Meaning and Definition
A suite of cryptographic algorithms needed to implement a particular security service, including key generation, encryption, and decryption.
A complete framework for secure communication, encompassing protocols, algorithms, and the infrastructure to manage cryptographic keys and processes. It is often associated with specific implementations like RSA, AES, or PGP.

FAQ
Frequently Asked Questions
No. A cryptosystem is a general term for any system that uses cryptography (e.g., SSL/TLS for web security, PGP for email). Cryptocurrency is a specific application that uses cryptosystems (like blockchain and digital signatures) for a decentralized financial system.
An encryption algorithm (like AES) is a single mathematical procedure for scrambling data. A cryptosystem is the complete package, which includes one or more encryption algorithms, methods for key generation, key distribution, decryption, and often digital signatures.
Yes. A cryptosystem is considered broken when a method is found to decrypt messages without the legitimate key, using less time or computational resources than theoretically predicted. This can be due to algorithmic flaws, implementation errors, or advances in computing (e.g., quantum computers).
Yes. These are the two main classes. Symmetric cryptosystems (e.g., AES) use the same key to encrypt and decrypt. Asymmetric cryptosystems (e.g., RSA) use a public key for encryption and a separate private key for decryption, solving the key distribution problem.
A suite of cryptographic algorithms needed to implement a particular security service, including key generation, encryption, and decryption.
