The necessity to (re-)configure Internet of Things devices such as smart sensors during their entire lifecycle is becoming more important due to recent attacks targeting these devices. Allowing configuration parameters to be changed in any phase of a smart sensor's lifecycle allows security updates or new key material to be applied. Also, the functionality of a smart sensor can be altered by changing...
<?Pub Dtl?>Recently, considerable research has been performed in cryptography and security to optimize the area, power, timing, and energy needed for the point multiplication operations over binary elliptic curves. In this paper, we propose an efficient implementation of point multiplication on Koblitz curves targeting extremely-constrained, secure applications. We utilize the Gaussian normal...
We present the RUNES architecture for reconfigurable embedded networked systems and wireless sensor networks. It is the first systems-level architecture for such networks to explicitly deal with heterogeneity in hardware platforms, link-layer technologies and networking protocols while offering a simple programming language independent set of APIs together with a component-oriented middleware for...
As the networking technology greatly advanced in past decades, wireless sensor networks (WSN) have been widely deployed and utilized in various areas. Security issues on WSN devices thus draw much attention. In order to ensure the security of IEEE802.15.4 WSN and to fulfill the strict limitations of area and energy, we propose an efficient scheme for AES-CCM architecture. We implement AES-CCM by taking...
