An Analytic Model for Reducing Authentication Signaling Traffic in an End-to-End Authentication Scheme

In an end-to-end authentication (E2EA) scheme, the physician, patient, and sensor nodes authenticate each other Heart Rate Receiver through the healthcare service provider in three phases: the long-term authentication phase (LAP), short-term authentication phase (SAP), and sensor authentication phase (WAP).Once the LAP is executed between all communication nodes, the SAP is executed (m) times between the physician and patient by deriving a new key from the PSij key generated by healthcare service provider during the LAP.In addition, the WAP is executed between the connected sensor and patient (m + 1) times without going back to the service provider.Thus, it is critical to determine an appropriate (m) value to maintain a specific security level and to minimize the cost of E2EA.Therefore, we proposed an analytic model in which the authentication signaling traffic is represented by a Poisson process to derive an authentication signaling traffic cost function for the (m) value.

wherein the residence time of authentication has three distributions: gamma, hypo-exponential, Cap and exponential.Finally, using the numerical analysis of the derived cost function, an optimal value (m) that minimizes the authentication signaling traffic cost of the E2EA scheme was determined.
