InfoBeyond conducted many research on the network security, data security, MAC security, authentication, assurance, security trustworthy, distributed keying algorithms, covert channel, and cross domain security. These algorithms are used for MANETs, sensor, airborne, satellite, mobile computing, and cloud computing.

DataSecurity system protects the data stored in a cloud via encryption or fragment-based data storage, authentication, and Attributed-Based Access Control (ABAC). The system implements high secure data storage, query, and access in a policy-based manner. The system also supports translation of data management policies onto the corresponding user access attributes. These attributes can in turn be validated and enforced for any data access as well as other data operations. For encrypted data, it allows keyword search on encrypted data in cloud servers. Only the user satisfying the predefined policies can fetch and decrypt the data with the corresponding keys. It enables the following security features:

  • Encrypted or fragment-based data storage for a high level of data-at-rest security and privacy
  • Fuzzy searching for users to search the data of his interest from the encrypted data.
  • Preventing the cloud servers, viruses, or insiders to decipher the data content or infer any information.
  • ABAC –enabled data access control. It also achieves a fine-grain flexible access control on the data, having the functions of authentication, authorization, and key distribution for of data owner and users.

There are many benefits for data security and privacy protections:

  • It offers data storage security across different sources. All data are encrypted by the data owner before uploading them into the cloud data servers. For data storage, the data owner is authenticated by the third party (e.g., attribute authority), instead of the cloud data server. The attribute authority enables secure data sharing across various owners.
  • It provides flexible and efficient policy-based data sharing security as the policy is transited to data attribute. The policies are created at the attribute authority by the data owner. They are then transferred into attributes imposed on the data. Only the user satisfying the policy can access the data with corresponding policy.
  • It achieves flexible and efficient secure query. It allows data query and other operations on the encrypted data. In addition, the fuzzy keyword search accommodates users’ typos in the querying keywords.

Preventing data breaches, DataSecurity can be used for data security for hospitals, healthcare, and financial organizations. It can also be used for enterprise cloud database and document management applications if the data are accessed by user policies.
