Cryptographic Protocol with Keyless Sensors Authentication for WBAN in Healthcare Applications

Nowadays, technological advances provide people with more facilities and luxuries in life. Medicine is no exception; for example, different wireless sensors can be used to monitor patients’ state of health. These are the so-called Wireless Body Area Networks (WBAN), improve efficiency doctor-patient activities at any time, body area, anywhere. However, health data contains sensitive information that becomes a critical issue requiring special attention when transmitted within WBAN. In other words, WBAN must protected from malicious devices intercept, alter or access without authorization even deny being transmitted. this article, we present design new cryptographic protocol guarantees three security services, authentication, confidentiality, integrity by securing communication through We also consider keyless authentication method distinguish whether not placed on same individual’s body. A formal analysis carried out using verification tools guarantee its correct construction it provides appropriate security.
