Cleanroom Methodology
Cleanroom Methodology: A rigorous software development process aimed at producing defect-free software by applying engineering principles of process control and quality assurance. It emphasizes formal specification, incremental development, and statistical quality control to iteratively refine the software.
CIA Triad
CIA Triad: A widely-used information security model that represents the three fundamental principles of security – Confidentiality, Integrity, and Availability. Confidentiality is about protecting information from being accessed by unauthorized parties, integrity ensures that the information is accurate and hasn’t been improperly modified, and availability ensures that the information is accessible to authorized users when […]
Cleartext
Cleartext: Data that is transmitted or stored unencrypted and thus can be easily read and understood without any need for decryption. While it facilitates ease of use and interoperability, it poses significant security risks as it can be easily intercepted and read by unauthorized individuals, potentially leading to data leakage, privacy violations, or other security […]
Cipher Block Chaining (CBC) Mode
Cipher Block Chaining (CBC) Mode: A mode of operation for block ciphers where each block of plaintext is XORed with the previous ciphertext block before being encrypted. This method ensures that identical plaintext blocks will encrypt to different ciphertext blocks, enhancing security. It uses an initialization vector (IV) for the first block to ensure randomness.
Client/Server Network
Client/Server Network: A network architecture where multiple client devices or programs connect to centralized servers to access services, resources, or share data. Servers provide various functionalities – like email, file storage, or web page hosting – while clients make requests to servers to utilize these services. This model is foundational to modern computing and the […]
Cipher Feedback (CFB) Mode
Cipher Feedback (CFB) Mode: A mode of operation for block cipher systems that effectively converts a block cipher into a self-synchronizing stream cipher. In CFB mode, the previous ciphertext block is encrypted, and the output is XORed with the current plaintext block to get the current ciphertext block. As with CBC mode, the chaining mechanism […]
