Title : Use of Bit 0x20 in DNS Labels to Improve Transaction Identity
Author(s) : P. Vixie, D. Dagon
Filename : draft-vixie-dnsext-dns0x20-00.txt
Pages : 8
Date : 2008-3-18
The small (16-bit) size of the DNS transaction ID has made it a
frequent target for forgery, with the unhappy result of many cache
pollution vulnerabilities demonstrated throughout Internet history.
Even with perfectly and unpredictably random transaction ID's, random
and birthday attacks are still theoretically feasible. This document
describes a method by which an initiator can improve transaction
identity using the 0x20 bit in DNS labels.
