- A statistical comparison is provided here for informational purposes only.
- Block ciphers (e.g., AES) are deterministic, and encode plaintext into ciphertext.
- There is a one-to-one relationship between plaintext and its corresponding ciphertext.
- Because of this relationship, statistical analysis of ciphertext is an important first step.
- Other cryptanalysis techniques analyze plaintext and ciphertext taken together, as a pair.
- Emergent File System processes are nondeterministic and do not encode plaintext.
- The relationship between plaintext and data aspects is probabilistic.
- Linear and differential cryptanalysis cannot be applied to data aspects.
- Because data aspects are not ciphertext, other techniques must be used.
- It is necessary but insufficient, for a cryptographic system protecting information to resist breakage.
- Whether a particular output corresponds to a certain plaintext must also remain indeterminable.
- Circumvention of a cryptographic design must also be prevented.
