In cryptography, the interlock protocol, as described by Ron Rivest and Adi Shamir, is a protocol designed to frustrate eavesdropper attack against two parties that use an anonymous key exchange protocol to secure their conversation. A further paper proposed using it as an authentication protocol, which was subsequently broken.
CBIs are mostly implemented in two parts; a section that implements the safety and failsafe requirements, and a second section that implements "non-vital" controls and indications.
In France, the interlock programme has included a mandatory addiction consultation (without any ongoing monitoring during the program and no data analysis). In 2018, an alcohol interlock in repeat offences became compulsory and a trial was extended to the entire country. 1,500 ignition interlock devices were installed from 2018-2020 of a total ...
