摘要：Now a day's cloud computing is very popular in large and small scale organization as it will stored large amount of data and provide low cost service. Hence it was create daily new challenges to provide secure authorization, integrity and access control. Some approaches are ensuring about security but there are also some lack in these approaches and issues due to collusion attack, heavy computation. To resolve this issue we proposed a scheme its threshold cryptography in which data owner can divide users in group and provide single key with the using key each user in group can access the data. In these studies, we use capability list to control the access. In this scheme not only provide data security but alsoprovide reduce number of keys
