A SSL cert vendor has a popularized writeup for 2048-bit RSA (which UEFI uses according to http://www.uefi.org/learning_center/UEFI_Plugfest_2012Q1_v3_AMI.pdf http://www.uefi.org/learning_center/UEFI_Plugfest_2012Q1_v3_...) at http://www.digicert.com/TimeTravel/math.htm http://www.digicert.com/TimeTravel/math.htm: "[...] It is therefore estimated, that standard desktop computing power would take 4,294,967,296 x 1.5 million years to break a DigiCert 2048-bit SSL certificate. Or, in other words, a little over 6.4 quadrillion years."
