Summary:
We have investigated robust cryptosystems that can be implemented in electronic devices with low computational power, such as IoT devices. The conventional chaos stream cipher with the built-in Rabin cipher in this research has the problem that the randomness of the cipher-text was low and the ciphertext information is larger than the plaintext information. Then, we propose a novel method to improve the randomness by incorporating polynomials and to improve the increase in encrypted information by Jacobi symbols. This paper describes the two proposed systems and their verification results.
