- "In cryptography, encryption is the process of encoding information."
The process of converting encrypted data back into its original, readable form.
Cryptography: The study of secure communication techniques.
Encryption: The process of encoding a message or information in a way that only authorized parties can access it.
Decryption: The process of transforming encoded information back into its original form.
Cryptographic Algorithms: A set of rules or procedures used to encrypt or decrypt data.
Symmetric Key Encryption: Encryption technique that uses a single key for both encryption and decryption.
Asymmetric Key Encryption: Encryption technique that uses two keys, one public and one private, for encryption and decryption.
Digital Signature: An electronic method of verifying the authenticity of digital data.
Key Management: The process of generating, distributing, and storing keys securely.
Hashing: A technique used to produce a fixed-length representation of a message or data set.
Brute Force Attack: An attack in which an attacker tries all possible passwords or keys to decode the encrypted data.
Cryptanalysis: The study of the methods used to decode or break encrypted messages.
Malware: Software designed to harm or steal sensitive data from a computer system.
Cross-Site Scripting (XSS): An attack in which attackers inject malicious code into a website to steal sensitive information.
SSL/TLS: Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are cryptographic protocols used to secure web communication.
Public Key Infrastructure (PKI): A set of tools, protocols, and standards used to manage public key encryption.
Quantum Cryptography: A cryptographic technique that uses quantum mechanics to generate and distribute keys.
Symmetric Encryption: A type of cryptography that uses the same secret key for both encryption and decryption.
Asymmetric Encryption: A type of cryptography that uses two different keys – a private key for decryption and a public key for encryption.
Hashing: A process of generating a fixed-size, unique message digest from an input data. It is not reversible, making it useful for validating data integrity.
RSA Encryption: A widely used algorithm for asymmetric encryption, based on the principle of prime factorization.
Blowfish Encryption: A symmetric-key algorithm that uses complex encryption functions and key-lengths up to 448 bits.
AES Encryption: A widely used symmetric encryption algorithm that is highly secure due to its key-lengths up to 256 bits.
DES Encryption: A symmetric encryption algorithm developed by IBM in the 1970s, widely used in legacy systems.
TripleDES Encryption: A more secure version of DES that encrypts a message three times with three different keys.
One-Time Pad: An encryption technique that uses a random key that is as long as the message, known only to the sender and receiver.
Elliptic Curve Cryptography: A type of asymmetric encryption that uses elliptic curves instead of prime factorization, providing stronger security with shorter key lengths.
- "This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext."
- "Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information."
- "Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor."
- "For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm."
- "It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required."
- "An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users."
- "Early encryption techniques were often used in military messaging."
- "Modern encryption schemes use the concepts of public-key and symmetric-key."
- "Modern encryption techniques ensure security because modern computers are inefficient at cracking the encryption."
