Malware signature builder and detection for executable code

Abstract: A method for implementing malware signature builder and detection for executable codes, according to which the op-codes of the executables are inspected, while disregarding other parameters of the executables-Signatures are generated from common engines of executable codes and a large number of malwares of the same family are represented by a small number of signatures. Then known and unknown malwares are identified using the small number of signatures.

Method and device for channel-adapted signal transmission in optical networks

Abstract: A method for optical data transmission in a wavelength multiplexing system having at least two transmission channels of different wavelengths includes determining at least one value which is a measure of a physical property of an optical data transmission path of the wavelength multiplexing system; and automatically adjusting a transmission parameter of at least one of the transmission channels as a function of the determined at least one value.

Information method and device for mobile subscribers

Abstract: Disclosed is an information method for mobile subscribers, whereby, on request and/or automatically, data are transmitted between a central control unit and a mobile subscriber unit. Also disclosed is an information device for mobile subscribers, encompassing at least one central control unit and a plurality of mobile subscriber units.

EC: an edge-based architecture against DDoS attacks and malware spread

Abstract: The ability to limit unsolicited traffic in the Internet is important to defy DDoS attacks and to contain the spread of worms and viruses. The concept of capabilities, which requires that sources must acquire tokens prior to sending data, has been successfully applied on an end-to-end base to protect end systems. In this paper, we propose Edge-based Capabilities (EC), an architecture that prevents DDoS attacks and malware spread at the edge. EC introduces a novel network element termed gate. The gate controls IP packets that have previously been authenticated by an end-to-end mechanism. Authenticated traffic carries a session-specific tag in the IP header. Packets with valid tags are forwarded by the gate whereas traffic without or with wrong tags is treated with low priority or even dropped. EC achieves efficiency and scalability by defining a single lock against which tags are compared, removing the need to store per-flow information in the gate. Compared to related proposals, EC is easy to deploy as the gate can be added incrementally and EC requires only a single network element to be added at the edge.

Mobile product customization

Abstract: Many companies are using the web to enable customers to individually customize their products that range from automobiles and bicycles to CDs, cosmetics and shirts In this paper we present a mobile application for product customization and production within a smart factory This allows the ad hoc configuration of products at the point of sale (POS) We investigate human factors when customizing products while interacting with them We focus on the concept of the mobile client that enables this ad hoc modification, but also present the production chain behind our product We believe that this particular 3D interaction with a product and a mobile device help to improve the customer satisfaction as it allows for customizing a product in an easy and intuitive way From a CHI perspective an important aspect is that our mobile augmented reality interface can help to match the costumer's expectations with the final modified product and allows the most natural and intuitive interaction As a use case of the system, we present the modification of a soap dispenser
