Abstract

The Internet of Things (IoT) interconnects vast numbers of sensors and devices that operate under different cryptographic infrastructures, making secure cross-domain communication essential. Most existing signcryption schemes are designed for a single infrastructure or, at best, two fixed ones, which limits applicability in heterogeneous and evolving IoT deployments. To address this need, we introduce LH3SC, a seamless elliptic-curve heterogeneous signcryption scheme that supports three infrastructures: certificateless cryptography, public key infrastructure, and identity-based cryptography, with a CLC sender. LH3SC enables devices across these domains to communicate securely without major architectural changes. The security analysis establishes IND-CCA2 confidentiality and EUF-CMA unforgeability, and the performance evaluation demonstrates lower computation and communication costs than representative schemes. These properties make LH3SC suitable for resource-constrained IoT settings, including healthcare automation, smart grids, and other distributed systems that require seamless cross-domain security.
