, other keying material (e.g., Initialization Vectors). Symmetric key agreement key
Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key.
A key management system (KMS), also known as a cryptographic key management system (CKMS) or enterprise key management system (EKMS), is an integrated approach for generating, distributing and managing cryptographic keys for devices and applications. They may cover all aspects of security - from the secure generation of keys over the secure ...
Andrea Pasinetti was out of town when he got the call when a wildfire broke out in Pacific Palisades, where his home and three dogs were. CBS News' Jonathan Vigliotti was reporting nearby.
A key encapsulation mechanism, to securely transport a secret key from a sender to a receiver, consists of three algorithms: Gen, Encap, and Decap. Circles shaded blue—the receiver's public key and the encapsulation —can be safely revealed to an adversary, while boxes shaded red—the receiver's private key and the encapsulated secret key —must be kept secret.
