The CIA Triad in Cryptography
The CIA triad—Confidentiality, Integrity, and Availability—is the cornerstone of information security and cryptography. Each component addresses a key aspect of securing information:
Confidentiality: Ensures that data is accessible only to authorized individuals. Cryptographic methods like encryption are used to protect sensitive data from unauthorized access.
Integrity: Guarantees that the data remains unchanged from its original form during storage or transmission. Techniques like hash functions verify the integrity of the data.
Availability: Ensures that authorized users can access the data or system when needed. Although availability is not directly enforced by cryptography, cryptographic protocols must not impede legitimate access.
The CIA triad forms the foundation of cryptographic objectives and helps in designing secure systems.
