In this talk Yasemin Acar will outline her research that aims to bridge the gap between cryptography experts on the one side, and end users on the other side. Cryptography comes in many different shapes: we see it in password storage, digital signatures, encrypting files, and secure network connections. When implementations are less than ideal, security properties are lost. End users rarely have a chance to make informed choices about where to use which method of securing their data or communications, and crypto experts rarely implement the crypto all the way down to the application level that is actually used by end users. In-between are various actors, and their overarching problem can be summarized as “You are not your user”. Library developers, who implement crypto algorithms and make them available to software developers, may be crypto experts, but are rarely focused on library usability. Software developers, the users of crypto libraries, are rarely crypto experts, and are rarely focused on human factors to the degree that they can meaningfully communicate security features (or the lack thereof) to end users. Her research aims to connect the dots to secure end users by helping developers write secure code.
