Title: Explain how confidentiality is achieved through cryptology.
Course: Cybersecurity in Food and Agriculture, Advanced (18204-II) > Section: Examining Cryptology

Explanation should include

- the two fundamental types of encryption
  - symmetric/private key
    - advanced encryption standard (AES)
    - data encryption standard (DES)
  - asymmetric/public key
    - Diffie-Hellman (DH)
    - Rivest-Shamir-Adleman (RSA)
- certificate authorities (CA)
- chain of trust.

Process/Skill Questions:

- Why do businesses still use both symmetric and asymmetric encryption?
- What fundamental encryption-related problem does asymmetric encryption solve?
- How can exhaustive key space search and frequency analysis be used to break encryption?
- How does key length affect the level of security provided by encryption?
