## Public-Key Signatures

Updated on 10-Jan-2023 10:46:15
What is a Public Key Signature? A public key signature is a type of digital signature that uses a pair of keys – a public key and a private key – to authenticate the sender of a message. The private key is kept secret by the sender and is used to create the signature, while the public key is made available to anyone who wants to verify the signature. Public key signatures are based on the principles of public key cryptography, in which a message encrypted with a public key can only be decrypted with the corresponding private key. This ...

## Symmetric-Key Signatures

Updated on 10-Jan-2023 10:40:04
What is a Symmetric Key? A symmetric key is a type of cryptography in which the same secret key is used for both encrypting and decrypting a message. It is also referred to as a shared secret because both the sender and the recipient of the message must have the key in order to be able to encrypt and decrypt the message. Symmetric key algorithms are fast and efficient, but they require that both the sender and the recipient of the message have a copy of the key in advance. This can be a challenge in situations where the sender ... Read More

## Symmetric Key Algorithms

Updated on 10-Jan-2023 10:36:58
What is Symmetric Key Algorithms? Symmetric key algorithms are a type of cryptographic technique that uses a shared secret key for both encryption and decryption. This means that the same key is used to encode and decode the message. Symmetric key algorithms are generally faster and more efficient than asymmetric key algorithms, but they require that the sender and receiver of a message share a secret key. Here are some of the basic principles of symmetric key algorithms − The same key is used for both encryption and decryption − In symmetric key algorithms, the same key is used ... Read More

## Quantum Cryptography

Updated on 10-Jan-2023 10:15:27
What is Quantum Cryptography? Quantum cryptography is a field of study that focuses on the use of quantum mechanical phenomena, such as superposition and entanglement, to secure communication. Quantum cryptography involves the use of quantum states to encode and transmit information, and it is based on the principles of quantum mechanics. One of the main advantages of quantum cryptography is that it can provide unconditional security. This means that it is theoretically impossible for an attacker to intercept and decrypt the transmitted information without being detected. This is because the principles of quantum mechanics ensure that any attempt to intercept ... Read More

## Distributed Hash Tables (DHTs)

Updated on 10-Jan-2023 10:00:31
What Is a Distributed Hash Table? A distributed hash table (DHT) is a type of distributed system that provides a lookup service similar to a hash table. In a hash table, data is stored and retrieved using keys, and the keys are used to determine the location of the data in the table. A distributed hash table is similar, but the data is distributed across multiple nodes in a network rather than being stored in a single table. In a DHT, each node is responsible for storing and managing a portion of the data. When a client wants to retrieve ... Read More

## Post Office Protocol, Version 3 (POP3)

Updated on 09-Jan-2023 14:46:57
What is POP3 (Post Office Protocol 3)? Post Office Protocol version 3 (POP3) is a standard protocol used by email clients to retrieve email messages from a mail server. It is a simple, text-based protocol that allows a client to connect to a server, retrieve email messages, and mark them as read or unread. POP3 works by establishing a connection between the email client and the mail server. The client sends a request to the server to retrieve email messages, and the server responds with a list of available messages. The client can then choose which messages to download and ...
