云计算中基于动态虚拟化电子流密码的安全存储*
Secure Storage Based on Dynamic Virtualization of Electronic Stream Cipher Oriented Cloud Computing*
摘要
Abstract
In order to improve the computing efficiency of user important data security and virtual machine disk integrity verification in cloud computing model, a secure dynamic update storage strategy based on electronic stream cipher in cloud computing is proposed. Firstly, the cloud service provider introduces the concept of virtualization to maintain the virtualization server, storage, and so on to realize the real-time security migration of the virtual machine. At the same time, a model based on the secure electronic stream cipher is introduced. The encryption/decryption uses the ChaCha20 method to maintain the appropriate security for the user sensitive data in the cloud data, to realize data virtualization and dynamic updating in virtual machine disk. Secondly, a new dynamic version of the Merkle B+Hash tree (DMBHT) is proposed. This method does not require random Oracle signature scheme, while uses q-strong Diffie-Hellman (q-SDH) secure short signature, and uses effective bit rate as pseudo delete code (Tornado-z code) on the leaf level of DBHT, which can effectively keep the integrity and authenticity between the virtual machine disk. Finally, simulation results show that the proposed algorithm can achieve fast update and secure modification, and the effectiveness of the proposed algorithm is verified.关键词
