Trustworthy Computing (TC) aims at providing secure, private, and reliable computing experiences in a world where computing has become a necessity for many aspects of life. While decades has passed since the concept of trustworthy computing was introduced for military, financial, and public safety related computing systems, trustworthy computing still remains one of the key issues in the design and operation of computing systems nowadays. The ever-growing complexity of computing systems, the shift of trust to a third-party cloud service provider, and the widespread use of computing devices have made it much more difficult to implement trustworthy computing. In view of the challenges, the TC workshop is formed in conjunction with QRS 2015 to call for innovative work on the design and application of trustworthy computing. Reviews and case studies which address state-of-art research and state-of-practice industry experiences are also welcomed.
