Perfect forward secrecy (or PFS) is a process in which an encryption system regularly changes its encryption keys, so only a tiny bit of data can be compromised in any single breach. The system switches keys after every message, call, or page load. This means that an interceptor can only get hold of that one operation or message, but not all the other data, as it is encrypted by different sets of keys. How does perfect forward secrecy work? Let’s say two people are chatting via a secure messaging app that uses PFS. The app uses public and private keys, which encrypt their communication and identifies them as intended senders and receivers. It uses these keys only to help them to identify one another. Then a key exchange algorithm creates an ephemeral key, which encrypts every single message. When one person send a message to another, it will be encrypted with that key. The receiver decrypts it using the same key. Similar process is repeated in every exchange of messages. Each message has new session keys. Now even if a hacker intercepts this conversation, they’ll only be able to see a single message rather than the whole conversation. *** 📌OUR SOCIAL MEDIA 📱 🔵FACEBOOK: https://www.facebook.com/NordVPN/ 🔵INSTAGRAM: https://www.instagram.com/nordvpn/ 🔵TIKTOK: https://www.tiktok.com/@nordvpn 🔵TWITTER: https://twitter.com/NordVPN Check out NordVPN’s German and French channels ⏯️ 🌐 🇫🇷 @NordVPNenfrancais 🇩🇪 @NordVPNaufDeutsch #PFS #ForwardSecrecy #PerfectForwardSecrecy
