Traffic in Wireless Sensor Network (WSN) consists of short packets sent by nodes that are usually identical in respect of software applied and their hardware architecture. In such a communication environment it is important to guarantee authentication of the nodes. The most popular way to achieve this basic security service is using Message Authentication Code (MAC). The sensor node’s harbware is very limited so the cryptography used must be very efficient. In the article we focus on the influence of the authentication method’s performance on delays in data sampling by the sensor nodes. We present efficiency results for MACs generation in the node. We compare the results for approved, standardized and commonly-used schemes: CMAC, GMAC and HMAC based on MD5 and SHA-1. Additionally, we compare the obtained results with the performance of PKC-based authentication method using the ECDSA.
