| Popis: | In this paper the ID-based signcryption scheme of Li, Xin, and Hu is extended to a compartmented scheme. If an organization is partitioned into different compartments, this scheme allows any member of a specific compartment to participate in the unsigncryption; moreover, each member of a compartment has information unique to that individual. This construction is the first (to the authors' knowledge) to combine identity-based encryption, Shamir's threshold scheme, and signcryption into an implementable compartmented sharing scheme. We extend an ID based signcryption scheme to a compartmented scheme.Our scheme allows any member of a compartment to participate in unsigncryption.The security of this scheme is just as strong as the original.Much of the setup work is naturally parallelizable.It is applicable to modern situations and lends itself easily to implementation. |
