Key and lock device

The present invention relates to a key and shutter mechanism having a key and a lock arrangement and comprising a first structure having a first electronic processor; a first memory connected to the first electronic processor; and a first connector connected to the first electronic processor. The key converter structure further comprises a second structure having a second electronic processor; a second memory connected to the second electronic processor; and a key connected to the second electronic processor for the locked key, the key for securing the information between the lock and the second connector of the first connector is mechanically cooperative. Auxiliary and shunt devices also provide energy source; mechanikusreteszelőszerkezetet; and one, the unlocked key in the lock contains an electronic locking mechanism for preventing the lock from operating. The first memory is PKID; PLID public ID and SKID; SLID secretly stored for secret storage; the second memory is PKID_1 for eligible first structures; PLID_1 public ID and SKID_1; SLID_1 is configured for secret ID storage; its first electronic processor is PKID; By PLID public identifier, the second electronic proxy is self-identifying; and replacing the first and second electronic processor RND random numbers and the SKID; Using at least part of the SLID secret ID and at least a portion of the RND random number, CODE_KEY, CODE_LOCKcodes are calculated computationally; and the electric locking device is not locked in position if the coders calculated by the first and second electronic processors are the same. The present invention also relates to a key structure corresponding to the above first or second structure. ŕ
