Here we report the development of a new cationic liposome–hyaluronic acid (HA) hybrid nanoparticle (NP) system and present our characterization of these NPs as an intranasal vaccine platform using a model antigen and F1-V, a candidate recombinant antigen for Yersinia pestis, the causative agent of plague. Incubation of cationic liposomes composed of DOTAP and DOPE with anionic HA biopolymer led to...
In this paper we show that it is possible to retrofit a security layer on top of PROFINET IO without changing the underlying transmission system or standards. By introducing security modules, end-to-end network security can be achieved and ensure authentication, integrity and confidentiality for real-time communication. The concept of security modules is a flexible framework and countermeasures can...
In this paper we show that it is possible to attack and gain control over PROFINET IO nodes and also that this can be done without any of the communicating peers detecting the attack. Analysis of attacks in both shared and packet switched networks show that the attacker can control the process data and thus the state of the machines connected to the I/O modules. As the security risks are increasing...
