 Cryptographic protocol

A cryptographic protocol is a formal set of rules that dictate how data is exchanged and secured between parties using cryptographic techniques. These protocols are designed to ensure confidentiality, integrity, authenticity, and non-repudiation in communications and transactions. Key aspects of cryptographic protocols include: 1. **Encryption**: This involves converting plaintext data into ciphertext to ensure that only authorized parties can read it. Different algorithms, such as AES or RSA, may be used.
