Secure Socket Layer (SSL) certificates have made e-commerce more secure,
according to VeriSign, but a US security researcher reckons benevolent
rootkits served by the retailer might do a better job.

SSL certificates are issued to merchants by Certificate Authorities to
indicate to the consumer it is a legitimate business. The rootkit which Dan
Geer, VP and chief scientist at security company Verdasys, has proposed
would take over the security function of a customer during a transaction by
placing it within the merchant's trusted environment.

Geer proposes that merchants ask their customers whether they would like an
"extra special secure connection" prior to making a transaction. If a user
says "Yes", the merchant could install the rootkit on a customer's PC to
make the transaction safe.

Travesty alert:

"Extra special?" Yeah, well Sony tried that (without asking) and I can
assure you that any effort along these lines will end up the same way --
making consumers more vulnerable.

That is a very, very bad idea. And one that needs to be shot down now.
