摘要
为了提高大数据加密速度,保证人力资源大数据安全,研究一种基于区块链技术的人力资源大数据加密方法。利用区块链技术中的哈希函数计算人力资源数据的活跃程度,通过与阈值对比消除冗余数据;利用区块链技术将大数据划分为若干数据区块,实现数据分化;利用RSA算法生成密钥,通过密钥对经过置乱处理的数据块实施加密,完成基于区块链技术的人力资源大数据加密。实验结果表明:利用所研究方法对大数据样本进行加密,密文复杂程度在90%以上,且所花费的加密时间均小于5 s,方法加密速度较快。
In order to improve the speed of big data encryption and ensure the security of human resources big data,a human resources big data encryption method based on blockchain technology is studied.It uses the hash function in blockchain technology to calculate the activity of human resource data,and eliminates redundant data by comparing with the threshold,uses blockchain technology to divide big data into several data blocks to realize data differentiation.RSA algorithm is used to generate the key,which encrypts the scrambled data block,and completes the human resources big data encryption based on blockchain technology.The experimental results show that the complexity of the ciphertext is more than 90%and the encryption time is less than 5 s,and the encryption speed of the method is faster.
