Abstract. We argue that the needs of many classes of modern applications, especially those targeted at mobile or wireless computing, demand the services of content-based publish/su...
One of the most difficult problems to be solved by metacomputing systems is to ensure strong authentication and authorization. The problem is complicated since the hosts involved ...
The paper describes a metaobject architecture for distributed fault tolerant systems. Basically metaobject protocols enables functional objects to be independent from meta-function...
Based on the notion of accumulators, we propose a new cryptographic scheme called universal accumulators. This scheme enables one to commit to a set of values using a short accumul...
We present Gatekeeper, a decentralized protocol that performs Sybil-resilient node admission control based on a social network. Gatekeeper can admit most honest nodes while limiti...
