Understanding Modern Cryptography
What is Cryptography?
Cryptography is the science and art of securing communication and information from adversaries. It involves techniques for encoding messages so that only authorized parties can access or understand them. The main objectives of cryptography include:
1. Confidentiality: Ensuring that information is accessible only to those authorized to have access.
2. Integrity: Protecting information from being altered or tampered with by unauthorized individuals.
3. Authentication: Verifying the identities of the individuals involved in communication.
4. Non-repudiation: Ensuring that a sender cannot deny sending a message, and a receiver cannot deny receiving it.
Evolution of Cryptography
Modern cryptography has evolved significantly over the years, transitioning from classical methods, such as substitution and transposition ciphers, to sophisticated algorithms that make use of complex mathematical concepts. The advent of computers has further transformed cryptographic practices, enabling the development of:
- Symmetric Key Cryptography: This involves a single key for both encryption and decryption. Examples include the Advanced Encryption Standard (AES) and Data Encryption Standard (DES).
- Asymmetric Key Cryptography: This employs a pair of keys – a public key for encryption and a private key for decryption. RSA and Elliptic Curve Cryptography (ECC) are popular examples.
- Hash Functions: These are used to generate a fixed-size string of characters (the hash) from input data of any size, ensuring data integrity. SHA-256 is a well-known hash function.
