Dalam kertas mani penyulitan berasaskan identiti (IBE), Boneh dan Franklin [6] menyebut perubahan menarik daripada skim IBE kepada skim tandatangan, yang diperhatikan oleh Moni Naor. Dalam kertas kerja ini, kami memberikan rawatan keselamatan formal untuk perubahan ini dan menemui beberapa implikasi dan pemisahan antara tanggapan keselamatan IBE dan tandatangan yang diubah. Sebagai contoh, kami menunjukkan untuk transformasi yang berjaya, kesehalaan IBE adalah syarat penting. Selain itu, kami memberikan syarat yang mencukupi dan perlu untuk menukar skim IBE selamat secara semantik kepada skim tandatangan yang tidak boleh dipalsukan. Keputusan kami membantu mewujudkan strategi pada reka bentuk dan bukti keselamatan automatik bagi skim tandatangan daripada (mungkin lemah) skim IBE. Kami juga menunjukkan beberapa hasil pemisahan yang sangat menyokong bahawa kesehalaan, bukannya keselamatan semantik, IBE menangkap syarat penting untuk mencapai tandatangan selamat.

Abstract: In a seminal paper of identity based encryption (IBE), Boneh and Franklin [6] mentioned an interesting transform from an IBE scheme to a signature scheme, which was observed by Moni Naor. In this paper, we give formal security treatments for this transform and discover several implications and separations among security notions of IBE and transformed signature. For example, we show for such a successful transform, one-wayness of IBE is an essential condition. Additionally, we give a sufficient and necessary condition for converting a semantically secure IBE scheme into an existentially unforgeable signature scheme. Our results help establish strategies on design and automatic security proof of signature schemes from (possibly weak) IBE schemes. We also show some separation results which strongly support that one-wayness, rather than semantic security, of IBE captures an essential condition to achieve secure signature.
