ABSTRACT:
The majority of existing escrowable identity-based key agreement protocols only provide partial forward
secrecy. Such protocols are, arguably, not suitable for many real-word applications, as the latter tends
to require a stronger sense of forward secrecy—perfect forward secrecy. In this paper, we propose an
efficient perfect forward-secure identity-based key agreement protocol in the escrow mode. We prove
the security of our protocol in the random oracle model, assuming the intractability of the Gap Bilinear
Diffie-Hellman (GBDH) problem.
