VIII.II

Public Key Infrastructure

In Chapter 4, we have seen different public key cryprography algorithms either for encryption and/or digital signatures. In all of these, remember that there are two keys per user. [more]

Certificate Revocation

If someone realizes his private key has been stolen or if someone gets fired from an organization, it is important to be able to revoke his certificate so that it will no longer be valid. [more]

VIII.IV

Secure Socket Layer (SSL)

Standards for real-time public key based security protocols include IPsec, SSL/TLS, and SSH. SSL/TLS and SSH are implemented at layer 4, whereas IPsec is implemented at layer 3. [more]

VIII.V

IPsec

IPsec is an IETF standard for real-time security on the network layer. [more]
