Linx Technologies introduces CipherLinx, a security for Remote Keyless Entry (RKE) and remote control devices. The secure, encrypted technology offers an advanced level of security and features. CipherLinx is based on a core algorithm called Skipjack, developed by the United States National Security Agency (NSA). One of its key features is that the technology will never send or accept the same packet twice. This alone makes it more secure than "rolling code" type devices, which can repeat packets multiple times. Additionally, CipherLinx changes codes with every packet sent, not just every button pressed.
