Structures for Communication-Efficient Public Key Revocation in Ubiquitous Sensor Network
نویسندگان
چکیده
In this paper we discuss the uprising problem of public key revocation. The main problem in key revocation includes the relatively large memory and communication required to store and transmit the revoked list of keys. This problem becomes serious as the sensor network is subjected to several constraints. In this paper, we introduce several efficient representation mechanisms for representing a set of revoked identifiers of keys. We discuss several network and revocation scenarios and introduce the corresponding solution for each. To demonstrate the value of our proposed approaches, practical simulation results and several comparisons with the current used revocation mechanism are included.

An efficient scheme for removing compromised sensor nodes from wireless sensor networks
Key management is a core mechanism to ensure the security of applications and network services in wireless sensor networks. It includes two aspects: key distribution and key revocation. Key distribution has been extensively studied in the context of sensor networks. However, key revocation has received relatively little attention. Existing key revocation schemes can be divided into two categori...
متن کاملKURCS: Key Updating for Removing & replacement of Compromised Sensor Nodes from Wireless Sensor Networks
An energy efficient key management scheme is an important aspect to ensure secure services in resource constrained Wireless Sensor Networks (WSNs). There are two parts of key management scheme, i.e. key distribution and key revocation. Key distribution is the task to manage the key in such a way that if two or more sensors want to communicate with each other for the purpose of sharing the data ...

Key management is a core mechanism to ensure the security of applications and network services in wireless sensor networks. Key management includes two aspects: key distribution and key revocation. The goal of the key distribution is to establish the required keys between sensor nodes which must exchange data. Key revocation is used to remove compromised sensor nodes from the network. Although ...
متن کاملHybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...
متن کاملSecret Key Revocation in Sensor Networks
Many challenging security-related issues have been studied in wireless sensor networks to provide a demanded quality and security for deliverable data. Yet, one of these issues which are not handled is the secret key revocation. In a semi-dynamic, resource-constrained and long-living sensor network with self organization features, traditional revocation methods are not desirable and somehow imp...
