基于PKI和IBC的双向匿名异构签密方案
Two-way and anonymous heterogeneous signcryption scheme between PKI and IBC
摘要
Abstract
Exiting heterogeneous signcryption schemes which were between public key infrastructure (PKI) and identi-ty-based cryptosystem (IBC) have some limitations. A new heterogeneous signcryption scheme between PKI and IBC was proposed. In the random oracle mode, the scheme ensured confidentiality and unforgeability on the basis of the as-sumption of computational Diffie-Hellman problem (CDHP), q-Diffie-Hellman inversion problem (q-DHIP) and bilinear Diffie-Hellman problem (BDHP). Simultaneously, the proposed scheme guaranteed unconnectedness and anonymity of the ciphertext. Compared with other heterogeneous schemes, the scheme achieved two-way signcryption, and it generated pa-rameters without restrict, which was suitable for actual situations. Simulation tests show that proposed scheme is feasible.关键词
