Researched and benchmarked big integer Modular multiplication for asymmetric cryptography (RSA, ECC) with operand sizes up to 528 bits. Prototyped and validated algorithm correctness in Python; selected Montgomery multiplication for efficiency. Achieved 25% performance gain over Schoolbook multiplication for 256 to 521-bit sizes using Karatsuba, integrated Montgomery reduction to optimize modular multiplication on embedded microcontrollers. Developed complete AES-128 encryption and decryption algorithm from scratch, without using external libraries, demonstrating in-depth understanding of cryptographic internals. Implemented all core operations including Sub Bytes, Shift Rows, Mix Columns, Add Round Key, and Key Expansion, following the FIPS-197 standard. Exposure to understanding of Software Development Life Cycle (SDLC).
