Formal specification and analysis of security protocol is a research hotspot in network security at present. This paper models authentication service exchange of Public-Key Kerberos Protocol and an attack against this protocol with Petri nets. The Maria Tool automates analysis and verification of the model and finds that PKINIT-26 protocol has a security flaw. So we improve the model according to...
A comparative study of graphene nanoribbon MOSFET (GNR-FET) using the extended Huckel theory (EHT) and tight-binding (TB) is conducted within the frame of the self-consistent ballistic non-equilibrium Greenpsilas function (NEGF) formalism. The bandgap variation in armchair-edged GNR (aGNR) induced by the length of the edge bond, as well as the transport characteristics with bond length relaxation,...
