Employment

Computer Security & Cryptography :

• Designed and implemented a Secure Socket interface in Java, with a provider mechanism to allow different implementations of Secure Socket (based on SSL, TLS or any proprietary protocol) to be plugged in. The interface is based on java.net.Socket family of classes in Java Development Kit. Exposed the native implementation of SSL on NetWare via the Secure Socket interface in Java. Co-developed a 100% pure java implementation of SSL, also exposed via the Secure Socket interface. The implementation, documentation and sample-code is available for download at Novell's DeveloperNet as part of Novell Developer Kit. A technical article on the same entitled "Novell SSL for Java" is published in Novell Developer Notes (November, 1999)
• Implemented Service Authentication on NetWare, to provide an NDS identity to software services running on a NetWare server. Services authenticated in this manner can securely access Novell Directory Services using their own identity, and the rights associated with it. Exposed the Service Authentication APIs in Java via Novell's authentication framework.
• Co-authored the architecture for security infrastructure of Virtual Communities based on Delegation of Rights and Permissions in a distributed environment.
• Designed and implemented a Secure Class Loader in Java, with support for signature verification on the classes.
• Exposition of Controlled Cryptography Services APIs (a service provider within Novell International Cryptography Infrastructure) in Java through the Java Cryptography Architecture (JCA) and Java Cryptography Extensions (JCE), involving design and development of a comprehensive SDK
• Designed Java APIs for the Generic Security Services (GSS).
• Studied a number of Security Proposals within Novell including Bottom up PKI, the Universal Authenticator, Multiple Authentication Framework etc.
• Implemented Service Authentication to NetWare Directory Services on NetWare in C and Java.
• Re-engineered the RSA algorithms of the Bsafe toolkit in Java. Involved understanding the C source code of Bsafe (licensed from RSA Inc.), evolving an Object Oriented Design for the toolkit, compliant with JCA (Java Cryptography Architecture) and JCE (Java Cryptography Extensions), and implementing the SHA-1 Message Digest Algorithm, RSA algorithms, and Signature algorithms using RSA with SHA-1.
• Re-engineered part of Novell's Secure Authentication Services framework in Java, involving Object Oriented redesign and implementation of Module Authentication and Binding Library Extensions (MABLE) framework from its C implementation.
• Re-engineered DES (Data Encryption Standard) in Java from its C implementation.
• Developed a good understanding of Java Security Architecture(JDK1.2), including Java Cryptography Architecture (JCA) and Java Cryptography Extensions (JCE 1.2)

Java and related Areas

• Been working on various Java projects for about 2 years, including OO design and implementation of required modules. Areas of applications have been Security, Cryptography, Directory Services, GUI development, Multi-threaded applications etc.

Directory Services :

• Co-authored the requirements for communication infrastructure of Personal Internet Directory (PID), an R&D initiative at Novell.
• Completed Object Oriented Design for one of the key components of PID -- Communication Engine, the gateway of communication between various directories. This required understanding protocols like LDAP, SMTP, POP3, HTTP, interfaces like JNDI, Java-Mail, MAPI, and concepts like distributed event processing, CORBA Event Services etc.
• Designed and implemented portions of GUI library for PID completely in Java. Implemented e-mail interface as part of PID-GroupWise intergration in Java.
• Developed a good understanding with NDS concepts/APIs, LDAP, and JNDI.

NetWare Advanced File Services (NSS -- Novell Storage Services)

• Designed and implemented test suites for about 25 % of the complete list of NAFS Server APIs to check the backward compatibility of these APIs with NetWare legacy file system. These tests run on NetWare OS as NLMs (NetWare Loadable Modules)
• Imparted a tutorial to other team members on NetWare programming fundamentals.

Professional Accomplishments

• Published an Internet-Draft with the Internet Engineering Task Force, entitled, " Architecture for Implementing Network Single Sign-On"
• Published an Internet-Draft with the Internet Engineering Task Force, entitled, "Complex Directory Lookup using Java based LDAP Query Extension"
• Published a technical writeup in Novell Developer Notes (January, 1999) entitled "Writing Java Applications on NetWare using Legacy NLMs". It has been translated to Polish as well.
• Published a technical writeup in Novell Developer Notes (June, 1999) entitled "Runtime Programming in Java: A Technology Primer"
• Published a technical article in Novell Developer Notes (November, 1999) entitled "Novell SSL for Java"

• Submitted Invention Disclosure for a technology proposal entitled "Secure Module Loader Architecture" in the capacity of Primary Inventor.
• Outstanding Contributions Award for active participation in the Management Initiative called "Issues Corrective Action Team" to make Novell Bangalore a better work place.
• Delivered Technology Talk on Emerging Networking Technologies to Computer Science undergraduates and postgraduates at a premier engineering school, the Indian Institute of Technology Kanpur (IIT Kanpur), India.
• Delivered a technology talk on Distributed Object Computing with CORBA with code samples to colleagues at Novell Bangalore.
• Successfully completed the Novell Java Training Programme. Imparted training to colleagues at Novell India on some of the key Java Programming Areas, such as AWT, Java Threads and Java Networking.

Undergraduate Project Work (Bachelor of Technology)

Title

• 3D Surface Reconstruction from Parallel Planar Contours -- Given the planar polygonal (possibly nested) contours representing the edge-trace of the cross-sections of a 3D object, the cross-sections being taken at parallel elevations, one has to reconstruct the 3D surface of the object and allow viewing and navigating through it on a graphical workstation. This problem has tremendous applications in areas of medical imaging, rapid prototyping etc.

Role

• Researched on various proposed heuristics to solve this problem and identified the merits and demerits of each.
• Selected the partial curve matching heuristic proposed originally by Barequet and Sharir and suggested appropriate modifications to address some of the major underlying lacunae.
• Designed and implemented from scratch the modified heuristic based on Partial Curve Matching followed by 3D dynamic triangulation. Extremely realistic output was generated for some real medical data of human organs such as the Pelvis Bone, Retina, Lungs, Chest, Skull, Brain etc.
• The Software was implemented in ANSI-C and used PHIGS graphics library and X-Windows/Motif based GUI.

Awards

• The project was declared the best undergraduate project in Computer Science and Engineering department of Indian Institute of Technology, Kanpur (IIT Kanpur)
• It was also honoured as the best undergraduate project, independently by Tata Consultancy Services, (TCS) India.

Publications

• Presented a paper on the improvements proposed to Barequet and Sharir's heuristic and other implementation considerations  at the CSI'96 conference (Computer Society of India). The paper was published in the conference proceedings of CSI'96.
