Research Interests
Cyber security including Security protocols, Forensics, Penetration Testing, Reverse Engineering and Networking including Satellite Networks, Internet, Adhoc networks, Mobile Networks, Cloud Computing, Mobile Cloud Computing etc.
 
Research Collaborations
Collaborating on research and projects with different researchers in CCSR, in industry and as well in different countries including my home country Pakistan.

Students Supervision
Supervised more than 10 MSc and undergraduate students before 2013 on different projects including IPsec, DTN, Multilayer IPsec, Bundle Security Protocol, Key Management, DoS Attacks etc. Currently, I am supervising some students in the area of Network and Mobile Forensics and Network Penetration Testing.

Projects (Technical Contributions)
Key Management in Delay/Disruption Tolerant Networking:
Contributed by proposing a new key transport protocol and new PKI Validation and Revocation Mechanism Suitable for DTN. 

Multilayer Security Architecture for Internet Protocol (ML-IPsec):
ML-IPSec enhances the functionality of IPSec in order to solve the conflicts between IPSec and intermediate entities such as TCP/IP and application layer PEPs.

Satnex II & III:
Suitability of DTN for different space scenarios including deep space, satellite based networks.

Secure Broadcast Authentication from IP Based Satellite Networks:
TESLA, FLUTE, ULE protocols implementation for satellite based multicast networks

VOIP and Unified Communication System:
evaluated Britannic Technologies existing SIP trunking system and proposed a more robust system design.

Optimization in Google Search Engine:
Semantic and ontology based optimization in Google search engine to extract specific information from web pages.

Other Protocols Implementation:
Peer to peer resource searching facility,
Routing Information Protocol (RTP),
Spanning Tree Protocol (STP),
POP3,
Steganography, Watermarking and Cryptanalysis algorithms and protocols.

Project Proposals
Contibuted in writing many research proposals for different funding bodies including ESPRC.
