In recent times hackers have been engaging in different string concept on login fields and phishing in order to intrude cloud accounts. This research is proposed to carry out effective security mechanisms on loopholes in cloud data storage. We intend to engage the use of the Advanced Encryption Standard (AES), security Algorithms like Secure Hash Algorithm 1 & 3 (SHA1, SHA 3) and Message-Digest Algorithm (MDS) and the Standard Authentication Scheme (AS) as sure guide against phishing which when implemented can provide various login stages and codes like OTP (One Time Password) to mitigate attacks. With the application of these methods towards securing cloud computing data there will be less intrusion in accounts and loss of files. Keywords: Brute-force, Cracking, Hacking, Advanced Encryption Standard, Authentication Scheme, AES, ES, Security 1. INTRODUCTION Cloud computing is a developing registering worldview that can conceivably offer various imperative points of interest. One of the principal preferences is payment based on service usage evaluation model, where clients pay just as per their utilization of the service. It served as a web based registering. As stated by NIST (United State National Institute of Standard and Technology), cloud computing gives organizational potential benefit which included improved of business outcomes. It is powerfully conveys everything as a service over the web in view of client interest, for example, system, working framework, stockpiling, equipment, programming and assets.
