Light-weight and secure aggregation protocols

01-01-2018  In this section, we present two data aggregation protocols for distributed systems that provide confidentiality in the presence of a passive adversary that eavesdrops the communication. We consider a system consisting of a number of participants of the protocol, called stations, which share a secret key and a sink.

Private Over-threshold Aggregation Protocols over ...

Data Aggregation Data aggregation is one of important technologies in distributed systems, en-abling efficient utilization of resources. Thus many researchers in wireless and smart grid networks have focused on data aggregation schemes [18,10,33,15,28,34,11,21,22,30]. However, data aggre-gation is used in this paper differently.

Gossip-based Asynchronous Aggregation

In existing aggregation protocols, the accuracy and convergence of the estimated aggregate at local nodes heavily depends upon synchronization of aggregation rounds. Synchronization is not trivial to achieve and maintain in large-scale distributed P2P systems due to a number of factors such as different process execution speeds, message transmission delays, and clock drifts.

Robust Aggregation Protocols for Large-Scale Overlay Networks

Aggregation refers to a set of functions that provide global information about a distributed system. These func-tions operate on numeric values distributed over the system and can be used to count network size, determine extremal values and compute averages, products or sums. Aggrega-tion allows important basic functionality to be achieved in

Symmetric Push-Sum Protocol for Decentralised Aggregation

Aggregation protocols represent a decentralized paradigm for computing global properties of distributed systems. Sev-eral distributed aggregation protocols have been proposed in the last years. They can be divided into two main classes: Tree-based protocols and Gossip-based protocols. The former performs a tree-based communication

Gossip-based Asynchronous Aggregation

To execute such global functions which result in the aggregate capabilities of nodes, P2P systems require decentralized and distributed protocols without the coordination of a central mediator. For these reasons, gossip-based protocols have emerged as a popular choice to compute aggregates in

Epidemic-Style Proactive Aggregation in Large Overlay Networks

Aggregation in distributed environments The eld of distributed computation of aggregates is less established than epidemic protocols. An overview of the problem can be found in [13]. A prominent approach is Astrolabe [14] which is a hi-erarchical architecture for aggregation in large distributed systems. Anti-entropy aggregation is substantially different

AVCOL: Availability-aware information

28-08-2009  Aggregation of system-wide information in large-scale distributed systems, such as p2p systems and Grids, can be unfairly influenced by nodes that are selfish, colluding with each other, or are offline most of the time. We present AVCOL, which uses probabilistic and gossip-style techniques to provide availability-aware aggregation.

The pushsum protocol can be implemented into the distributed - systems whose goal is to compute the average from the values of all the entities present in a system. Within our considerations, we assume that the size and the character of a distributed system does not change during the whole process.

Distributed Data Aggregation protocol for

In this article, a Distributed Data Aggregation (DiDA) protocol for prolonging the lifetime of WSNs is suggested. DiDA protocol is an energy efficient approach for a clustered network. DiDA works into cycles and each cycle aggregates and reduces data dimensionality by using an Adaptive Piecewise Constant Approximation (APCA) method.

variants of aggregation protocols: Push-Sum (PS), Flow Update (FU), and Distributed Random Grouping (DRG). Despite the diverse data aggregation protocols introduced in literature [4], [6], [12], [14], we opt for the aforementioned protocols being well-known and most other protocols are variants using their core concepts.

Consistency Models and Protocols in Distributed

Consistency protocol is the implementation of a consistency model. Some main approaches include: primary-based protocols (remote write, local write) replicated-write protocols (active replication, quorum based) Primary-based Protocols. Primary-based protocols can be considered as a class of consistency protocols that are simpler to implement.

Consistency Models and Protocols in Distributed

Data replication is a vital feature in distributed system, but brings in an inevitable price to be paid: consistency maintenance. The consistency model specifies a contract between programmer and system, wherein the system guarantees that if the programmer follows the rules, memory will be consistent and the results of reading, writing, or updating memory will be predictable.
