摘要
阐述了分布式网络中用加密方法保护交换数据的必要性,结合Ganglia网络,提出了一个适合于分布式网络的基于属性的加密方案.与其他方案比较表明,本方案定长的密文、高效的加解密流程以及良好的灵活性等特点在实际部署引用中具有实用价值。
In this paper,the necessity of protecting the data exchanged between nodes was elaborated and a distributed attributed-based encryption scheme was proposed based on Ganglia Network.The advantages of this scheme was also discussed and compared with other existing schemes.Finally,the value of use in practice of this scheme,such as constant ciphertext length,high effiencies in encryption and decryption,and good flexibility was summarized.
