Airport Authority of India
Aeronautical Fixed Telecommunication Network software connects all major airports in the world to exchange information on aircraft movements, conditions of airports, weather and other information related to Air Traffic Control. This System provides Comprehensive monitoring, handling and logging of all AFTN traffic. It provides Configurable message processing and color coding, Flight Plan Form with site-configurable templates, Fully automatic archiving and maintenance, Departure and arrival movement monitoring including Slot Monitor, Simple, intuitive operation. These areas include conducting a safety case analysis that identifies risks and mitigation plans, ensuring that security measures are implemented in order to protect the integrity of the AFTN from external unauthorized users. The use of appropriate logging and audit reporting required ensuring conformity and integrity of the service.
PROJECT OUTPUT VIDEO:
The purpose of this document is to provide guidance material for the use of the public Internet technology to support AFTN where required. This Working Paper presents the various issues that need to be addressed before implementing a system that uses the Internet as a delivery mechanism for AFTN. These areas include conducting a safety case analysis that identifies risks and mitigation plans, ensuring that security measures are implemented in order to protect the integrity of the AFTN from external unauthorized users. The use of appropriate logging and audit reporting required ensuring conformity and integrity of the service.
There are a number of small countries for which the uses of dedicated AFTN facilities are either not available or unaffordable. These ATS centers have been receiving and sending AFTN by fax or phone.
The costs associated with using the above method are high because the connection calls are charged at ISD rates. The process also is labour intensive may result in a higher than necessary workload for staff. These countries are ideally suited for which this Internet type of service delivery is more convenient and economical.
In existing system the ATS need fax and other recourses to tell about it the status of the flight and other information related to Air Traffic Control. So hackers may easily hack the information. So security issue arises. In proposed system we implemented the new technique to overcome the problem in existing system. In proposed system ATS center are fully automated and with high security. Here, (i.e.) in proposed system all information related to Air Traffic Control and flight status are send through mail and message which is in an encrypted format. The receiver should decrypt it by using key.
- AFTN Message sending
- Flight Details
- Flight Status
Login is the first module of the project. The login page helps us to navigate throughout inside the website. The login page is found as a link in the home page of AFTN website. After logging in, the user is provided with different links like AFTN message area, flight details, flight status and reports. This login consists of two sub modules namely
- User Authentication.
The registration page consists of various fields like username, password, email id and mobile number. These data are stored in the database and these data can be retrieved from the database when the login page can be accessed for the new users to navigate throughout the website. The username should be of alphabetic characters. Password can be of any character of user’s type. E-Mail id must be a valid e-mail of any prototype website. A valid ten digit mobile number is to be provided in the next mobile number field to send the mail sequence number to corresponding mobile when any AFTN message is received.
- USER AUTHENTICATION:
User Authentication is the main page for logging inside the website. This link is provided in the home page of the website. It consists of the username and the password field through which the user can login. The system checks with the database details already registered for the new user when the submit button is clicked. It thrives the user to the success page if the details provided are correct. Else the user is thrived to the error page to make user provide the correct details already registered. This page also allows the user to transact to the registration page in case of undefined new user.
- AFTN MESSAGE SENDING:
The next module is AFTN Message sending. The AFTN messages are those which are very important when considered according to airports authority. These messages consist of different types like NOTAM, FPL, ARR, DLY, CHG, EST, CNL, etc. They are the necessary flights related messages which are helpful to the airports authority employees in receiving the flight at their destination and to send a flight from their source. These messages are needed to be secured from unwanted hacking which may lead to hijacking of flights. Thus to send these messages in a secured way which is done is three different progress which are considered as the sub modules as follows
- Encryption and decryption.
- Sending as E-Mail
- Mobile Message Alert.
- ENCRYPTION AND DECRYPTION:
The message which is being composed in the AFTN message link is sent through public internet. Since it is using public internet as the communication medium, there becomes a threat to the hacking of messages or change of messages due to vulnerable virus transmission. Thus this project provides a best method in securing the messages while sending through the public internet. This project is using String Encryption technique, a new technique for securing the messages that are inbound for hacking.
This encryption technique uses a permanent public key both at sending and receiving airport authorities. This key is used for encrypting the messages in an iterative method. The public key can be of any characters like numbers, alphabets, symbols, alphanumeric characters, etc. The message is encrypted of each and every character of the public key decided by the authorities for sending secured messages to the destination. The characters are chosen in a random sequence for every message generated. This random sequence differs for every message and it acts as the private key. Thus the simple AFTN message is converted to the cipher text by iterative encryption.
The same reverse procedure is followed at the destination to decrypt the cipher text to the plain text. The decryption involves the same string encryption and decryption technique. The random sequence, which is the private key, is the necessary key for decrypting the cipher text. The cipher text is decrypted according to the sequence it is encrypted. Thus the original AFTN message is retrieved. Since a permanent secured public key is used for encryption the security for the messages are considerably increased in types of encryption. The hackers are unable to retrieve the message unless they have the public key which is known only to system that receives the message and the system that sends and not even known to the user who types the message.
- SENDING AS E-MAIL:
The encrypted message is converted to E-Mail format since it uses public internet as the medium of the communication. The sending process uses any prototype of the E-Mails that are specifically used by the airports authorities. This provides another security to the messages with e-mail encryption technique. Thus the iterative encrypted message is once again secured using the e-mail encryption technique. Thus the inbound hacking is prevented to the very extent of the security measures. The e-mails are received at the destination to the specified e-mail id which is downloaded to view the message.
- MOBILE MESSAGE ALERT:
Each and every message is being generated with a sequence number. This number is sent to the registered mobile number as a message to notify that the message has been received at destination. This uses mobile communication with Short Messaging Service (SMS) to send the sequence number to the required mobile numbers. This provides a notification for the arrival of the message at destination end. Thus all messages are view and the user can be aware of the messages that are lost or missed due to network failure or any other network attacks.
- FLIGHT DETAILS:
This provides the user to add up or edit the flight details in the log such that it can be viewed at any time for references. The flight details that are updated are stored in the database for future references. These details are archived for three days such that the details are deleted automatically after third day of the message. This module consists of the following sub modules.
- Addition of flight details.
- Updating and edition.
- ADDITION OF FLIGHT DETAILS:
The addition of flight details consists of the following fields like flight code, flight name, source, destination, time and date. The time and date are automatically updated according to the system time and it is programmed that it can be changed according to the users time and date revised by the airport authorities. The add button provides us the facility to add the details in the database which can be viewed by the tabular column provided below the fields of the flight details to be added.
- UPDATING AND EDITION:
This facility provides in editing of the flight details according to the authorities revised data. The manual delete facility is provided in the log file where the flight details are being displayed. This helps the authorities to delete unnecessary details from the database thus making database manually in emergency cases. Further automatic deletion of the details is done at every third day of the detail updated. This archiving facility is applied on both AFTN messages and flight details.
- FLIGHT STATUS:
The flight status can be viewed by the authorities in this website directly. When the connection of Metar section of the airports authority, the simulation of the selected flight can be viewed directly with the nodes available in its path of travel to the destination. This module consists of a sub module namely
This page is navigated from the flight details page. The detail of the flight is selected by enabling the check box found in the first column of the table found. Then the status of the flight is checked by clicking the status button. This provides the simulation of the flight from nodes between the source and destination. These nodes are obtained from the Metar section of the airport authority. Whenever the flight reaches the node it displays the node to which it has arrived in a message box. And the simulation is continued till the flight reaches the destination node. The speed of the flight traveling and the distance traveled by the flight is also displayed in the simulation page.
