Public Key Infrastructure (PKI) is an important tool for securing information in the communication. Presently, a PKI framework demonstrates a pattern toward an emerging worldwide PKI which turns out to be more complicated. In this paper, we address the issue of a contact acquiring a message that it missed, from different contacts of the client while keeping up the secrecy of all gatherings required in the networks. Along these lines in this paper, we built up a specific peer-to-peer public key framework model realizing efficient hierarchical identity-based encryption a modification to the proposed by Boneh HIBE. The proposed scheme need not set up a maximum potential recipients set ahead of time, and it has steady size of the general public key, private key, and header of cipher content. We have utilized our proposed key issuing method to distribute private keys of the users to avoid escrow issue problem. We have presented performance analysis with comparison results assuming a PKI network environment.
