针对Hadoop平台静态存储加密方案的加密算法单一、密钥管理复杂、加解密性能低,不能高效保护Hadoop数据安全的问题,提出了一套基于商用密码算法的 Hadoop 高性能加密与密钥管理方案。首先,提出基于国产商密算法的 Hadoop 平台三层密钥管理体系,优化二级密钥的组织结构;其次,提出异步流水模式的高并发加解密方法,替代 Hadoop 原有的串行加解密流程,并通过密文排序确保多加密线程的密文同步。实验结果表明,所提方案的密钥存取效率、文件读写速度快于原有Hadoop方案,所提方法可有效提升Hadoop平台密钥存取与加解密速度。
To address the problem that as preventing data leakage on Hadoop platform
the existing encryption schemes suffer from several problems (e.g.
single encryption algorithm
complicated key management
low encryption performance) and they cannot protect data stored in Hadoop effectively
a high-performance encryption and key management scheme for Hadoop was proposed.Firstly
a three-level key management system was extended with the domestic commercial cipher algorithm.Then
a new data structure for encryption zone key to reduce time consumption was designed.Finally
the computing process of data stream in parallel was scheduled.The experimental results show that compared with the existing Hadoop schemes
the proposed scheme can improve the efficiency of key management
and can speed up file encryption.
