Outline of Final Research Achievements

In this research, we conducted researches on design and implementation of feasible and security proven light-weight cryptographic protocols for low-power devices for authentication and secure communications. This protocol will be used in the devices which do not have enough memory and computational power like PC and servers, thus the existing cryptographic protocols can not be be executed. As results of this research, we designed cryptographic protocols using PUF, which is the difference of actual devices caused by production process, and then prove the security of the protocol from statistic analysis. We also evaluated efficiency in hardware implementation of RFID authentication protocols and show the technical estimations toward practical use.
