Cloud computing provides reliable and efficient services for sharing data among cloud users at low maintenance cost. Providing privacy, confidentiality, and integrity of data among users in untrusted network environment is a major issue in cloud computing systems, especially where members frequently change their groups. In this paper, we proposed secure file distribution system for untrusted network environment. Our proposed scheme allows users anonymously share their files among members by

The scheme also provides low storage overheads and computational cost independent of the number of revoked users, and support handheld devices with little computational power, low memory and storage capacity. We subjected our scheme to rigorous proofs and security analysis through stimulation and compare the results with other existing protocols thus, MONA and ODBE by considering computational cost for file generation and access.
