A novel method of concealing information is proposed. Encrypted data is mixed with noise to add the security. The cost of an attack increases linearly with the size of the added noise. Since generating noise is cheap, the size of noise can be as large as possible. However, there are issues in automatically detecting and separating noise in the intended recipient end. This stegocrypto method als...

We first provide an overview of the better known network approaches for assuring anonymity and privacy over networks. We then analyze possible attacks to these network based on traffic analysis techniques and discuss their implementation and design issues for network privacy. In the conclusion we discuss the results, indicating research opportunities in this domain.

We present the traffic analysis problem and expose the most important protocols, attacks and design issues. Afterwards, we propose directions for further research. As we are mostly interested in efficient and practical Internet based protocols, most of the emphasis is placed on mix based constructions. The presentation is informal in that no complex definitions and proofs are presented, the aim...

The growing complexity of telephone services, particularly in mobile telephony, and its impact upon billing data mean that phone call volume modelling techniques became crucial in the assessment of the accuracy of the information available in telecommunications data warehouses. Time series modelling, normally used for forecasting, provide a suitable tool for this purpose as well. Preliminary ex...

Realistic considerations of certain stochastic service systems often warrant the introduction of random changes in the intensity of the input process. A typical example of a changing arrival rate system is a communicat ion network with a sudden unpredictable increase in the traffic due to an external phenomenon. Such a situation can occur in a telephone network where a switching exchange node h...

Recent scholarly and policy discussions have focused on whether information communication technology (ICT) transport infrastructure enhance human development outcomes in developing countries. This study contributes to the knowledge by exploring impact of ICT using comprehensive panel data for 79 countries from 1990 2018. Applying two-step IV-GMM correct endogeneity, our results reveal that indi...

Real-time network traffic management is becoming more and more crucial in Telecommunications. In this paper, we propose a modular system based on neural networks, designed as an aid to the operator, for performing diagnosis at different levels of the network. In particular, we focus on the local diagnosis problem e.g. at the secondary transit centres of a telephone network. Statistical and neur...

Real-time network traffic management is becoming more and more crucial in Telecommunications. In this paper, we propose a modular system based on neural networks, designed to help the operator for performing diagnosis at different levels of the network. In particular, we focus on local alarm generation at the secondary transit centres of a telephone network. We finally consider some future exte...
