Cipher 1970-01-01
The term "cipher" can refer to different things depending on the context, primarily in the fields of cryptography and mathematics. Here are the main interpretations: 1. **Cryptography**: In cryptography, a cipher is an algorithm used for encryption or decryption. It transforms readable data (plaintext) into an unreadable format (ciphertext) to protect the information from unauthorized access.
Ciphertext 1970-01-01
Ciphertext is the result of encryption, which is the process of converting plaintext (readable data) into an unreadable format to protect the information from unauthorized access. Ciphertext appears as random characters or sequences of symbols and is typically the output of encryption algorithms. Only someone with the appropriate key or means to decrypt the ciphertext can convert it back into its original plaintext form. This process is fundamental in ensuring data confidentiality and security in various applications, such as secure communications, data storage, and online transactions.
Ciphertext expansion 1970-01-01
Ciphertext expansion refers to the phenomenon where the size of the ciphertext (the encrypted output) is larger than the size of the plaintext (the original message) after a cryptographic operation is performed. This typically occurs in various encryption algorithms and can be a result of several factors: 1. **Padding**: Many encryption algorithms, particularly block ciphers, require the plaintext to be a specific size (often a multiple of a certain block size).
Client-side encryption 1970-01-01
Client-side encryption is a method of data protection in which information is encrypted by the client (the user's device) before being transmitted to a server or cloud storage. This approach ensures that the data remains encrypted while in transit and at rest, meaning that even if a third party, such as the service provider, gains access to the data, they cannot read or interpret it without the encryption keys.
CloudMask 1970-01-01
CloudMask is a specific cloud service or tool designed to assist in cloud-based data management, security, or processing tasks, particularly in the context of cloud storage or data analysis. It allows users to protect sensitive data by masking or anonymizing it, ensuring privacy and compliance with various regulations.
Code (cryptography) 1970-01-01
In the context of cryptography, "code" refers to a method of transforming information in such a way that only authorized parties can understand the original message. Codes are used to conceal the meaning of a message by substituting parts of the message (like words or phrases) with other words, phrases, or symbols. ### Key Features of Codes in Cryptography: 1. **Substitution**: A code replaces words or phrases with predetermined codewords.
Code word 1970-01-01
"Code word" can refer to several concepts depending on the context: 1. **General Definition**: In a broad sense, a code word is a word or phrase used to convey a specific meaning, often understood only by a particular group of people. This can be used for privacy, secrecy, or simplicity in communication. 2. **Military and Security**: Code words are often used in military or security contexts to communicate operational details without disclosing sensitive information to outsiders.
Codebook 1970-01-01
A **codebook** is a document used in research and data analysis to provide a detailed description of the variables and data collected in a study. It serves several important purposes: 1. **Variable Definitions**: It outlines each variable included in the dataset, specifying what the variable represents, its measurement scale (e.g., categorical, ordinal, continuous), and how it was collected.
Codress message 1970-01-01
As of my last update in October 2023, "Codress message" does not appear to refer to a widely recognized concept, term, or product. It could be a new term or concept that has emerged since then, or it might be specific to a certain community, organization, or context.
Colored Coins 1970-01-01
Colored Coins are a type of cryptocurrency that use the Bitcoin blockchain to represent real-world assets or properties. The term comes from the concept of assigning "colors" or attributes to specific satoshis (the smallest unit of Bitcoin), indicating that they have special value or are tied to particular assets beyond just currency.
Communications security 1970-01-01
Communications security (COMSEC) refers to the protective measures and processes that ensure the confidentiality, integrity, and availability of information transmitted over communication channels. It encompasses a variety of techniques and practices designed to safeguard communication systems against unauthorized access, interception, and disruption. Key components of communications security include: 1. **Encryption**: The process of encoding information so that only authorized parties can decode and understand it. This is crucial for protecting sensitive data transmitted over networks.
Completeness (cryptography) 1970-01-01
In cryptography, **completeness** often refers to a property of certain cryptographic protocols or systems, particularly in the context of zero-knowledge proofs and interactive proof systems.
