英文摘要 | A multi-level data security program based on quantum key is proposed in this paper aiming to improve the security of documents in computers. Since the generation of quantum keys is secure theoretically, incorporating time phase coded quantum key distribution networks into classical networks in this program provides a practical way to achieve dual-network integration. Moreover, a quantum key utilization strategy of three quantum keys, including onetime- pad, 16-byte key AES-128 algorithm and SM4 algorithm, are employed according to the importance level of the documents based on low quantum key bit rates of commercial optical fibers. Experimental results demonstrate that dual networks can operate steadily and the encryption/decryption for a 10 MB document of the proposed multi-level security device costs less than 10 s. Hence, a high level of protection for data security is realized through the proposed multi-level data security program. |
