Study Notes
- There are different ways to distribute public keys, such as public announcement, public directory, public-key authority, and public-key certificates.
- A trusted organization is responsible for maintaining and distributing the public directory.
- Secure and authenticated communication is mandatory in distributing public keys.
- X.509 defines a framework for authentication services by the X.500 directory to its users.
- X.509 recommends RSA but does not dictate a specific hash algorithm.
- Each X.509 certificate contains a user's public key signed with the private key of a trusted certification authority.
- The format of an X.509 certificate includes various elements such as version, serial number, signature algorithm identifier, issuer name, and subject name.
- User certificates generated by a CA are unforgeable and can be placed in a directory without special protection.
- PKI is defined by NIST and has requirements such as verifying the certificate's owner, origin, and currency.
- PKI components include end entity, CA, RA, repository, and replying party.
