본 논문에서는 센서 네트워크에 SPINS 보안 프로토콜을 적용하여 그 성능을 판별하려 하였다. 센서 네트워크의 보안을 유지하기 위해 SPINS에서는 SNEP과 ${\mu}TESLA$로 세분화 되어 데이터 인증, 보안과 키 관리를 각각 담당하게 된다. 본 논문에서는 그 중 SNEP을 nesC를 이용하여 TinyOS기반 센서에 적용하였다.

In this paper, the SPINS, a sensor network security mechanism, was researched to design a system to be applied to home network structure and check the security of which degree was ensured by a virtual network of home networking middleware. Sensor Network security mechanism SPINS provides data confidentiality and authentication by SNEP, and provides authenticated broadcast by ${\mu}TESLA$. We designed the system that applied SPINS to home networking middleware basic structure.

In this paper, a system with sensor network security mechanism which can be applied to home network structure is designed and it is implemented on a virtual network of a home network middleware. The basic structure of home networking middleware supports one-to-one (unicast) or broadcast communication mode between the lookup server and service nodes on the network. Confidentiality and authentication are key security factors of the one-to-one communication and user authentication is crucial for broadcasting mode. One of the sensor network's security techniques SPINS consists of SNEP and ${\mu}TESLA$. The SNEP ensures confidentiality and authentication, and ${\mu}TESLA$ provides broadcast authentication. We propose a SPIN based home network middleware and it is implemented by using the CBC-MAC for MAC generation, the counter mode (CTR) for message freshness, the pseudo random function (PRF) and RC5 as encryption algorithm. The implementation result shows that an attacker cannot decrypt the message though he gets the secure key because of CTR mode. In addition, we confirmed that a received message of the server is authenticated using MAC.
