A company adopts a new encryption standard that changes keys for each session, preventing the compromise of one key from affecting other sessions. This approach is known as ____________.

The approach where keys change for each session, preventing compromise from affecting other sessions, is known as Perfect Forward Secrecy (PFS). PFS enhances security by ensuring that even if one session key is compromised, it doesn't compromise the security of past or future sessions. Understanding encryption techniques like PFS is essential for secure communication.__________________________________________________
