摘　　要：现阶段分布式网络出现可靠性低、安全性低等问题,构建相应的存储运输保障机制具有积极的意义。研究提出CP-ABE数据加密方案,该方案以Ethereum网络作为分布式网络系统架构,将IPFS作为数据存储网络,通过密文半解密算法和密钥转换算法改进CP-ABE算法实现第三方加密。研究结果表明,相较于其他数据加密方案,CP-ABE数据加密方案在属性组数为90时,加密时间和解密时间分别最短和最长,相应数值分别为1.68s和2.62s,且CP-ABE数据加密方案的解密时间不会随着请求者数量的增加而增加。研究所提出的CP-ABE数据加密方案能够大幅度提升分布式存储运输的数据安全。At present,the distributed network has the problems of low reliability and low security.It is of positive significance to build the corresponding storage and transportation guarantee mechanism.A CP-ABE data encryption scheme is proposed.The scheme takes Ethereum network as the distributed network system architecture and IPFS as the data storage network.The CP-ABE algorithm is improved through ciphertext semi decryption algorithm and key conversion algorithm to realize third-party encryption.The results show that compared with other data encryption schemes,when the number of attribute groups is 90,the encryption time and decryption time of CP-ABE data encryption scheme are the shortest and the longest respectively,and the corresponding values are 1.68s and 2.62s respectively,and the decryption time of CP-ABE data encryption scheme will not increase with the increase of the number of requestors.The proposed CP-ABE data encryption scheme can greatly improve the data security of distributed storage and transportation.
