Key and lock device

A key and lock device comprises a key (10) having a first electronic circuitry (14) and a lock (20) having a second electronic circuitry (24). The key and the lock store secret information, some of which is unique for each device. The key and the lock exchange a random number through connectors (15,...

description	A key and lock device comprises a key (10) having a first electronic circuitry (14) and a lock (20) having a second electronic circuitry (24). The key and the lock store secret information, some of which is unique for each device. The key and the lock exchange a random number through connectors (15, 25) and perform a calculation in the respective circuitry based on the random number and secret information. An electrical blocking mechanism (40) is moved to a non-blocking position if a comparison of the calculations in the circuits give an expected result.
