Privacy-Aware Access Control System in UCSH Private Cloud Using Identity-based Encryption (IBE) and Signature (IBS) Ei Ei Mon Win Win Thant Privacy protection plays a vital role to build up the cloud computing environment. Especially the cloud data storages and data centers must provide and protect individual cloud user’s privacy according to predefined service level agreement (SLA) policies. This system intends to implement secure privacy-aware access control system using Identity based Encryption (IBE) and Identity based Signature (IBS) algorithms, that do not have to generate the keys itself in UCSH Private Cloud. IBE and IBS systems allow any party such as cloud provider, cloud user and trusted third party to generate a public key from a known unique identity value. The corresponding private keys are generated by Private Key Generator (PKG). The proposed system generates public key and private key of cloud service provider (CSP) and cloud users by PKG using IBE and IBS for each user group. When data sent from server to client, first data is encrypted using secret key algorithm. Then key is encrypted using public key of user. Data is signed using the private key of server for the authentication of sender. This system will be implemented as cloud server and cloud client where cloud server stores client data in its data center. Java programming will be used to implement the system. The proposed system provides the private cloud to enhance privacy and security of data. 2019-08-01 https://meral.edu.mm/records/6748
