The Privacy Protection Research Related To The Telemedicine System Based On Wireless Body Domain Network

In recent years,wireless communication technologies and wearable devices have developed rapidly as people pay more attention to the problems of health and aging population,and Wireless Body Area Networks are widely used in the field of remote medical care.In order to protect the privacy and life safety of patients,we need ways to prevent sensitive medical data from being accessed or even tampered by unauthorized participants while allowing access control technologies and identity authentication technology to be used in the telemedicine diagnosis system.However,the openness of transmission environment and the limited resources of nodes on the Wireless Body Area Network restrict the encryption mechanisms that can be supported on the Wireless Body Area Network,resulting in great challenges to the security and privacy protection during data acquisition,transmission,storage,and processing.The main work of this paper is based on the research of privacy protection of telemedicine system in Wireless Body Area Network.The technical method research focus on Man-in-the-middle attack,the serious threat of privacy protection on Wireless Body Area Network.The diagnosis systems have been designed,and the main points of the designing are mainly divided into access control and identity authentication.The specific innovative research results of this paper are mainly reflected in the following aspects:1.Based on the research of the existing WiFi man-in-the-middle attack technology method,a WiFi Man-in-the-middle attack mode is proposed,and according to the attack mode,we did the corresponding experimental simulation,which can automatically capture and analyze the playing flow of Android Youku APP for the user who connected the WiFi LAN and mined their video preference.2.The design scheme of telemedicine system with the function of classified privacy protection and identity-based anonymity is proposed,the temporary identity is utilized to realize anonymous consultation.the scheme enables different roles with access to differentcontents,i.e.the medical server cannot know the diagnosis made by the doctor,and the doctor cannot know the patients' true identify information;Several technologies such as ElGamal Encryption,Bilinear Mapping and Digital Signature are applied to provide the security features of anonymity,confidentiality,mutual authenticity,integrity and traceability.Performance analysis shows that the proposed scheme,which can reduce the computing cost and communication cost,is applicable to WBAN applications in terms of security and performance.3.The design scheme of the telemedicine system with the privacy protection function based on CP-ABE(Ciphertext-Policy Attributed-Based Encryption)is proposed,In this scheme,the patient sets the policy tree of CP-ABE before initiating a telemedicine request,which can limit the access control authority of the doctors to medical data;The medical server can undertake the encryption calculation of attribute-based key for the patient terminal,which can reduce the calculation overhead and communication overhead of the patient terminal;The doctor who has the attribute set satisfies the policy tree of CP-ABE can recover the attribute-based key and decrypt the encrypted medical data.The session key is used to replace the real identity of the patient to guarantee anonymity.The Hybrid cryptosystem and CP-ABE scheme protect the confidentiality.The digital signatures and Bilinear Pairing can also guarantee the authenticity,integrity and traceability.Performance analysis shows that the proposed scheme,which can reduce the computing cost and communication cost,is applicable to WBAN applications in terms of security and performance.Finally,this paper summarizes the advantages and disadvantages in our privacy protection telemedicine systems in the Wireless Body Area Network and looks forward to further exploration and research.
