A cipher is an algorithm used for encrypting and decrypting information, transforming plaintext into ciphertext to secure data from unauthorized access. The security of a cipher depends on its complexity and the secrecy of its key, making it a fundamental component in cryptography for ensuring data confidentiality and integrity.

algorithm used for encrypting and decrypting information

Plaintext refers to any text or data that is readable and understandable without requiring decryption or decoding. It is the original message or data before any encryption process, and ensuring its security is crucial to prevent unauthorized access and data breaches.

plaintext

Ciphertext is the result of encrypting plaintext using an algorithm and a key, rendering the original information unreadable to unauthorized parties. It is a crucial element in securing digital communication, ensuring that sensitive data remains confidential and protected from interception or unauthorized access.

secure data

Unauthorized access refers to gaining entry into a computer system, network, or data without permission, often leading to data breaches or other security incidents. It is a critical security concern for organizations, necessitating robust authentication and monitoring measures to prevent and detect intrusions.

Data confidentiality is the practice of protecting information from unauthorized access and disclosure, ensuring that sensitive data remains private and secure. It is a critical component of information security and privacy, requiring robust encryption, access controls, and policy enforcement to safeguard data throughout its lifecycle.

data confidentiality

Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle, ensuring that it remains unaltered and trustworthy for decision-making and analysis. It is crucial for maintaining the credibility of databases and information systems, and involves various practices and technologies to prevent unauthorized access or corruption.
