{"title":"Security Architecture for At-Home Medical Care Using Sensor Network","authors":"S.S.Mohanavalli, Sheila Anand","volume":48,"journal":"International Journal of Health and Medical Engineering","pagesStart":1828,"pagesEnd":1832,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/3298","abstract":"This paper proposes a novel architecture for At-\r\nHome medical care which enables senior citizens, patients\r\nwith chronic ailments and patients requiring post- operative\r\ncare to be remotely monitored in the comfort of their homes.\r\nThis architecture is implemented using sensors and wireless\r\nnetworking for transmitting patient data to the hospitals,\r\nhealth- care centers for monitoring by medical professionals.\r\nPatients are equipped with sensors to measure their\r\nphysiological parameters, like blood pressure, pulse rate etc.\r\nand a Wearable Data Acquisition Unit is used to transmit the\r\npatient sensor data. Medical professionals can be alerted to\r\nany abnormal variations in these values for diagnosis and\r\nsuitable treatment. Security threats and challenges inherent to\r\nwireless communication and sensor network have been\r\ndiscussed and a security mechanism to ensure data\r\nconfidentiality and source authentication has been proposed.\r\nSymmetric key algorithm AES has been used for encrypting\r\nthe data and a patent-free, two-pass block cipher mode CCFB\r\nhas been used for implementing semantic security.","references":"[1] V.
