Cryptographic primitives
Cryptographic primitives are the basic building blocks of a security protocol or system. In the following section, you are introduced to cryptographic algorithms that are essential for building secure protocols and systems. A security protocol is a set of steps taken to achieve the required security goals by utilizing appropriate security mechanisms. Various types of security protocols are in use, such as authentication protocols, non-repudiation protocols, and key management protocols.
The taxonomy of cryptographic primitives can be visualized as shown here:
Figure 3.2: Cryptographic primitives
As shown in the preceding cryptographic primitive taxonomy diagram, cryptography is mainly divided into three categories: keyless primitives, symmetric key primitives, or cryptography, and asymmetric key primitives, or cryptography.
Keyless primitives and symmetric cryptography are discussed further in the next section, and we will cover asymmetric...
