What are Forward secrecy-based protocols

Forward secrecy-based protocols, also known as Perfect Forward Secrecy (PFS), are a class of cryptographic protocols that aim to provide additional security to encrypted communications. The basic idea behind these protocols is that even if an attacker manages to compromise the key to encrypt a message, they cannot decrypt past or future messages that have been exchanged.

To understand how forward secrecy-based protocols work, it’s essential to understand the basics of encryption. Encryption involves transforming a message, or …
