The Key Update Algorithm via HIBE and IKE

摘要：

In this paper we present a new private key update algorithm based on Hierarchical Identity-Based Encryption (HIBE) where a deeryption key can be renewed without having to make changes to its public key. Regarding security, we commence by showing the security of KeyInsulated Encryption (IKE). In addition to this, we propose a three-level encryption model HIBE-IKE by using improved IKE to update the private key in it. The concrete scheme of HIBEIKE with the demonstration of security is also given in the paper.
