| Outline of Final Research Achievements |
In this study, we addressed the design and evaluation of lightweight cryptographic schemes that are useful in environments with limited computational resources and cryptographic schemes that provide functions required by applications. For these cryptographic schemes, we proposed schemes that are as secure as conventional schemes and have higher efficiency. We proved that the security of the proposed schemes is guaranteed by the security of their components based on their mathematical definitions, i.e., the security of the proposed schemes is achieved if the components are secure.
