Research on non-interactive key revocation with identity-based encrption
Hongwei Li · Journal of Computer Applications · 2006
Key revocation in identity-based encryption(IBE),in practice,is unavoidable and also a problem that cannot be bypassed.The non-interactive updating of private keys in IBE was discussed.First certificate-based revocation was introduced that might be useful in IBE.Then some schemes of key evolving were proposed that were the very desired technique in IBE.Finally,identity-based revocation was analyzed,and Hanaoka's solution was introduced that was the best solution,up to now,of non-interactive updating of private keys in IBE.
