Abstract: Unattended Wireless Sensor Networks face challenges in providing good security and in showing good performance. The lack of communication with the final data receivers is the main reason for this. It is possible for the UWSNs to gather the sensible data for long time. These data are vulnerable to adversaries who can compromise the sensors and maneuver the sensed data. This paper describes how various methodologies are used to act against the adversaries troubling the UWSNs. The various cryptographic measures have to take the vulnerabilities into consideration thus making the network improve its performance and security. In this survey paper, a detailed study about the various schemes that increase the efficiency and performance of UWSNs and the measures taken to improve forward security are given.
