Distributed Cipher Hashing Cryptographic Technique For Secure Data Storage In Cloud Computing Using XOR-MECC

Abstract

The user is enabled by means of Cloud Computing (CC) to store and access the data as of anywhere. To secure the data amassed on the Cloud Server (CS), CC security encompasses a collection of policies and technologies. Most existing methods bring about a lower-Security Level (SL), the higher computation time for encryption together with decryption, and also Memory Usage (MU) issues, et cetera. Here, to resolve such issues in the existent methods, an effectual modified cryptographic is proposed in favor of the secured Data Storage (DS) in CC. Firstly, secure authentication is done via the Alder32 hash algorithm. The user is authenticated via registration, login, together with verification. Subsequently, the authenticated user commences uploading the file. Prior to uploading, the inputted file is bifurcated into sub-files counting on the size, and the features are extracted as of the split file and distributed CS. Next, the Brownian Motion-based BAT algorithm (BM-BAT) selects the appropriate distributed CS. Then, the Modified   Cryptographic (XOR-MECC) uploads the files securely into the CS. The experimentation's outcomes state that the proposed work attains better performance when weighed against the prevailing works.
