Key Management Scheme for Smart Grid
… vulnerabilities to be thoroughly investigated. Key management is one of the most important security requirements to achieve data confidentiality and integrity in a SG system. It is not practical to design a single key management scheme/framework for all systems, actors and segments in the smart …

Available group key management for NASPInet
… it is critical to ensure fault tolerance of the key management infrastructure that the cryptographic primitives rely on. Since an entity might be sharing its data with multiple other power grid entities, group cryptographic primitives are more efficient and thus the keys must be distributed and …

A Framework for Secure Group Key Management
… and Internet communities. Secure group key management is concerned with the methods of issuing and distributing group keys, and the management of those keys over a period of time. To provide perfect secrecy, a central group key manager (GKM) has to perform group rekeying for every join …

Key Management Techniques for Dynamic Secure Multicasting
… and should not be able to decrypt it. Keys need to be distributed to the users belonging to the current session and hence some kind of key management is required. Existing schemes for secure multicasting are limited to small and static groups. To allow large and dynamic groups to use …

Energy efficient key management protocols to secure sensor networks
… To secure such a wireless network, the efficient key management techniques are important. Existing techniques assume energy and memory equipped nodes. This dissertation proposes energy efficient group key management protocols for secure sensor networks"--Abstract, page iii.

Context-sensitive key management for smart grid telemetric devices
… to generate new unique passwords and secret keys every time a pole device is accessed. In this work, we address the memory and computational constraint problem of measurement devices. Besides, we address the limited change management capability problem of the measurement devices and our …

Key Management for Wireless Sensor Networks in Hostile Environments
… compromising critical security data including keys used for encryption and authentication. Consequently, it is necessary to provide security services to these networks to ensure their survival. We propose a novel, self-organizing key management scheme for large-scale and long-lived WSNs, called …

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 …

Group Key Management in Wireless Ad-Hoc and Sensor Networks
… falsify information, collude to disclose system keys, or even passively refuse to collaborate. Moreover, mobile adversaries might invade more than one node and try to reveal all system secret keys. Due to these special characteristics, key management is essential in securing such networks. …

A practical key management and distribution system for IPTV conditional access
… was developed that draws from the area of group key management. Users are grouped according to their subscription selections and these groups are authorised for each selection's constituent services. Group keys are updated with a key-tree based approach that includes a novel method for growing …

Decentralized Key Management for Beyond 5G Network Coding-Enabled Mobile Small Cells
This thesis investigates decentralized key management and presents two novel decentralized key management schemes that are capable of providing secure communication in ad hoc-type networks and are agnostic to the network coding technology. The main research contributions of this thesis are …

IP ROUTING AND KEY MANAGEMENT FOR SECURE MULTICAST IN SATELLITE ATM NETWORKS
… and efficient methods to manage the encryption keys. This thesis attempts to solve the above problems for secure multicast in wide-area networks that have Ethernet LANs interconnected by ATM-based satellite channels. The thesis reviews the multicast services offered by IP and ATM and proposes a …

A Key Management Architecture for Securing Off-Chip Data Transfers on an FPGA
… a user over a secure serial interface, create a key with multiple layers of security, and encrypt an external memory interface using that key. In this way, the wrapper protects all of the digital interfaces of the embedded application from external analysis. Cryptographic methods built into the …

Design and Analysis of QoS-Aware Key Management and Intrusion Detection Protocols for Secure Mobile Group Communications in Wireless Networks
… develop three "threshold-based" periodic batch rekeying protocols to reduce the network communication cost caused by rekeying operations to deal with outsider attacks. Instead of individual rekeying, i.e., performing a rekeying operation right after each group membership change event, these …

A Framework for Providing Redundancy and Robustness in Key Management for IPsec Security Associations in a Mobile Ad-Hoc Environment
This research investigated key management in a Mobile Ad Hoc Network (MANET) environment. At the time this research began key management schemes provided limited functionality and low service availability in a highly partitioned ad hoc environment. The purpose of this research was to develop a …
