Abstract:
This paper proposes a new multi-bank E-cash scheme based on bilinear pairings, by using proxy-signcryption technology to realize multi-bank proxy authorization and the E-cash generation. Theoretical analysis results show that using the bilinear pairings can design a safer, simpler and highly effective multi-bank E-cash scheme, because with signcryption technology, it makes the agreement simpler and highly effective, its computation and communication costs are relatively lower, so that the scheme is more suitable for the safe mobile termination and all kinds of embedded equipments.
