Group key agreement in dynamic tactical networks
… part through message encryption using a common key. These networks are often wireless and ad hoc, that is they lack fixed infrastructure and communications are relayed in a multi-hop fashion. The mobility of the nodes leads to a highly dynamic and unpredictable network topology as well as a …

Minimax sampling for key agreement generation in body sensor networks
… usage in body sensor network (BSN) nodes during key agreement generation. In BSNs, it is important to secure communication between BSN nodes to ensure confidentiality, authenticity, and integrity of the information. The BSN node is faced with resource constraints such as insufficient memory …

Leveraging Smart Contracts for Asynchronous Group Key Agreement in Internet of Things
<p>Group Key Agreement (GKA) mechanism plays a crucial role in the realization of various secure applications in various networks such as, but not limited to, sensor networks, Internet of Things (IoT), vehicular networks, social networks, and so on. To be suitable for IoT, GKA must satisfy several …

Computational soundness for standard assumptions of formal cryptography
… In particular, we show how the Diffie-Hellman key-agreement scheme and the computational Diffie-Hellman assumption can be added to the Dolev-Yao model in a computationally sound way.

Attacks on multilinear maps
… these schemes with what is required for attacks. Key agreement seems to need certain features of multilinear maps which expose vulnerabilities while other applications like indistinguishability obfuscation. I analyze the attacks against these maps and show why they are not able to break the …

Implementation of Secure Key Management Techniques in Wireless Sensor Networks
… The communicating nodes must agree on secret keys in order to be able to encrypt packets. Sensor networks do not have many resources and so, achieving such key agreements is a difficult matter. Many key agreement schemes like Diffie-Hellman and public-key based schemes are not suitable for …

Security Architecture for the TEAMDEC System
The prevalence of the Internet, client/server applications, Java, e-commerce, and electronic communications offers tremendous opportunities for business, education and communication, while simultaneously presenting big challenges to network security. In general, the web was designed with little …

An integrated security Protocol communication scheme for Internet of Things using the Locator/ID Separation Protocol Network
… using Challenge-Response authentication and Key Agreement technique. Where, the third security protocol had been proposed, analysed and evaluated for the Internet of Things communication devices. This protocol was based on the authentication and the group key agreement via using the El-Gamal …

Generating secret in a network
… of information through the multiuser secret key agreement problem. A general notion of mutual dependence is established for the secrecy capacity, as a natural generalization of Shannon's mutual information to the multivariate case. Under linear-type source models, this capacity can be …

Security for network services delivery of 5G enabled device-to-device communications mobile network
… 3GPP specified protocols, 5G-Authentication and Key Agreement (AKA) and 5G Extensive Authentication Protocol (EAP)-AKA’ that provide primary authentication at Network Access Security (NAC). The research addresses Service Level Security (SLS) by proposing Federated Identity Management (FIdM) model …

Efficient Information Reconciliation for Quantum Key Distribution = Reconciliación eficiente de información para la distribución cuántica de claves
Advances in modern cryptography for secret-key agreement are driving the development of new methods and techniques in key distillation. Most of these developments, focusing on information reconciliation and privacy amplification, are for the direct benefit of quantum key distribution (QKD). In this …
