The cylinder plug  111  includes a data communication unit  105  which is electrically contacted with a terminal unit  113  provided in the key head  201  of the electronic key  103 ; and a data processing unit  109  that determines authentication by comparing ID information of the electronic key  103  transmitted by the data communication unit  105  with a pre-stored ID database. 
     First, a structure of the electronic locking device  100  will be described as an example. 
     The electronic locking device  100  includes the cylinder housing  101  and the cylinder plug  111 . 
     The cylinder housing  101  forms the appearance, and the cylinder housing  101  has, for example, a hollow cylindrical shape, and a thread is formed on the outer circumferential surface of the cylinder housing  101  and may be screw-coupled with a coupling hole formed in a door or the like. 
     The cylinder plug  111  is located inside the cylinder housing  101  and rotatably installed in place, the cylinder plug  111  is locked or unlocked to the cylinder housing  101 , and a latch bolt  203  is coupled with the cylinder plug  111  and rotated together according to the rotation of the cylinder plug  111 . 
     Meanwhile, in such a cylinder plug  111 , the data communication unit  105  which is detachably inserted with the key head  201  of the electronic key  103  and electrically contacted with the terminal unit  113  of the key head  201  is provided and a lock head  211  in which a second supporter  209  corresponding to a first supporter  207  formed in the key head  201  to fix the electronic key  103  is provided. 
     That is, in the lock head  211  provided in the cylinder plug  111 , a key insertion hole  205  to which the key head  201  of the electronic key  103  is detachably inserted is formed, and a plurality of data communication units  105  is provided on the bottom (that is, an opposite surface in an opened direction) of the key insertion hole  205  and contacted with the terminal unit  113  provided in the key head  201  when the key head  201  of the electronic key  103  is inserted to the key insertion hole  205 . Power and the ID information from the electronic key  103  are transmitted to the cylinder plug  111 . 
     Meanwhile, in the lock head  211 , the second supporter  209  is formed and corresponds to the first supporter  207  formed in the key head  201  of the electronic key  103  to fixedly support the key head  201  inserted to the key insertion hole  205 . 
     When describing an example for the structure of the first supporter  207  and the second supporter  209  in detail, the first supporter  207  is formed on the outer circumferential surface of the key head  201  as a concavely recessed groove, and the second supporter  209  is provided on a circumferential surface of the key insertion hole  205  to which the key head  201  is inserted, corresponds to the first supporter  207 , and may be formed as an elastically supported protrusion. 
     That is, the second supporter  209  may have a structure in which a head portion  301  exposed to the outside from the circumferential surface of the key insertion hole  205  is rounded and an elastic body  305  is coupled to the outer circumferential side of a guide shaft  303  integrally extended from the head  301 . 
     Accordingly, when the key head  201  is inserted to the key insertion hole  205 , the head  301  of the second supporter  209  is pressed and jumped out by the elastic restoring force of the elastic body  305  to press and support the first supporter  207  of the key head  201 , thereby preventing the electronic key  103  from being easily detached from the cylinder plug  111 . 
     The objects of forming the first supporter  207  and the second supporter  209  described above may also be interchanged, and that is, the first supporter  207  may be formed on the outer circumferential surface of the key head  201  as an elastically supported protrusion, and the second supporter  209  may be provided on a circumferential surface of the key insertion hole  205  to which the key head  201  is inserted to correspond to the first supporter  207  as a concavely recessed groove. 
     Meanwhile, the cylinder plug  111  includes the data processing unit  109  which performs a function of determining authentication by comparing ID information of the electronic key  103  transmitted by the data communication unit  105  with the pre-stored ID database, a function of storing log information L about the authentication, a function of transmitting the stored log information L to a memory unit  107  of the electronic key  103  via the data communication unit  105 , and the like. 
     In the data processing unit  109 , the ID database is pre-stored, and the data processing unit  109  determines authentication by comparing the ID information of the electronic key  103  transmitted by the data communication unit  105  with the ID database. 
     Only when the ID information of the electronic key  103  is authenticated, a process for the subsequent unlocking operation of the cylinder plug  111  proceeds. 
     Further, the data processing unit  109  stores log information L indicating whether the electronic key  103  is authenticated, and the log information L includes, for example, log information about whether the electronic key  103  is authenticated or not, log information about an open/close time by the authenticated electronic key  103 , and log information about registration/change of a master electronic key. 
     Meanwhile, the data processing unit  109  transmits the log information L to the memory unit  107  of the electronic key  103  via the data communication unit  105 , and in this case, the data processing unit  109  transmits the log information L to the memory unit  107  of the electronic key  103  and then deletes or leaves the stored log information L according to a predetermined condition. 
     That is, after the log information L is transmitted from the data processing unit  109  to the memory unit  107  of the electronic key  103 , the log information L may be left in the data processing unit  109  or deleted and removed, which is determined by a predetermined condition in relation to whether the log information L is deleted.
