Cryptology groups together by definition of Cryptography and Cryptanalysis. For the scope of this taxonomy, under this sub-domain fall the mathematical aspects of cryptology, the algorithmic aspects, their technical implementation and infrastructural architectures as well as the implementation of cryptanalytic methodologies, techniques and tools. Furthermore, this domain also considers digital steganography, which is a technique for concealing information in a particular digital format.
The subdomains for this knowledge domain are:
- Asymmetric cryptography
- Symmetric cryptography
- Cryptanalysis methodologies, techniques and tools
- Functional encryption
- Mathematical foundations of cryptography
- Crypto material management (e.g. key management, PKI)
- Secure multi-party computation
- Random number generation
- Digital signatures
- Hash functions
- Message authentication
- Quantum cryptography
- Post-quantum cryptography
- Homomorphic encryption
