Summary

The article discusses the importance of good random number generation in secure computer systems and how weaknesses in this process can lead to vulnerabilities. It highlights a hack on Hacker News, where an attacker exploited a weak seed used by the site's pseudo-random number generator to impersonate users. Random numbers are crucial for various cryptographic schemes such as SSL connections, WPA2 protocol, and secure email. The author mentions that CloudFlare is working on improving its random number generation system by incorporating truly random data from sources like radioactive decay or atmospheric noise.
