WebDec 20, 2000 · It is proved that the proposed new signcryption scheme is existentially unforgeable, in the random oracle model, subject to the assumption that factoring an RSA modulus N = pq (with p and q prime) is hard even when given the additional pair (g; S). Signcryption is a public-key cryptographic primitive introduced by Zheng, which achieves … WebDefining the goal for signcryption. The security goal of signcryption can be identified in a very natural way: due to the nature of public-key cryptography, the security depends on which user gets compromised. Furthermore, in a public … birth double clock tattoo designs
