In this research, an ACS-based secure data protocol (ACS-based secure data protocol) is introduced for distributed data storage and communication in cloud. The component is constructed using the Owner’s Machine (OM), Data Processing Section (DPS), Cloud Monitoring Server (CMS), Metadata table, Key Management Server (KMS) and Receiver’s Machine (RM). The session key is generated by exchanging the data between the client and server using the mathematical operations, such as interpolation, hashing, Walsh transform and Elliptic curve cryptography. The Triple Data Encryption Algorithm (3DES) is used for performing the activities, like assigning index, uploading and slicing file and encrypting the sliced files. The fuzzy cluster-based mechanism and the angular distance are performed for indexing and retrieval. The metrics, such as E2E delay, time and detection rate are used for evaluating the developed ACS based secure data protocol in the presence of inside attack, password spoofing attack and Denial-of-Service (DoS) attack.
