An efficient mutual authentication and privacy prevention scheme for e-healthcare monitoring

Offline User Authentication Ensuring Non-Repudiation and Anonymity

“…To show that our scheme possesses superior properties, comparisons between authentication schemes ensuring anonymity [5,6,[11][12][13][14][15][16][17][18][19] and the proposed user authentication scheme are made as follows. Authentication schemes [5,[15][16][17] proposed for healthcare use biometrics as a factor to authenticate users, and this approach produces extra components to extract the biometrics needed. Authentication schemes were proposed for IoT applications [6,11,12], VANET [13,18,19], and cloud computing applications [13,14].…”

“…Authentication schemes were proposed for IoT applications [6,11,12], VANET [13,18,19], and cloud computing applications [13,14]. Users in these authentication schemes [5,6,[11][12][13][14][15][16][17][18][19] need to register with a trusted authentication server, and be authenticated online when accessing services, where users may be authenticated by the trusted authentication server directly or by other servers with the trusted authentication server's help. In the proposed scheme, a user/executive can be authenticated offline, and no extra component is needed.…”

“…When the user wants to access the system, he/she needs to use the issued mobile device or smart card to prove his/her legality to the system. Some authentication schemes adopting mobile devices or smart cards to enhance security have been proposed [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…The most significant advantage of these anonymous authentication schemes is to protect the user's identity and prevent other users from tracking and identifying a specific user. To comply with this special requirement, several schemes ensuring anonymity have been proposed [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”
