With the development of digital networks, such as Internet, communication protocols are omnipresent. Digital devices have to interact with each other in order to perform the numerous and complex tasks we have come to expect as commonplace, such as using a mobile phone, sending or receiving electronic mail, making purchases online and so on. In such applications, security is important. For instance, in the case of an online purchase, the right amount of money has to be paid without leaking the buyer personal information to outside parties. Communication protocols are the rules that govern these interactions. In order to make sure that they guarantee a certainlevel of security, it is desirable to analyze them. Doing so manually or by testing them is not enough, as attacks can be quite subtle. Some protocols have been used for years before an attack was discovered. Because of their increasing ubiquity in many important applications, e.g. electronic commerce, a very important research challenge consists in developing methods and verification tools to increase our trust on security protocols, and so on the applications that rely on them. For example, more than 28 billion Euros were spent in France using Internet transactions, and the number is growing. Moreover, new types of protocols are continuously appearing in order to face new technological and societal challenges, e.g. electronic voting, electronic passport to name a few.
