In order to secure communications for dynamic peer groups in mobile computing environments, key agreement protocols are required. In this paper, we propose a new key agreement pro...
Recent secure code-update protocols for sensor networks have been based on asymmetric-crypto primitives such as digital signatures. Our approach, Castor, explores the feasibility ...
: This paper proposes a context-aware security service providing multiple authentications and authorization from a Security Level which is decided dynamically in a context-aware en...
— In many traditional mobile network scenarios, nodes establish communication on the basis of persistent public identities. However, in some hostile and suspicious MANET settings...
Cryptographic hash functions are security primitives that compute check sums of messages in a strong manner and this way are of fundamental importance for ensuring integrity and au...
