This paper deals with a description of wireless sensor networks at the beginning. Further follows the introduction to the agent platform suitable for wireless networks. Mobile code and sensor networks suffer from considerable security problems. Our proposal of countermeasure is based on combination of smartcards with sensor nodes. Smartcards as a tamper resistant devices offer solution for the most of commonly required security objectives. Analysis of proposed hardware cryptographic platform includes link level communication, transport protocol description, application interface description and demands for power consumption. Today smartcards are highly standardized devices that offer common communication interface and platform could be used with various smartcards in accordance with ISO/EMV standards. At the end, we discuss the combination of agents in wireless sensor networks in conjunction with usage of cryptographic protocols for securing of wireless networks.
