In today’s era, cloud computing has become the more promising business concept which impacted almost every section of our lives and business. Cloud computing for sure has grown rapidly to become one of the major areas of research. As it provides an on demand access to a shared pool of resources and makes easier for the organizations to use their data at any place and at anytime without considering hardware devices along them but cloud security is still the most crucial and considerable issue in each organization. So there is need for some secure authentication so that data on clouds remain safe and secure. In this context passwords are the basic form of authentication. so there is need of some mechanism which provides password security. Weak and poor passwords management leads to breach in cloud data. Passwords to gain access to secret data should be so as strong to prevent dictionary attacks and brute force attacks. In our proposed system a mechanism is presented to secure the data on cloud using combination of some algorithms viz: PBKDF2, Argon 2, AEs-256 and IDA. In this paper we proposed a method to generate the most secured cryptographic keys using the blend of two key derivation functions PBKDF2 and Argon 2. In our proposed model there would be no need to store and send key for encryption and decryption. Advanced Encryption Standard (AES) is used for encryption for encryption. Information Dispersal algorithm is used to prevent data breaching situations on clouds in financial institutions and provide better confidentiality, availability and integrity of data.
