A Privacy-Preserving User Authentication Scheme for WirelessSensor Network Users

Abstract

seamless roaming over wireless network is very attractive to portable clients, and security, for example,
verification of mobile clients is testing. As of late, because of alter protection and comfort in dealing with a secret word
record, some shrewd card based secure confirmation plans have been proposed. This paper demonstrates some security
shortcomings in those plans. As the fundamental commitment of this paper, a protected and light-weight verification plot with
client secrecy is introduced. It is easy to execute for mobile client since it just plays out a symmetric encryption/decoding
operation. Having this component, it is more appropriate for the low-power and asset restricted cell phones. Likewise, it
requires four message trades between mobile client, outside specialist and home operator. Therefore, this convention
appreciates both calculation and correspondence proficiency when contrasted with the outstanding confirmation plans. As
an uncommon case, we consider the confirmation convention when a client is situated in his/her home system.
In this paper, we propose a privacy-preserving all inclusive authentication protocol, called priauth, which gives solid client
obscurity against the two busybodies and remote servers, session key foundation, and accomplishes productivity. In
particular, priauth gives an effective way to deal with handle the issue of client renouncement while supporting solid client
untraceability.
