Problem Description

Hardware/Software based Solution for Interception, identification, demodulation and decoding of Burst signals in V/UHF frequency Range.

Burst signals of very short duration (ms/µs) is being transmitted in V/UHF frequency range from 30MHz to 3GHz. Signals spreads in wide frequency range (around 10 MHz each for uplink/downlink) for transmission. Requirement is to identify the burst communication and develop solution for demodulate and decode the same.

Testing

Solution can be developed taking test signals available on open source/provided by the user, however, final testing of the solution will be done on user samples only.

Evaluation Criteria

Estimation of RF parameters

Demodulation of the Signal into Bit Stream taking BER/SER into consideration

Estimation of coding schemes such as scrambling, FEC, protocols etc.

Final Decoding upto content level

Declaration of Winner

The winner will be declared based on the discretion of the Jury. The team whose solution is judged the best will be the winner. There can be joint winners also who will share the prize money in between.

Problem Description

A software-based tool should to be designed for classification of data being transacted over IP links. The software should be installed in a suitable hardware (server/ computer) machine to analyse the IP links of different capacities (ranging from few MBPS to 10 GBPS)

Testing

Testing : It is to be noted that students must use suitable traffic generators to generate mix of IP traffic at various rates for developmental and testing work.

Evaluation : The product/ tool will be evaluated on the synthesised IP traffic generated through suitable traffic generators. In the final testing round, traffic generators available at IITM may be used to generate mix of IP traffic and demonstrate system capability.

Evaluation Criteria

During evaluation the tool should provide following details:

Link Capacity/ Link rate- It should be able to detect the rate of traffic flowing in the link in terms of Line rate (bps- 1 Gbps/ 100 Mbps/ 10 Gbps), Bytes/ Sec, Packets/ seconds etc.

Traffic classifications based on Protocols- The tools should be able to classify the protocols which are present in the link. Example- POP3, IMAP, HTTPS, SMTP, TLS, SIP, RTPs etc

Percentage of clear/ unencrypted traffic in the link- It should be able to classify the percentage of clear and encrypted traffic in the link.

Traffic classification based on country specific traffic flow- It should be able to classify country wise IP traffic. The same can be done by checking the public IP addresses against the readily available IP allocation database.

Traffic classifications based on Port nos- The software should be able to indicate the port nos being used for IP communication.

Marking of traffic flowing between target countries (to be configurable). The software tool should be able to indicate traffic flow between target countries based on Source and destination IP addresses present in the packet. User should be able to select target countries.

The output of the system must be presented in graphical form using any suitable platform like Kibana or Grafana etc.

Declaration of Winner

The winner will be declared based on the discretion of the Jury. The team whose solution is judged the best will be the winner. There can be joint winners also who will share the prize money in between.

Problem Description
