Design And Implementation Of Cloud Storage Security System

With the growth of cloud storage technology continues to mature and the mass ofinformation, the cloud storage system has been more widely used, it also brings newstorage security issues, and the traditional storage security measures have been difficult tomeet current safety requirements.The security mechanism for cloud storage system was designed and implemented,using the attribute-based encryption access control mechanism to achieve efficient andscalable access control, solving the low efficiency access control problem brought bymassive users of cloud storage system and large volumes of data; using symmetricencryption to ensure the confidentiality of the data, using the evidence to ensure dataintegrity, serial writing features and the latest reading features. Using evidence, so that theauditor can detect the behavior of the cloud storage system is reliable, provides a reliablesecurity system for users and cloud storage, so that users are more willing to adopt thecloud storage system, helping the development of the cloud storage system.The test results show that the proposed security mechanism makes cloud storagesystem read performance dropped by about20%, the write performance dropped by about16%, and speeds of auditing evidence up to25,000per second, attribute encryptionmechanism achieves efficient scalable access control, while protecting the security ofcloud storage system to maintain the high performance of the cloud storage system.
