The emergence of computer and computer networks made the people life very simple on one touch. But, is the network really secured? Do our transactions are done in a trusted manner? These thoughts lead us to network security. For the past few decade, network security places vital role in ensuring safe and secured communication over the Internet. In our day to day life, most of the communication are carried out to ensure safe account transactions. Thus security in banking domain should be highly secured and user-friendly to have the smooth communication. An effort has been taken in this paper to provide a better security model by adapting ABE and AES than existing security systems. Every user registers and gets a username and password for authentication. We deploy four admin for the overall control of data access. The proposed model provides great security to various access policies based on different scenarios. Every admin is provided with user-id, password, challenge-key and its corresponding challenge response key, ABE key and MAC and IP Address captured in Cloud. Every admin is assigned with certain access privilege & ABE key is assigned. Servers generate a new key and divided with the available numbers of administrators. This key is sent as Email alert to every administrator. If any query requested by the user beyond the permitted privilege of the corresponding administrator then that admin will the permission from rest of the administrators by getting everyone's Joint Threshold key and finally concatenated and verified by the server then access permission is provided. © IAEME Publication.
