WASH'13: The Workshop on Web Applications and Secure Hardware, London, UK, June 20th, 2013. (Submissions due 5th April 2013). http://wash2013.wordpress.com/ Web browsers are becoming the platform of choice for applications that need to work across a wide range of different devices, including mobile phones, tablets, PCs, TVs and in-car systems. However, for web applications which require a higher level of assurance, such as online banking, mobile payment, and media distribution (DRM), there are significant security and privacy challenges. Secure hardware -- such as TPMs, Arm TrustZone, virtualisation and secure elements -- is a potential solution, but is rarely made accessible to web applications or used by web browsers. The primary goals of the workshop are to identify challenges in the area of web applications and secure hardware, share early results, and identify new opportunities for research and development. We invite submissions on the following topics: * Trustworthy computing infrastructures for web applications * Improvements to existing web protocols and APIs based on secure hardware * APIs and standards for browser-based cryptography and access to secure hardware * Uses of secure hardware in web browsers * Security models for web applications involving secure hardware * Credential management and key storage in the browser * Web application authentication * Multi-screen secure web applications * Web browser access control and isolation techniques For more information see http://wash2013.wordpress.com/ .
