Security is a crucial requirement in the applications based on information and communication technology, especially when an open network such as the Internet is used. To ensure security in such applications several security protocols have been developed. However, the design of complex security protocols is notoriously difficult and error-prone. Several flaws have been found on protocols that ar...

This thesis is divided into two distinct parts. The first part of the thesis explores security issues in key establishment protocols, including both key distribution protocols and key agreement protocols, and in both the general and the password-based setting. The second part of the thesis explores security issues of Timed-Release encryption schemes, especially those with a Pre-Open capability....

Security protocols are prescribed sequences of interactions between entities designed to provide various security services across distributed systems. Security protocols are often wrong due to the extremely subtle properties they are supposed to ensure. Deciding whether or not a security protocol assures secrecy is one of the main challenge in this area. In this paper we survey the most importa...
