| Abstract: | The loss of on-board domain and appearance of multi-tenant context bring some new problems and challenges to access control.In this paper,these problems are listed and the reasons are analyzed first.And then,aiming at these problems,the corresponding solutions and techniques are introduced in terms of identity provision,authentication,authorization,identity federation and single sign-on.Next,latest works about access control of cloud computing are reviewed in terms of access control models,attribute based access control of cipher text,and access control of outsourcing data.At last,the trend of study on access control of cloud computing is analyzed and predicted. |
