Cloud computing is one of the space-ground integration information network applications.Users can access data and retrieve service easily and quickly in cloud.The confidentiality and integrity of the data cloud have a direct correspondence to data security of the space-ground integration information network.Thus the data in cloud is transferred with encrypted form to protect the information.As an important technology of cloud security,access control should take account of multi-factor and cipher text to satisfy the complex requirement for cloud data protection.Based on this,a proxy re-encryption based multi-factor access control (PRE-MFAC) scheme was proposed.Firstly,the aims and assumptions of PRE-MFAC were given.Secondly,the system model and algorithm was defined.Finally,the security and properties of PRE-MFAC were analyzed.The proposed scheme has combined the PRE and multi-factor access control together and realized the multi-factor permission management of cipher text in cloud.Meanwhile,it can make the best possible use of cloud in computing and storing,then reduce the difficulty of personal user in cryptographic computing and key managing. |
