TECHNICAL DEFINITION

A cipher is a cryptographic algorithm that systematically transforms plaintext into ciphertext and back again, leveraging a specific key to ensure data confidentiality and integrity in secure communication and storage systems within cybersecurity architectures.

BACKGROUND

Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.
