Smart Wireless Sensor Technology for Healthcare Monitoring System Using Cognitive Radio Networks

Programmable Object Interfaces are increasingly intriguing researchers because of their broader applications especially in the medical field In a Wireless Body Area Network WBAN for example patients health can be monitored using clinical nano sensors Exchanging such sensitive data requires a high level of security and protection against attacks To that end the literature is rich with security schemes that include the advanced encryption standard secure hashing algorithm and digital signatures that aim to secure the data exchange However such schemes elevate the time complexity rendering the data transmission slower Cognitive radio technology with a medical body area network system involves communication links between WBAN gateways server and nano sensors which renders the entire system vulnerable to security attacks In this paper a novel DNA based encryption technique is proposed to secure medical data sharing between sensing devices and central repositories It has less computational time throughout authentication encryption and decryption Our analysis of experimental attack scenarios shows that our technique is better than its counterparts
