| Abstract: | According to the process of constructing an identity-based encryption scheme based on combined public-key scheme,it proposes the definition of general IBE-CPK scheme,the definition of bilinear map,the definition of complexity assumption,and the notion of security.Based on above all,it suggests a new identity-based encryption scheme.By analyzing the conspiracy attack on CPK,the consequence is that this new scheme defenses this attack. |
