Key management is an important cryptographic primitive upon which other security services are built. Most of the existent pairwise key management protocols consider homogenous ad hoc sensor networks. However, recent researches have demonstrated the limitation of this architecture in terms of performance and scalability. Therefore, this paper focuses on proposing a pairwise key management protocol...
Key management in wireless sensor networks is still a challenging problem. Most existing research considers symmetric cryptosystems to achieve key agreement assuming homogenous network architecture. However, these solutions suffer from performance bottleneck and poor scalability. Recently, deployed sensor network systems are increasingly following heterogeneous designs. In this paper, we propose a...
Since 2006, many countries, all over the world, begin to issue e-passports containing biometric data for their citizens. The International Civil Aviation Organization (ICAO) specification for cryptography in e-passport is proven to be insecure and has many threats. The European Union (EU) has defined an extended access control (EAC) mechanism for e-passports. But, even this solution presents many...
