About the Role
We are looking for a highly motivated GNSS Authentication & Security Engineer to join our team at VyomIC, where we are building the next-generation global LEO-PNT satellite constellation from India.
In this role, you will design, analyze, simulate, and validate authentication and encryption mechanisms for LEO-PNT signals and navigation services, with a focus on protecting PNT data against spoofing, unauthorized access, and signal manipulation. You will work at the intersection of GNSS security, cryptographic techniques, signal design, receiver algorithms, and system-level performance validation, contributing to the development of secure and resilient PNT services for VyomIC’s constellation.
Key Responsibilities
• Study existing GNSS authentication and encryption techniques, including OSNMA, TESLA-based schemes, digital signatures, MACs,



and encrypted spreading/signals.
• Define the security requirements and threat model for VyomIC's LEO-PNT signals, focusing on spoofing, navigation-message forgery, replay, and unauthorized access.
• Evaluate and recommend suitable authentication architecture for the LEO-PNT navigation message.
• Design how authentication data, keys, signatures/MACs, and associated metadata can be incorporated into the navigation message structure with minimal impact on data rate and TTFF.
• Develop MATLAB/Python simulations for authentication generation, transmission, verification, latency, overhead, and failure cases.
• Analyze security-performance trade-offs including message overhead, computational complexity, authentication latency, false acceptance/rejection, and receiver resource requirements.

Required Skills & Experience
• B.Tech/M.Tech in Computer Science, ECE, EE, Communications, Cybersecurity, or related fields.
• Solid fu
