Tagged is a social networking website that was launched in 2004. It allows users to create profiles, connect with friends, share photos, and interact with other users through various social features. Originally, Tagged was designed to help people meet new friends and expand their social circles, particularly emphasizing casual connections. One of the notable features of Tagged is its emphasis on games and entertainment, which includes social games that users can play with one another.
The term "Cryptographic High Value Product" (CHVP) is not a widely recognized or standardized term in the field of cryptography or technology as of my last training cut-off in October 2023. However, it can be inferred to refer to products that utilize cryptographic techniques to provide high levels of security or protection for valuable information or transactions.
A Cryptographic Module Testing Laboratory is an accredited facility that evaluates and tests cryptographic modules to ensure they meet specific security standards and compliance requirements. These modules, which can include hardware or software implementations of cryptographic algorithms, are essential for protecting sensitive information through various techniques, such as encryption, decryption, digital signatures, and key management.
"Harvest now, decrypt later" typically refers to a cybersecurity strategy or an approach used by hackers. It involves collecting or harvesting sensitive data (like passwords or personal information) from various sources or systems while ensuring that the data is stored in an encrypted format. The idea is to capture this information swiftly during an attack and then decrypt it later when it might be more advantageous, such as when the attackers have more resources or when the data's value increases over time.
HashClash is a term primarily associated with a cryptographic attack involving hash functions, specifically targeting the SHA-1 (Secure Hash Algorithm 1) hash function. Researchers demonstrated that it is possible to generate two different sets of data that produce the same SHA-1 hash value, which is known as a hash collision. This discovery significantly weakened the security of SHA-1, as it allowed attackers to craft malicious files that could be indistinguishable from legitimate files in terms of their hash values.
Hashgraph is a distributed ledger technology that offers an alternative to traditional blockchain mechanisms. It was developed by Dr. Leemon Baird and is designed to provide a more efficient and scalable way to achieve consensus among distributed nodes in a network.
Honey encryption is a cryptographic technique designed to provide security against specific types of attacks on encrypted data, particularly chosen-plaintext attacks and brute-force attacks. The concept was introduced by Ran Canetti, Yuval Ishai, and Eyal Kushilevitz in 2016.
Human rights and encryption are interconnected concepts that address privacy, security, and freedom in the digital age. Here's an overview of each concept and their relationship: ### Human Rights Human rights are the fundamental rights and freedoms that belong to every person, regardless of nationality, sex, ethnicity, religion, or any other status. These rights are often enshrined in international law through documents such as the Universal Declaration of Human Rights (UDHR) adopted by the United Nations in 1948.
In cryptography, a **hybrid argument** typically refers to a methodology used to prove the security of cryptographic constructions, especially in the context of protocols that involve both symmetric and asymmetric cryptography. The hybrid argument is primarily used in the context of security proofs, particularly in regard to the security of cryptographic schemes against specific types of attacks.
A hybrid cryptosystem is a cryptographic system that combines the strengths of both symmetric and asymmetric (public-key) encryption to secure communications. This approach leverages the efficiency of symmetric encryption for bulk data encryption while using asymmetric encryption for secure key exchange. ### Key Features: 1. **Symmetric Encryption**: - Fast and efficient for encrypting large amounts of data. - Uses a single secret key for both encryption and decryption.
ISO/IEC 19790 is an international standard that provides a framework for the security requirements and evaluation of cryptographic modules. The standard outlines the criteria that cryptographic modules must meet to ensure their security and reliability in various applications, particularly in governmental and commercial sectors. ISO/IEC 19790 is designed to ensure that cryptographic modules achieve a high level of security by specifying requirements related to: 1. **Security Policy**: Defining a clear security policy for the cryptographic module.
**Trojan.Win32.DNSChanger** is a type of malware that targets Windows operating systems, specifically designed to manipulate the Domain Name System (DNS) settings on infected computers. The primary goal of this Trojan is to redirect users to malicious websites without their consent. Here are some key characteristics: 1. **DNS Manipulation**: The malware alters the DNS settings so that when a user tries to access a legitimate website, they are instead redirected to a malicious or fraudulent site.
Decipherment is the process of interpreting or making sense of a text, message, or code that is in a form that is not immediately understandable. This can involve translating languages, decoding encrypted messages, or interpreting complex symbols and signs. The term is often used in contexts such as archaeology (deciphering ancient scripts), cryptography (breaking codes), and linguistics (translating ancient or obscure languages).
Deniable encryption is a cryptographic technique that allows a sender or recipient of a message to deny having sent or received that message, even if they are compelled to reveal information about it. This means that, under certain conditions, it should be possible to convince a third party that the message does not exist, or that another person could have been the sender or recipient.
A designated verifier signature is a cryptographic concept that allows an individual to create a digital signature that can be validated by a specific set of recipients or a particular verifier, rather than being publicly verifiable. This contrasts with traditional digital signatures, where anyone with access to the signature and the original data can verify its authenticity.
The Dining Cryptographers problem is a thought experiment in cryptography that illustrates the concept of privacy and secure communication in a distributed setting. It was first introduced by David Chaum in 1988. The problem involves a scenario where a group of cryptographers wants to communicate regarding the payment of a dinner bill without revealing who pays for it, ensuring the privacy of individuals while still confirming that someone is paying. ### Scenario: - Imagine a group of three cryptographers dining together.
A diplomatic bag, also known as a diplomatic pouch, is a type of bag or container used by diplomats and embassies to transport official documents, correspondence, and sometimes sensitive materials securely and without interference from local authorities. These bags are protected by international law, specifically the Vienna Convention on Diplomatic Relations of 1961, which grants them certain privileges and immunities.
Direct Anonymous Attestation (DAA) is a cryptographic protocol designed to enable secure and anonymous authentication, particularly in the context of hardware security modules such as Trusted Platform Modules (TPMs). The primary purpose of DAA is to allow a TPM to prove to a verifier (like an online service or another system) that it is a genuine, certified TPM without revealing its identity or the identity of the user it is serving.
The discrete logarithm is a concept from number theory that deals with finding the exponent (logarithm) in a finite group, typically the multiplicative group of integers modulo a prime number.
