Technology
- SyncLock acts on the synchronization of the transmitter with the receiver. If a key other than the secret one is applied the synchronization and the communication fails. A hard-coded error is hidden into the design while the unlocking, i.e., the error correction, takes place at another part of the design upon application of the secret key.
- Advantages: it is generally applicable, incorrect keys result in denial-of-service, it incurs no performance penalty and minimum overheads, and it offers maximum security against all known counter-attacks.
- Uses 1% of the chip’s physical layer surface. Simple plug-in to the DSP (1% overhead).
Market
- Applicable to any RF architecture, communication protocol, modulation scheme.
- Clients : fabless RF chip designers, integrators
- Existing locking techniques for AMS ICs :-Biasing Locking : imprecise and unstable, vulnerable to some attacks ;
- MixLock : induces an 8 to 12% surface and power overload;
- Calibration Locking : not always robust or complex enough.
Development
- PoC based on Nuand’s SDR bladeRF board
- Demonstration with a commercial wifi network
