Fast and Secure Data Accessing by Using DNA Computing for the Cloud Environment

In a cloud environment, traditional approaches are used to encrypt any data by using 0 and 1 that increase data security issues because of the presence of numerous malicious users and hackers over the internet. Deoxyribonucleic Acid (DNA) computing can be one of the best solutions to improve data security in which data are encrypted using the DNA bases: Thymine (T), Guanine (G), Cytosine (C) and Adenine (A). Along with data security, access control is another major issue of a cloud environment as the searching time of the owner of any data, the system overheard and the accessing time of a file or data are high during data access. A novel DNA computing based secure and fast Access Control Model (ACM) is proposed in this article to solve all these major problems. In the proposed scheme, the Cloud Service Provider (CSP) keeps a table or list for fast data accessing. Here, a 1024-bit DNA computing based random key is generated by using the user's secret information, and the same key is utilized for data encryption. Theoretical analysis along with many experimental results prove the efficiency and effectiveness of the proposed access control model over some well-known existing models.
