Symptoms-Matching with Android based Healthcare Social Network for A Provably Secure Cross-Domain Handshake Scheme

Abstract

In this paper, we present a new framework for the handshake scheme in MHSNs, which is based on hierarchical identitybased cryptography. We then construct an efficient Cross-Domain HandShake [CDHS] scheme that allows symptomsmatching within MHSNs. For example, using the proposed CDHS scheme, two patients registered with different healthcare
centers can achieve mutual authentication and generate a session key for future secure communications. We then prove the
security of the scheme, and a comparative summary demonstrates that the proposed CDHS scheme requires fewer
computation and lower communication costs. We also implement the proposed CDHS scheme and three related schemes in
a proof of concept Android app to demonstrate utility of the scheme. Findings from the evaluations demonstrate that the
proposed CDHS scheme achieves a reduction of 18.14% and 5.41% in computation cost and communication cost, in
comparison to three other related handshake schemes.
