A Key Establishment Scheme for Mobile Wireless Sensor Networks Using Post-Deployment Knowledge
Ashok Kumar Das
Establishment of pairwise keys between sensor nodes in a sensor network is a difficult problem due to resource limitations of sensor nodes as well as vulnerability to physical capt…
An Unconditionally Secure Key Management Scheme for Large-Scale Heterogeneous Wireless Sensor Networks
Ashok Kumar Das
Key establishment in sensor networks becomes a challenging problem because of the resource limitations of the sensors and also due to vulnerability to physical capture of the senso…
An Identity Based Key Management Scheme in Wireless Sensor Networks
Ashok Kumar Das, Debasis Giri
Pairwise key establishment is one of the fundamental security services in sensor networks which enables sensor nodes in a sensor network to communicate securely with each other usi…
An Improved Efficient Key Distribution Mechanism for Large-Scale Heterogeneous Mobile Sensor Networks
Ashok Kumar Das
Due to resource constraints of the sensor nodes, traditional public key cryptographic techniques are not feasible in most sensor network architectures. Several symmetric key distri…
Cryptanalysis And Further Improvement Of A Biometric-Based Remote User Authentication Scheme Using Smart Cards
Ashok Kumar Das
Recently, Li et al. proposed a secure biometric-based remote user authentication scheme using smart cards to withstand the security flaws of Li-Hwang's efficient biometric-based re…
