Management of Symmetric Cryptographic Keys in cloud based environment

Although, cloud computing provides innumerable benefits to its customers but it fails to solve information security concerns especially in public cloud. Symmetric Cryptographic Key is sensitive data and it is required to be stored at cloud platform to solve several problems of encrypted data such as searching/manipulation on encrypted data. This paper presents a technique that will manage symmetric cryptographic keys on cloud-based environment. Proposed technique is based on secret splitting technique enhanced Shamir's algorithm. Proposed technique is implemented in OpenStack private cloud environment for performance analysis and it is found out that the technique works efficiently. In addition, it is fulfilling the best practices metrics, given by National Institute of Standard and Technology.
