Variable Key Security Protocol (VKSP) Software Library
The Variable Key Security Protocol (VKSP) Software Library from NXP® is a one-way authentication algorithm with a 128-bit key. It is ideal security for applications which require remote operation, such as remote keyless entry (RKE) systems or garage door openers.

Features
- Very secure protocol with a 128-bit key
- Re-synchronization is not required
- Encryption algorithm is user selectable
- Its modularity and state machine oriented design allows the integration and co-existence of the receiver
- library with other complex modules
- Flexibility, regardless of which microcontroller is used
- Re-use of already developed modules, such as memory drivers and proprietary encryption algorithms
- Increased security with a 128-bit key authentication
- System doesn’t require any kind of count resynchronization
- Time-based variable key
- 254 different commands can be implemented
- Is possible to use a different encryption algorithm for code or execution time reduction
- Layer/interfaces design on both the receiver and transmitter provides user flexibility with different non-volatile memory and encryption drivers
- Receiver is designed as a state machine system, which eases the integration and interaction with other applications
