SYSTEM FOR SAFETY VERIFICATION OF CRYPTOGRAPHIC ALGORITHMS BASED ON SIDE-CHANNEL ANALYSIS AND METHOD FOR CONTROLLING THEREOF

摘要

The present invention relates to a system for verifying the safety of the encryption algorithm based on a result of analyzing subchannel information according to an encryption algorithm, and performs communication connection with a target device and based on an operation signal received from the target device an operation signal detection unit for detecting the start and end of driving of the encryption algorithm; a trigger signal generation unit for controlling generation of a trigger signal for obtaining sub-channel information from the target device based on the detected operation signal; a sub-channel information collecting unit that collects sub-channel information from the target device while the encryption algorithm is running, and analyzing the collected sub-channel information to estimate an encryption key of an encryption algorithm driven in the target device , characterized in that it comprises a side-channel information analysis unit for verifying the safety of the encryption algorithm based on the estimated encryption key.
