摘　　要：针对学前儿童心理健康测试仪数据传输存在泄露风险,导致数据传输安全性降低的问题,提出基于Logistic混沌序列+AES加密的数据加密传输算法。此算法通过Logistic混沌序列进行二值序列提取,然后结合AES加密进行数据加密、密钥同步和密钥管理,以此实现学前儿童心理测试仪的数据加密传输。测试结果表明,在传输数据大小为2 MB、20 MB、100 MB、200 MB的测试结果中,提出的Logistic混沌序列+AES加密算法的加密时间分别为0.24 ms、1.73 ms、7.75 ms、18.42 ms,均低于单一的混沌序列和AES加密算法。且相较于传统的AES数据加密算法,本算法的加密速度分别低了15.57 ms、192.77 ms、1443.58 ms、2 600.18 ms。且本算法的明密文敏感性和平衡度均优于传统的Logistic混沌序列和Tent混沌序列。由此可知,本算法对测试仪不同数据传输类型的所用加密时间更短,加密速度更快,数据传输加密、解密敏感度较高,说明算法的安全性能更高,可有效避免数据传输的泄露和盗取风险。In view of the risk of data transmission and data transmission reduces the security of data transmission, a data encryption transmission algorithm based on Logistic chaotic sequence + AES encryption is proposed. This algorithm performs binary sequence extraction through Logistic chaotic sequence, and then performs data encryption, key synchronization and key management combined with AES encryption, so as to realize the data encryption transmission of preschool children psychological tester. The test results show that the encryption time of the proposed 2 M S is 204 M s, in the 2 MB, 100 MB and 200 MB, respectively 1.73 ms, 7.75 ms, 18.42 ms, both lower than a single chaotic sequence and an AES encryption algorithm. Compared with the traditional AES data encryption algorithm, the encryption speed of this algorithm is lower than 15.57 ms, 192.77 ms, 1 443.58 ms, 2 600.18 ms. And the text sensitivity and balance of this algorithm are both due to the traditional Logistic chaotic sequence and the Tent chaotic sequence. Therefore, the algorithm uses shorter encryption time for different data transmission types, faster encryption speed, and the data transmission encryption and decryption sensitivity is higher, indicating that the security performance of the algorithm is higher, which can effectively avoid the leakage and theft risk of data transmission.
