One example of deniable encryption is a cryptographic filesystem that employs a concept of abstract "layers", where each layer can be decrypted with a different encryption key. [ citation needed ] Additionally, special " chaff layers" are filled with random data in order to have plausible deniability of the existence of real layers and their ...
public/private key - in public key cryptography, separate keys are used to encrypt and decrypt a message. The encryption key (public key) need not be kept secret and can be published. The decryption or private key must be kept secret to maintain confidentiality. Public keys are often distributed in a signed public key certificate.
The new paradigm is to separate public and private keys again after they have been used, in the case of asymmetric encryption, or to remove the temporary, ephemeral key from the content in the case of symmetric encryption. "Trepidation of Relationship” builds on this concept and refers to the relationships between users in a network. The use ...
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key ...
A public authentication key is the public key of an asymmetric key pair that is used with a public key algorithm to determine the integrity of information and to authenticate the identity of entities, or the source of messages, communication sessions, or stored data. Symmetric data encryption key

While the above definition is specific to an asymmetric key cryptosystem, it can be adapted to the symmetric case by replacing the public key encryption function with an encryption oracle, which retains the secret encryption key and encrypts arbitrary plaintexts at the adversary's request.
It has an entity authentication mechanism, based on the X.509 system; a key setup phase, where a symmetric encryption key is formed by employing public-key cryptography; and an application-level data transport function. These three aspects have important interconnections.
