Computing systems including hardware, software, communication, and networks are growing towards an ever-increasing scale and heterogeneity, becoming overly complex. Such complexity is getting even more critical with the ubiquitous permeation of embedded devices and other pervasive systems. To cope with the growing and ubiquitous complexity, Autonomic Computing (AC) focuses on self-manageable computing and communication systems that exhibit self-awareness, self-configuration, self-optimization, self-healing, self-protection and other self-x operations to the maximum extent possible without human intervention or guidance. Organic Computing (OC) additionally addresses adaptivity, robustness, and controlled emergence as well as nature-inspired concepts for self-organization. Any autonomic or organic system must be trustworthy to avoid the risk of losing control and retain confidence that the system will not fail. Trust and/or distrust relationships in the Internet and in pervasive infrastructures are key factors to enable dynamic interaction and cooperation of various users, systems, and services. Trusted/Trustworthy Computing (TC) aims at making computing and communication systems as well as services available, predictable, traceable, controllable, assessable, sustainable, dependable, persistent, security/privacy protectable etc. A series of grand challenges exists to achieve practical autonomic or organic systems with truly trustworthy services. Started in 2005, the series of ATC conferences has been held at Nagasaki, Vienna, Three Gorges (China), Hong Kong, Oslo, Brisbane, Xian, Banff, and Fukuoka. ATC 2013 will include a highly selective program of technical papers, accompanied by workshops, panel discussions and keynote speeches. Established as a premier venue in the area of autonomic and trusted computing, ATC 2013 will offer a forum for researchers to exchange ideas and experiences in the most innovative research and development in these challenging areas and includes all technical aspects related to autonomic/organic computing (AC/OC) and trusted computing (TC). The conference of ATC 2013 will be held in Vietri sul Mare, Italy which will be organized by Second University of Naples, Italy.
