An ID-Based Signcryption Scheme with Compartmented Secret Sharing for Unsigncryption
نویسندگان
چکیده
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 identitybased encryption, Shamir’s threshold scheme, and signcryption into an implementable compartmented sharing scheme.

ID-based Signcryption Scheme with (t, n) Shared Unsigncryption
An identity-based signcryption scheme with (t, n) shared unsigncryption is proposed, which is the integration of the signcryption scheme, the (t, n) threshold scheme and zero knowledge proof for the equality of two discrete logarithms based on the bilinear map. In this scheme, any third party can verify the validity of the signature, but only more than t members in the recipient group can coope...
متن کاملA New ID-based Threshold Ring Signcryption without Random Oracles
Signcryption is a cryptographic primitive which could provide authentication and confidentiality simultaneously with a computational cost lower than signing and encryption respectively, while the ring signcryption has anonymity in addition to authentication and confidentiality. In order to design an identitybased threshold ring signcryption, this paper presented an efficient identity-based thre...
متن کاملAn Efficient Secret Sharing-based Storage System for Cloud-based Internet of Things
Internet of things (IoTs) is the newfound information architecture based on the internet that develops interactions between objects and services in a secure and reliable environment. As the availability of many smart devices rises, secure and scalable mass storage systems for aggregate data is required in IoTs applications. In this paper, we propose a new method for storing aggregate data in Io...
متن کاملVerifiable (t, n) Threshold Secret Sharing Scheme Using ECC Based Signcryption
In this paper, a secured (t, n) threshold secret sharing scheme has been proposed which prevents cheating from participants as well as from trusted dealer (TD) (which distributes shared secrets and reconstructs shared secret key). Here, a signcryption scheme based on elliptic curve cryptography (ECC ) which incorporates both the digital signature and encryption scheme in a single logical step i...
متن کاملEfficient Construction of Visual Cryptographic Scheme for Compartmented Access Structures
In this paper, we consider a special type of secret sharing scheme known as Visual Cryptographic Scheme (VCS) in which the secret reconstruction is done visually without any mathematical computation unlike other secret sharing schemes. We put forward an efficient direct construction of a visual cryptographic scheme for compartmented access structure which generalizes the access structure for th...
