The wireless sensor network is a improved method of collecting the high sensitive information. In this paper discussion on various security methods is considered related to wireless sensor network. This paper is describing the fundamentals of secure data aggregation in wireless sensor network, identification of important parameters for the classification of secure data aggregation techniques in wireless sensor network , key characteristics of existing secure data aggregation techniques as well as comparing the existing secure data aggregation techniques with previous techniques. instead of this table of comparison based on various parameters such as security principles,prevention of attacks by protocols, aggregation functions. In addition to this cryptographic techniques which are used to secure data in wireless sensor network.

Wireless sensor network, centalized server, attacks, black node detection, encryption techniques, security methods.
