【Abstract】It proposes a Hybrid Secure Signcryption Algorithm (HySSA), a small-size block chain (BC), and a planned system that secures an electronic health record (EHR) exchange through enabled device transmissions with minimal encryption and signature overhead. HySSA has two stages of operation. Patients are fitted with proximity sensor nodes (PSNs), which establish a wireless personal area network (WBAN) in the first phase of the procedure. It is up to the nodes to decide which cluster head (CH) in their vicinity can send data to the WBAN's Gateway sensor nodes (GSN) containing EHR meta-data. Second, GSN implements a lightweight signcryption technique for authorized stakeholders that combines data encryption and signing in the second phase of its development. An interplanetary file system provides secure keys for access to the data, which is exchanged over open channels (IPFS). Data mining results are stored to lower computing expenses, and block ledgers are used in global chain architectures. Compared to other schemes, the proposed HySSA scheme is cheaper for transaction and signing expense parameters, throughput of transactions, and computational and communication expenses. It takes HySSA a standard of 3.32 s (s) to sign and 6.52 s (s) to verify in simulation. It takes 3.325 s to mine 200 blocks, compared to 7.8 s for traditional schemes. The throughput of transactions was 142.78 Mbps, as opposed to the standard 102.45 Mbps. Computing time (CC) is 45.80 ms, while communication time (CCM) is 97 bytes, indicating that the suggested approach is competitive with other current approaches in terms of security.
