Key distribution center
In cryptography, a key distribution center (KDC) is part of a cryptosystem intended to minimize the risks of exchanging keys and shared secrets.
KDCs often operate in systems when some users may have permission to use certain resources at some times but not at any times.
- Benefits: Easier key distribution and scalability.
- Drawbacks: A KDC can become a single point of failure and every user must trust the KDC administrators
