Abstract(in English) | We propose a public key cryptosysmtem using the traveling salesman problem that is a NP complete probrem. A cycle corresponds to a plaintext and the total distance correspond to the ciphertext. We use Fibonacci numbers as the distance between the cities. In case of a plaintext and the ciphertext show one to one correspondence, by using the backtracking method, we can decrypt the ciphertext uniquely. We examine the security of this cryptosystem against LLL algorithm numerically. |
