A non-malleable group key exchange protocol robust against active insiders
Desmedt, Yvo, Pieprzyk, Josef, Steinfeld, Ron, & Wang, Huaxiong (2006) A non-malleable group key exchange protocol robust against active insiders. Lecture Notes in Computer Science Volume : Information Security, 4176, pp. 459-475.
In this paper we make progress towards solving an open problem posed by Katz and Yung at CRYPTO 2003. We propose the first protocol for key exchange among n ≥2k+1 parties which simultaneously achieves all of the following properties:
Key Privacy (including forward security) against active attacks by group outsiders,
Non-malleability — meaning in particular that no subset of up to k corrupted group insiders can ‘fix’ the agreed key to a desired value, and
Robustness against denial of service attacks by up to k corrupted group insiders.
Our insider security properties above are achieved assuming the availability of a reliable broadcast channel.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
