Abstract
A validation server using HSM, which reduces required process time from receiving a validation request to responding with a validation result, and comprises a first software cryptographic moduleand a second software cryptographic moduleon a validation serverwhose HSM is coupled with an I/F part. According to the validation server, load states of HSM, the first software cryptographic moduleand the second software cryptographic moduleare monitored by a cryptographic module monitor unit, and when cryptographic calculations in a validation process of certificates are conducted, the cryptographic calculations are executed by using the least loaded cryptographic module selected at a cryptographic module selector unit
