Abstract:
Security protocols may be provable secure when used alone, but these protocols lose their security under composition operation. Universal Composition framework (UC) is a tool for analyzing security protocols under composition. UC framework guarantees that the cryptographic protocols keep their security under this composition operation. In this paper we state a modeling for key-evolving signature protocol within the UC framework as a case study. To do this, the ideal functionality is proposed for key-evolving signature scheme that keeps the security requirements of this scheme. Finally, we show that UC definition of security is equivalent to definition of security which is termed here as EU-CMA security
