Abstract

Cloud computing is the trendy topic all over the world. With increase in popularity of cloud computing, more and more enterprises will outsource their sensitive data for sharing in a cloud. Cloud computing allows the users to share the data among the members of cloud. One of the issue in cloud computing is data security. Here the problem is whenever a user is revoked from cloud the data owners will send re-encryption command to cloud in order to re-encrypt the data so that the data is prevented from revoked users. In this paper, we propose a time-based re-encryption scheme using blowfish algorithm. This scheme allows the cloud to automatically re-encrypt the data based on the internal clock, users can access data within given time period, after time period get over user cannot access data, this scheme also prevents the revoked users from decrypting the data using their old decryption keys.
