A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : A DHCP Extension To Provide Initial Random Material Author(s) : Yaron Sheffer Paul Hoffman Filename : draft-sheffer-dhc-initial-random-00.txt Pages : 8 Date : 2013-12-04 Abstract: Some network devices get little or no entropy from their underlying operating systems when they are first started. As a result, cryptographic applications started before there is sufficient entropy in the operating system's pool can be initialized into a state that can be exploited by an attacker. This document defines a DHCP extension that can provide the operating system of a network device with some initial randomness that can only be known by an attacker who is on the same network segment as the device and its DHCP server. The operating system can mix this random input into its random pool early in the boot procedure and thus have more entropy available when cryptographic applications start. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-sheffer-dhc-initial-random There's also a htmlized version available at: http://tools.ietf.org/html/draft-sheffer-dhc-initial-random-00 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
