Caesar cipher
Caesar cipher: A type of substitution cipher that is used to encode messages by shifting each letter in the original message by a fixed number of places in the alphabet. It is a simple and easily breakable cipher but is still sometimes used as a basic form of encryption for simple communication or as a […]
Carlisle Adams/Stafford Tavares (CAST)
Carlisle Adams/Stafford Tavares (CAST): A series of symmetric encryption algorithms, including CAST-128 and CAST-256. Named after their developers, Carlisle Adams and Stafford Tavares, these algorithms are used to secure data during transmission or storage, ensuring confidentiality and preventing unauthorized access. CAST-128 is commonly used in various encryption protocols, including Secure Shell (SSH) and OpenVPN.
Cascading Style Sheets (CSS)
Cascading Style Sheets (CSS): A stylesheet language used for describing the presentation of a document written in a markup language. CSS is commonly used in web development to control the appearance and layout of web pages. Examples of using CSS include defining the font, color, and size of text on a webpage or setting the […]
CBC-MAC (Cipher Block Chaining Message Authentication Code)
CBC-MAC (Cipher Block Chaining Message Authentication Code): A cryptographic algorithm used to ensure data authenticity and integrity by utilizing a block cipher in cipher block chaining mode. It processes input data divided into fixed-size blocks, encrypting each block while chaining them together. The output of the final block becomes the message authentication code (MAC), which […]
Cell Suppression
Cell Suppression: A data protection technique used in statistical databases to ensure the privacy and confidentiality of sensitive information. By intentionally withholding (suppressing) the publication of certain data cells (individual entries or values) in a released table, this method prevents the disclosure of information that could be used to identify individuals or confidential attributes, especially […]
Cell-level Encryption (CLE)
Cell-level Encryption (CLE): A database encryption method that encrypts individual cells, or fields, within a database table, allowing for fine-grained control over access to sensitive data. Each cell can be encrypted with a unique key, which prevents unauthorized users from reading the data while still allowing the database to perform complex queries, as the database […]
