Universal Composability Notion for Functional Encryption Schemes
2013
Journal of the Korea Industrial Information Systems Research
We have developed an ideal functionality for security requirement of functional encryption schemes. The functionality is needed when we want to show the security of a functional encryption scheme in universal composable (UC) framework. A functionality was developed to represent ideal respond of a functional encryption scheme against any polynomial time active attacker. We show that UC security notion of functional encryption scheme is as strong as fully secure functional encryption in
