Changes In Deployment Of Cryptography, And Possible Causes

SSL/TLS is arguably the most widely deployed cryptographic protocol and is readily characterized. Last year my survey of over 8,000 SSL servers found that about 25% of them used only weak "export"-level keys and cipher suites. With the wider deployment of TLS, more high-speed cryptographic hardware, and another year since the U.S. liberalized crypto export regulations, more sites have deployed strong crypto. This talk will discuss the results of this year's survey, the changes in crypto deployment that have occurred in the last year, and the possible causes of those changes.
