A number of mechanisms are required to create the PKI-enabled services discussed in this chapter. Some of the most important mechanisms are discussed in the following subsections.
Secure communication, because it relies on the core PKI services, requires the mechanisms that make the core services possible. These include digital signatures, cryptographic hash functions, MAC algorithms, and symmetric block ciphers. See Chapter 2, "Public-Key Cryptography," for a discussion of such mechanisms.
Secure time stamping can be implemented in such a way that it requires the presence of one or more trusted time sources for the environment. ...
