Optimal blowfish algorithm-based technique for data security in cloud

摘要

The cloud computing has elegantly emerged as a unique category of computing which is invariably dependent on sharing computing resources reasonably possessing the local servers or personal devices to successfully address the applications. For the purpose of effectively overcoming the related issues, an optimal blowfish algorithm-based approach is envisioned for the effective encryption and decryption. In the relative step, an innovative signcryption algorithm is elegantly employed for signature authentication. The key manager is entrusted with the task of authenticating the policy related to the file. If the policy precisely corresponds to the file name, then an identical public key is created. If not, a new public key is generated and with the help of public key and private key, the file is encrypted and uploaded into the cloud. The proposed method provides higher security in terms of the data usage for individual persons.
