Combined Public Key Management Scheme Based on IBE
Fei Ma · Computer and Digital Engineering · 2012
Based on the special nature of bilinear pairings on elliptic curves,this paper proposed a new combined public key management scheme based on identity-based encryption.This scheme produces user public key according to the method of CPK and simplify the the map from ID to the group of points on an elliptic curve.This scheme solution collusin attack and problem of distributing the user's private keys.
