Digital Certificates Flashcards

Digital Certificates Overview

• A digital certificate is a password-protected, encrypted data file.
• It serves to verify the identity of the message sender, enhancing security in communication.

Certificate Authority

• Digital certificates are issued by a certificate authority (CA).
• The certificate authority plays a crucial role in ensuring the trustworthiness of digital communications.

Certificate Request Process

• The CA verifies the identity of individuals or companies that submit a certificate request.
• This process helps maintain the integrity and authenticity of the digital certificates issued.

Digital Signature

• A digital signature functions as an electronic stamp for a message.
• It authenticates the message's source and ensures the integrity of its contents.

Non-repudiation

• Digital signatures enforce non-repudiation, providing proof that a transaction took place.
• This concept is essential for accountability in digital interactions, as it prevents denial of the involvement in a transaction.
