| Research Abstract |
Our research goal is to establish theories on security analysis of public key cryptosystems. We employ the lattice theory for its analysis. We succeeded in obtaining more accurate conditions for solving some problems related to public key cryptosystems such as RSA scheme and knapsack scheme. Then, we succeeded in providing more accurate security analysis for such schemes. These results enable us to use cryptographic technologies more securely and adequately.
