Abstract
Many cryptographic protocols were developed to support efficient group membership operations. Although those schemes can be extensively used for controlling temporary access with guest devices which do occur in many real world situations, those schemes incur a significant management overhead. For guest devices, we propose a scheme without heavy key management overheads-Temporary Access Rights Delegation (TARD). The proposed scheme uses a cryptographic token that can be securely constructed by a one-way function chain, used for granting a temporary membership to a guest device. Our analysis shows that the proposed scheme is theoretically secure and outperforms the certificate-based authentication schemes.
