Cryptography Primitives

Cryptography primitives are nothing but the tools and techniques in Cryptography that can be selectively used to provide a set of desired security services −

  • Encryption
  • Hash functions
  • Message Authentication codes (MAC)
  • Digital Signatures

The following table shows the primitives that can achieve a particular security service on their own.

Note − Cryptographic primitives are intricately related and they are often combined to achieve a set of desired security services from a cryptosystem.
