Enhancement of Public Cloud, Application Security, Using Bcrypt Algorithm

Authors(2) :-Shri Ranjani. N, Ravikumar. B

The emergence of internet has lead to the booming of internet based applications and services. One such domain which has developed at an exponential rate is cloud computing. Nowadays, most of the applications run on cloud environments. Even a highly critical application such as banking applications use cloud backends for storing data. But, such applications, which has a very high confidential data do not run on private clouds. The use of private cloud computing may not be possible for all applications as it requires more cost for creating a cloud environment and maintaining it. We can have our application in public clouds if the data stored are not highly confidential. This is where application level security in cloud comes into play. In this paper, we deal about the enhancement of application level security in any application where data resides in a public cloud. Here, we use a highly complicated cryptographic algorithm, Bcrypt, which is used to store passwords
