A mutual authentication method using a mediation module (300) and a system therefor are provided. The method includes: storing a first partial private key obtained by dividing a first private key of a device; storing a second partial private key obtained by dividing a second private key of a host device; receiving unique identifiers (IDs) and random numbers for the device (200) and the host device (100) from the device and determining whether the unique IDs are valid; and generating a first signature value by using the first partial private key and a second signature value by using the second partial private key if the unique IDs are valid, and transmitting the generated first and second signature values to the device
