In this paper a mechanism for access control at the instance level of a class in object-oriented databases is suggested. The approach is based on the use of pseudo-random functions and sibling intractable functions. Each object-instance in the object-oriented model is associated with access keys that insure secure access to the object and all related objects. The security of the system depends on the difficulty of predicting the output of pseudorandom functions and finding extra collision for the sibling intractable function family. The authorization system supports ownership and granting/revoking of access rights.Read the full paper here: https://link.springer.com/chapter/10.1007/BFb0020519
