+ - Comodo hack may reshape browser security-> 1

Microsoft's manager for trustworthy computing, Bruce Cowper, told CNET that the company is "investigating mechanisms to help better secure" certificate authorities, and Ben Laurie, a member of Google's security team, said the Mountain View, Calif., company is "thinking" about ways to upgrade Chrome to highlight possibly fraudulent certificates that "should be treated with suspicion."

Peter Eckersley, a senior staff technologist at the Electronic Frontier Foundation who has compiled a database of public Web certificates, says one way to improve security is to allow each Web site to announce what certificate provider it's using.

    All that SSL/DNSSEC/etc should be doing is A.Making sure that you are talking to the correct computer for the domain you are trying to access and not another computer wher
