Identity Authentication Scheme in Opportunistic Network Based on Fuzzy-IBE
Cao Xiao-me · 2014
An identity authentication scheme in opportunistic network was proposed based on Fuzzy-IBE,which can conform to the characteristics of self-organized management,openness and intermittent connectivity in opportunistic networks.The scheme is committed to addressing the security issues such as privacy leaks in the existing social contextbased routing protocols.Because of the intermittent connectivity,the traditional cryptography cannot be applied to the opportunistic networks.So in F-ONIAS,an off-line PKG is used to generate private keys for users.Meanwhile,in identity-based cryptography,identity information may be forged.To avoid such security risks,the biological information is used as a node's identifier.Simulation results show that implementing our security scheme does not induce any negative impact on the average delay,and achieves higher delivery probability and lower routing overhead rate.
