<p>PROBLEM TO BE SOLVED: To provide a securing device of a recording medium drive for ciphering data from an interface port of a main board of a computer and inputting them to an interface port of a recording medium drive, and deciphering the data from the interface port of the recording medium drive and inputting them to the interface port of a main board. SOLUTION: The securing device includes a ciphering part, a deciphering part, and memory. The ciphering part ciphers the data from the interface port of the main board with a logic circuit and inputs them to the interface port of the recording medium drive. The deciphering part deciphers the data from the interface port of the recording medium drive by hardware of a logic circuit and inputs them to the interface port of the main board. The memory provides ciphering data inputted from a user to the ciphering part and the deciphering part.</p> |
