         48 . An operation method of a portable personal device having facilities for storing and playing digital contents by control from a computer through a serial or parallel cable, the method comprising the steps of: 
 (a) receiving a security key registration request command from the computer through a serial or parallel cable for registering a security key in the portable personal device;    (b) sending information indicating that the portable personal device is ready to register the security key, to the computer through a serial or parallel cable, when the portable personal device is ready to register the security key;    (c) receiving the security key sent by the computer through a serial or parallel cable; and    (d) sending information indicating whether or not the security key is normally received in the step (c), to the computer through a serial or parallel cable, wherein the structure of the transmission data which is received or sent in the steps (a) through (d) includes a start separator character for indicating a start of transmission data, information on length of the transmission data, an intermediate separator character for indicating a start of a command code or state information, the command code or state information, and an end separator character for indicating an end of transmission data.    
     
     
         49 . The operation method of  claim 48 , wherein the security key is a proper identifier of the portable personal device.  
     
     
         50 . The operation method of  claim 48 , wherein the security key is a proper identifier of a manufacturer of the portable personal device.  
     
     
         51 . The operation method of  claim 48 , wherein byte length of the security key is 128 bytes.  
     
     
         52 . The operation method of  claim 48 , wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.  
     
     
         53 - 84 . (canceled).  
     
     
         85 . An operation method of a portable personal device having facilities for storing and playing digital contents by control from a computer through a serial or parallel cable, the method comprising the steps of: 
 (a) receiving in the portable personal device a meta data request command from the computer through a serial or parallel cable for requesting meta data that is information required for reproducing digital contents in which a security function is set, downloading a file from the computer, or uploading a file to the computer;    (b) when the meta data request command is received in the step (a), returning total byte length information of meta data to be sent to the computer through a serial or parallel cable; and    (c) sending meta data, including a type of an encryption algorithm, a type of a hash algorithm, and a version of a random number generator, used by the portable personal device, to the computer through a serial or parallel cable.    
     
     
         86 . The operation method of  claim 85 , wherein sending and receiving data between the computer and the portable personal device through a serial or parallel cable in each step is mediated by a docking station.
