What Is the Role of Session Keys in Symmetric Cryptography, and How Are They Used to Secure a Single Financial Transaction?

A session key is a symmetric key that is used to encrypt the communication for a single session or transaction. The session key is typically generated randomly at the beginning of the session and is discarded at the end of the session.

This ensures that even if a session key is compromised, it cannot be used to decrypt past or future communication. In the context of a financial transaction, a session key can be used to encrypt the communication between the customer and the financial institution, protecting the sensitive financial data from eavesdropping.
