| 摘要: |
| 利用数据划分思想和多线程技术,提出一种加解密数据库数据的方法并用实验来检验方法的有效性。该方法使用3-DES密码算法,参考资源调度策略与划分机制,在多核计算机系统上对数据库中待加解密的数据进行划分,并利用多线程并行技术对数据进行加解密处理。实验结果表明,多核多线程并行方法能够显著地加快数据库数据加解密速度。 |

| Abstract: |
| Based on data partitioning idea and multi-threading technology, a database encryption and decryption method is proposed and its effectiveness is verified by experiments.The data stored in database on a multi-core computer are firstly partitioned by applying resource scheduling strategy and partitioning mechanism.Then the data are encrypted/decrypted by parallel multiple threads and 3-DES cipher algorithm.The experimental results show that the presented method can accelerate significantly the database encryption and decryption operations by multi-core multi-threading techniques. |
