A Novel Approach to Model NOW in Temporal Databases
In bitemporal databases, current facts and transaction states are modelled using a special value to represent the current time (such as a minimum or maximum timestamp or NULL). Pr...

Deciding Knowledge in Security Protocols for Monoidal Equational Theories
Abstract. In formal approaches, messages sent over a network are usually modeled by terms together with an equational theory, axiomatizing the properties of the cryptographic funct...

Automata and Logics for Words and Trees over an Infinite Alphabet
In a data word or a data tree each position carries a label from a finite alphabet and a data value from some infinite domain. These models have been considered in the realm of sem...

Tagging Makes Secrecy Decidable with Unbounded Nonces as Well
Tagging schemes have been used in security protocols to ensure that the analysis of such protocols can work with messages of bounded length. When the set of nonces is bounded, this...

Modal Logic over Higher Dimensional Automata
Higher dimensional automata (HDA) are a model of concurrency that can express most of the traditional partial order models like Mazurkiewicz traces, pomsets, event structures, or P...
