Backers of IPv6 -- a long-anticipated upgrade to the Internet's main communications protocol -- have suffered another setback, as security experts punched holes in their planned strategy for supporting mobile communications. The discovery of security flaws in the proposed Mobile IPv6 protocol means the Internet Engineering Task Force (IETF) will have to develop a new method for authenticating roaming devices that use IPv6 addresses. This development means delays of months for Mobile IPv6, which was conceived a decade ago and thought to be in its final form.

The problems with Mobile IPv6 are frustrating for IPv6 proponents, who view wireless applications as the likely first adopters of IPv6. This frustration was evident at a meeting of the IETF's Mobile IP working group, which was held in Minneapolis on March 22.
