摘　　要：Cloud computing has become ubiquitous in our daily lives in recent years.Data are the source of technology that is generated hugely by various sources.Big data is dealing with huge data volumes or complex data.The major concern in big data is security threats.Security concerns create a negative impact on the user on the aspect of trust.In big data still,security threats exist as com-monly known as DDOS(Distributed-Denial-of-Service)attacks,data loss,Inade-quate Data Backups,System Vulnerabilities,and Phishing as well as Social Engineering Attacks.In our work,we have taken the data loss and Inadequate Data Backups issues into consideration.We analyze that RSA(Rivest,Shamir,&Adleman)is the most secure cryptography mechanism.In cloud computing,user authentication is the weaker section to be secured.Generally,the cryptogra-phy mechanism is done in the authentication section only.We implemented our new idea of registration with selected images and pins for processing RSA.By valid authentication approval earned by the proposed mechanism,the user is allowed to use the cloud database,encryption,decryption,etc.To prove the effi-ciency level of our proposed system,a comparison work is conducted between DSSE(Digital Signature Standard Encryption)and EFSSA(Efficient framework for securely sharing afile using asymmetric key distribution management).The experimental work is carried out and the performance evaluation is done using encryption time and decryption time analysis,throughput,and processing time.On this observation,the security level attained by ERSA is far better in compar-ison to DSSE and EFSSA with the maximum throughput attained by the proposed E-RSA being 500 Mb/Min and encryption time of 3.2 s,thus ensuring the user trust in using the cloud environment.
