Abstract:

A method for clustering of nodes for a task, and cluster so provided comprising an automatically partitioned a set of nodes having a branched hierarchy of subsets based at least on a relative distance according to at least one node characteristic distance metric, each subset having a communication node, each node within the subset being adapted to communicate control information with the communication node, and the communication nodes of respective subnets which are hierarchically linked, being configured to communicate control information with each other; and a set of output preferred nodes for allocation of portions of a task, wherein the output set of preferred nodes is dependent on both the hierarchy and the task.

Abstract:

Computational grids have traditionally not scaled effectively due to administrative hurdles to resource and user participation. Most production grids are essentially multi-site supercomputer centers, rather than truly open and heterogeneous sets of resources that can join and leave dynamically, and that can provide support for an equally dynamic set of users. Large-scale grids containing individual resources with more autonomy about when and how they join and leave will require self-organizing grid middleware services that do not require centralized administrative control. Dynamic discovery of high-performance variable-size clusters of grid nodes provides an effective solution for implementation of grids. A brute force approach to the problem of identifying these “ad-hoc clusters” would require excessive overhead in terms of both message exchange and computation. Therefore, a scalable solution is provided that uses a delay-based overlay structure to organize nodes based on their proximity to one another, using a small number of delay experiments. This overlay can then be used to provide a variable-size set of promising candidate nodes than can then be used as a cluster, or tested further to improve the selection. Simulation results show that this approach results in effective clustering with acceptable overhead.

Abstract:

Signature-based authentication is a core cryptographic primitive essential for most secure networking protocols. A new signature scheme, MSS, allows a client to efficiently authenticate herself to a server. The new scheme is modeled in an offline/online model where client online time is premium. The offline component derives basis signatures that are then composed based on the data being signed to provide signatures efficiently and securely during run-time. MSS requires the server to maintain state and is suitable for applications where a device has long-term associations with the server. MSS allows direct comparison to hash chains-based authentication schemes used in similar settings, and is relevant to resource-constrained devices, e.g., IoT. MSS instantiations are derived for two cryptographic families, assuming the hardness of RSA and decisional Diffie-Hellman (DDH) respectively. Then used is the new scheme to design an efficient time-based one-time password (TOTP) protocol.
