“ Firmware development and testing for Optical Communication transceivers” A. TECHNICAL : Transceiver for Free space optical Communication,Channel Coding (RS code,Viterbi algorithm etc),Interleaving (2d / 3d),PLL. B. DIGITAL DESIGN : 1) IP ; 2) Memory Management ; 3) Bus : PCI ; 4) TOOLS USED : Altera Quartus II (13.1) Altera Quartus II (14.0 – Web edition) ,Modelsim,Signal TapII,Pin planner;5) BOARDS USED :Arria V , Cyclone IV

(RESEARCH) THRESHOLD IMPLEMENTATION OF PRESENT (Light Cryptography) SUPERVISOR : Fabrizio De Santis , Research Scientist (TUM - SEC) Main Scope: Reducing the number of shares so that the size of the crypto module is reduced. Previous implementations uses 3 shares which is 3 times the size of the basic implementation. Key Ideas Implemented : Irregular number of shares (2 shares – 3 share),Reducing the size by storing just 2 shares

THRESHOLD IMPLEMENTATION OF AES - SUPERVISOR : Fabrizio De Santis , Research Scientist (TUM - SEC) A. TECHNICAL INSIGHT ABOUT : Side channel Analysis (DPA),Shamir’s secret sharing,Threshold Implementation ,Masking PLAINTEXT and KEY,Galois Field, Leakage Resistant B. DIGITAL DESIGN : 1) Low power design; 2) Designing to reduce the size ; 3)Testing the design : Simulation tool,Gate level /Whole design/ and Board Testing; 4)TOOLS USED : Xilinx (ISE v14.6),ISim;5) BOARDS USED : SPARTAN 3E , SPARTAN 6

1) Involved in all stages of Software Development Life Cycle (2)Have experience in programming Microcontroller (ARM based) 3)Created modules with RTOS (FreeRTOS , emBOS etc) for microcontrollers 4)Basic understanding about ARM programming in C and assembler(5)Implemented data structures (stack, queue etc) in C, C++(6)Hands on experience in Preparing Unit test cases, test specification and test documentation(7)Assigned tasks for a small team of 5 members on both daily and weekly basis

Digital Design (VHDL), Cryptography(AES,PRESENT),Hardware security (Thresholding, Masking, Shamir's sharing), Testing digital circuits, Channel coding etc.
