DNSSEC extends DNS with a public-key infrastructure , providing compatible clients with cryptographic assurance for DNS records they obtain, even in the presence of an active network attacker. As with many Internet protocol deployments, administrators deciding whether to deploy DNSSEC for their DNS zones must perform cost/benefit analysis. For some fraction(More)
In this paper, we explore the effectiveness of using graphical methods for isolating the differences between common application protocols---both in their transient and steady-state behavior. Specifically, we take advantage of the observation that many Internet application protocols proscribe a very specific series of client/server interactions that are(More)
Operating systems and applications rely on random number generators (RNGs) for a number of important tasks, most notably cryptographic key generation. The impact of flawed random number generation practices has been studied extensively in the past [2, 5]. In this paper, we examine the implications of an RNG bug in FreeBSD that was fixed by Subversion commit(More)
