Digital Certificates & Cryptographic Protocols

These flashcards cover key vocabulary terms and their definitions related to Digital Certificates and Cryptographic Protocols.

Asymmetric Cryptography

A type of cryptography that uses a pair of keys: a public key for encryption and a private key for decryption.

Digital Signature Algorithm (DSA)

Protocols that use asymmetric cryptography to verify the identity of the sender.

Digital Certificate

A container for a public key that includes the owner's name, public key, issuer's name, and digital signature of the issuer.

Certificate Authority (CA)

An entity that verifies the authenticity of users requesting digital certificates.

Trust Models

Frameworks that define the trust relationships between entities, including direct trust, third-party trust, and hierarchical models.

Public Key Infrastructure (PKI)

A system for securely creating, storing, exchanging, and managing digital certificates and keys.

Certificate Revocation List (CRL)

A list of digital certificates that have been revoked and are no longer valid.

Nonrepudiation

A property of a digital signature that prevents the sender from denying their signature.

Secure Socket Layer (SSL)

An early cryptographic protocol designed to create an encrypted data path between a client and server.

Transport Layer Security (TLS)

A protocol that replaces SSL, providing secure communication over a computer network.
