Abstract:  The most challenging research area is now the  data security in communication network. Due to rapid growth in internet technology now it quite easy for anyone to tamper the data or to extract data from anywhere even though are lot of software as well as hardware protection. This issue was not so prominent may be  15 years before from now and we were safe  from any kind of data hacking. The security of data was not a major issue or problem but now it is a real challenge for the computer specialists.  We have to impose security of data in the same organization at different levels also. So this is a big challenge to everyone of us. Now the time has come when person ‘A’ can trust person ‘B’ but can not trust person ‘C’. So the security of data is now a big question. The confidential data may not be sent from one computer to another computer in raw form as there is no guarantee that no intruder will intercept the data during transaction. There was a time when people were using hardly any e-mail but now almost everyone is using e-mail. So e-mail is one communication system where the hackers always try to hack data and to manipulate data or try to access the data from a remote machine. We prefer to send important information by e-mail  from one person to another person. This is our fastest method to send data. But what is the guarantee that the data will not be modified or intercepted by some intruder or hacker? If the message is not encrypted then anytime the disaster may happen.  
The confidential data should not be sent in unencrypted form as it may be intercepted by some hacker. The encryption should  be done in such a way that the hacker can not apply any brute force method to retrieve the original data. e-Reservation, e-Banking and e-Business are now very  important application of IT  in communication network. While doing e-Reservation, e-banking or e-business the software designer  should be very careful about security of input data and the output data. Under no circumstances the  data may be tampered by any hacker. Cryptography is a subject which deals with how one can modify a readable text or any known object to unreadable text or document or some unknown object. In classical cryptography we have two types of  distinct algorithms : (i) Encryption algorithm and (ii) Decryption algorithm.  Encryption algorithm is used to make any readable format to unreadable format whereas the decryption algorithm does the reverse process that is from unreadable text back to readable text. The encryption or the decryption methods are of two types such as (i) Symmetric Key Cryptography where one key is used for encryption as well as decryption purpose which is also called the secret key and (ii) Public key cryptography where we use one key called public key for encryption purpose and another key called private key which is used for decryption purpose. The encryption key is distributed to all senders and the decryption key is distributed to the receiver only. In present tutorial we will try to discuss the various classical cryptography methods  including some recent trends in symmetric key encryption methods. The authors will also discuss the public key cryptography including RSA algorithm. Finally the authors will  also give a brief idea about  quantum cryptography.

Objective: The main objective of the tutorial is to discuss  and to implement some basic  cryptography methods. The authors  will discuss some very elementary methods of cryptography such as (i) Caeser Cipher method, (ii) Modified Caeser Cipher Method, (iii) Hill Cipher Method, (iv) Diffie hellman key exchange method, (v) Playfair method, (vi) Data Encryption Standard(DES) method, (vii)Advanced Encryption Standard(AES) method, (viii)Meheboob, Saima and Asoke(MSA) algorithm and some recent methods of symmetric key algorithm,(ix) DJSA method, (x) NJJSAA method, (xi) TTJSA method, (xii) DJSSA method, (xiii) DJMNA method, (xiv) Ultra Encryption Standard(UES), (xv) Bit Level Encryption Standar(BLES), (xvi)Modern Encryption Standard(MES) and also some public key algorithms such as (i) Rivest Shamir and Adleman(RSA) method. The authors will also discuss about (i) Message Digest, (ii) Digital Signatures,(iii)MD5, (iv)Secure Hash Algorithm, (v) Basics of Kerberos. At the end of the presentation the authors will give some live demonstration of some important cryptographic algorithms. The present tutorial will not help the beginners but also the experts in this field.

Intended audience:
The present Tutorial will cater three types of users:

    • The users those who are expert in different fields but they want to know the encryption algorithms and in future they may apply in their research work. The following category users will be very much benefited.  In fact these  users will be the main target group in this particular tutorial.
    • The users those who are expert in coding theory and cryptology they will also get some new information which will help in their future research work. 
    • There are many users in computers they mostly use the computer as an operator and they don’t have proper theoretical knowledge of computation. The present tutorial will also target those users. Even those who are non-computer professional they will also get some information which they may try to apply in their real professional lives.

The purpose of this talk is to raise awareness of the IT community on logistics problems in container terminals, where 90% of world trade goods are transported. Solving such logistics problems would potentially save up to 50% of the cost that we have to spend on goods.

The talk will show how ICT techniques, especially the combination of automation technologies with simulation/optimisation, can be used to significantly improve the performance of container terminals. Some case studies involving the process of developing an automated vehicle (for transferring containers) and applying it to some European ports will be presented. Here we will focus on how information technologies and decision science have contributed in bringing this product from the lab to the real environments.

The talk also attempts to attract audience’s attention on how the ICT techniques used in container terminals can be applied to other industries, and how IT solutions from other areas can be borrowed to apply to container terminals.

Quality of Service and Design Challenges in the Wireless sensor communications networks

Vivek Deshpande
Dean (Research and Development)
MIT College of Engineering, Pune, India.

Now-a-days Wireless Sensor Networks plays predominant role in the communication domain. The data to be disseminated from multiple sources to the destination base station or sink is having vital significance. There are many problems with which data can be conveyed up to the sink. The congestion, reliability, delay, fairness, etc. are of main concern. These can be treated as Quality of Service parameters that govern the performance of the WSN. Above all the Energy s consumption is the main constrain for WSN node. It is very difficult to obtain good QoS by keeping energy consumption low. Even if response of one of QoS parameter will depends on the many other QoS parameters. We have to take care of all QoS parameters to improve the performance of the wireless sensor networks. This Quality of Services may improve the application base of the WSN. With the QoS parameters the data dissemination along with energy optimization is get affected. We have to check the performance of the WSN against the QoS metrics for different data inputs. This may contain the periodic- non periodic data, event based data, transient or bursty data. For all these different types of inputs data we are checking the performance of QoS parameters like congestion, reliability and fairness. This may lead to new researcher to verify their results and excel their research work accordingly.
