stractions are extensively used to understand and solve challenging computational problems in various scientific and engineering domains. They have particularly gained prominence...
The popularity of "Trust-on-first-use" (Tofu) authentication, used by SSH and HTTPS with self-signed certificates, demonstrates significant demand for host authenticatio...
Recently, there has been much excitement in the research community over using social networks to mitigate multiple identity, or Sybil, attacks. A number of schemes have been propo...
Often, software architects impose a particular style on the software systems they design. For large software systems, they would like to ensure that the design continues to confor...
By looking on how computer security issues are handled today, dealing with numerous and unknown events is not easy. Events need to be normalized, abnormal behaviors must be describ...
In this paper we discuss PRNGs: the mechanisms used by real-world secure systems to generate cryptographic keys, initialization vectors, "random" nonces, and other values...
