Study Notes
Symmetric Encryption Key Essentials
- A shared secret key must be shared between two parties for symmetric encryption to work.
- Frequent key changes are usually desirable in symmetric encryption to minimize the impact of a key being compromised.
- The primary concern in key distribution for two parties in data exchange is ensuring the secure exchange of the shared secret key.
- Key distribution technique that involves a third party is known as a trusted third-party protocol.
- The main requirement for symmetric encryption to work between two parties is that both parties must have the same secret key.
