T1 - Half a day Tutorial

Title: Introduction to Smart Cards
by Associate Professor, Dr. Vincent Guyot, ESIEA/LIP6, Paris, France
 

Abstract: The smart card has initially been created to secure exchanges between banks. It also secures the mobile telecommunication networks within each GSM terminal. Although the smart card technology has been extensively used for 30 years and is now standardized, only few people know what a smart card is and which benefits its usage could bring. This presentation will give an introduction to the world of smart cards. It will introduce the architecture of a smart card, present the recent APIs facilitating the usage of smart cards within software, and highlight the performance of new smart cards through examples. The objective of the session is to provide the presentation attendees with an in-depth understanding of smart cards and of what can be expected from their usage today.

Abstract: To accommodate the skyrocketing amount of traffic, optical network with wavelength division multiplexing (WDM) having several wavelengths per fiber as channels, is the most feasible solution. Transmission rate of a channel with 2.4, 10 or 40 Gbps is indeed achievable only in the electrical domain. With the advent of optical amplifiers in the mid 1990s and later on the feasibility of various types of optical switches, have enabled to consider the development of a new generation of optical networks in which optical signal with a given light path is routed without O-E-O (optical to electrical and electrical to optical) conversion and thus reduces the deployment time and produces additional network robustness. It has the advantage of eliminating the intermediate layer such as such as ATM and SONET/SDH. In a larger networks having more number of nodes, more wavelengths are needed and to avoid the large number of wavelengths the wavelength-routed networks overcome these limitations through wavelength reuse, wavelength conversion, and optical switching. The OXC (Optical Cross Connect), optical circuit switches (OCS), optical packet switches (OPS), and optical burst switches (OBS) techniques are considered where OXC produces the switching fabric for long term traffic demands. The OCS, OPS and OBS techniques require a light path to reconfigure automatically the switching fabric. Optical level switching (OLS) offers interoperability between OPS, OBS, and OCS and demonstrates successfully in Global optical network for multi-service applications. IP (Internet Protocol) backbone carriers are now connecting core routers directly over point-to-point WDM links (IP over WDM). This layer structure with a help of GMPLS (Generalized Multi Protocol Level Switching) and OXC (Optical Cross Connect) with IP packets are directly mapped into wavelength channels. The technologies for core networks (intercity), metro networks for MANs (intra-city), and local access networks for the services to the home or business, need rapid provisioning of connections within each subnet.

The numerous investigations have been carried out to solve routing and wavelength -assignments (RWA) problem in this DWDM networks considering the static light path system applying OXC-based networks and the dynamic light path system applied to OCS, OPS and OBS-based networks. The objective of the tutorial is to provide firstly the various investigations of optical transparency, mainly on optimization techniques related to RWA problem. The variation of quality of transmission (QoT) depending on RWA problem and hence for better network planning or better traffic engineering, will also be discussed. We consider the design of a network under long term traffic demands as OXC-based networks where as the dynamic traffic demands in OCS, OPS or OBS-based networks. In a second step, we describe the various devices for different components (Transponders, WDM multiplexers/de-multiplexers, amplifiers, optical fibers) to be required in a typical optical transmission system. Now-a-day there is a need to develop efficient optical components and devices relevant to the different optical networks with better (QoT). We shall discuss the router and routing techniques and different switches and their implementations. The different implementation methods of the switches are mechanical, MEMS, liquid crystals, bubble, waveguide type TO (Thermo-optic) and EO (Electro-optic) switches, wavelength routing switch (AWG and tunable ?), etc. These optical switches are very efficient and depending on size, capacity, speed, scalability, and cost one technology may prove superior to another, at least for specific needs. The advantages and disadvantages of electrical, Opto-electronics and optical switches and in-depth understanding for their requirements considering the limitation of the bandwidth between the links in different network systems will be discussed. The other waveguide type devices like modulators, attenuators, add/drop filters, couplers, power dividers and combiners, TE and TM mode splitters etc., required for optical networks, will be discussed considering their low losses and compact sizes. Now-a-day polymeric optical waveguide devices have attracted great interest in the field of integrated optics as it offers many advantages compared with other available waveguide materials because of their potential for easy, low-temperature and low-cost processing, highly tunable material index with large Thermo-optic coefficient. It also offers EO property with large Electro-optic coefficient. It possesses high nonlinear optical property for high speed and wide-band signal processing. The demand for low priced polymeric optical fibers (POF) is increasing due to their many short distance applications (10Gbps transmission over 100 meters) including fibers in home. Lastly, we shall discuss the networking of 21st century.

Abstract: Consider a set of parties who do not have trust in each other, nor in the channel by which they communicate. Even then the parties wish to correctly compute some common function of their local inputs, while keeping their local data secure from others. This, in a nutshell, is the problem of secure multi-party computation (SMC). This problem is fundamentally in cryptography and in the study of distributed computations. It takes many different forms depending on the underlying network, on the function to be computed, and on the amount of distrust the parties have in each others and in the network.

In this tutorial, we present several aspects of secure multi-party computation like privacy of Individuals, correctness of result and network traffic reductions. We first present the definition of this problem in various situations. Our definition is drawn from the previous idea and formulizations, and incorporate aspects that were previously overlooked. We also present several problems associated with SMC. Next we show the problem of hiding the data form trusted third party (TTP) which computes the result. We present the existing solutions of SMC along with the protocols developed by us. In our first solution, we introduced a randomly selected anonymizer between the parties and the TTP to hide the data. Apart from the randomly selection of anonymizer, the party will divide the data into number of packets and then send to different anonymizer so that the entire data will not reach to a single anonymizer and the privacy of individual will be maintained. After that, we present another problem, which enables the SMC to perform the correct computation of the result as well as the authentication of computational body. We have introduced multiple TTPs instead of a single one. If there is only one TTP then its behavior can be suspicious. Using this multiple TTP concepts we have the option to choose a TTP from domain of TTPs for computation. In this method we divide the data in several packets and these packets are sent to multiple TTPs and a randomly selected master TTP will perform the computation after accumulating data from other TTPs. For the authentication of TTP, we have introduced the concepts of equivalence classes. With the help of this concept we remove the malicious TTP from the system for further computation. Finally, present the problem of dealing with adversaries in SMC and minimizing their effects. We investigate the power of adversaries in several situations. We have also minimized the complexity of network traffic in entire process of SMC.
