The growth and adoption of Internet of Things (IoT), Industrial Automation and the widespread establishment of interconnected critical infrastructure are broadly transforming the Indian economic landscape. But, unleashes a serious attack surface and security is being turned into an IT wish list to a core engineering necessity. Analysis from Fact.MR positions embedded security as the critical factors of this transformation. Experts at Fact.MR study key challenges, the technological foundations of device-level protection, the business prospect of the Indian semiconductor companies, and the critical joint frameworks necessary to create a robust and secure industrial ecosystem of the country.
The Evolution of Embedded Security: From Afterthought to Core Enabler
The story of digitalization in India is rapidly shifting to secured connectivity. Initially, the primary goal was to get devices online and systems talking to each other, with security often bolted on as a software patch or a network-level firewall. This approach is proving catastrophically inadequate in an era where a compromised industrial controller can have physical, real-world consequences. Embedded security is now evolving into the non-negotiable core of any industrial or IoT deployment. It refers to the integration of security features directly into the hardware and low-level firmware of a device, the microcontroller, system-on-chip, or trusted platform module. This “security-by-design” philosophy is becoming a key enabler because the stakes in the operational technology realm are inherently higher, the sheer pervasiveness of IoT makes manual security management impossible, and regulatory pressures are beginning to mandate intrinsic device-level protection. Essentially, embedded security is the foundation on which India’s automated future is built.
Navigating the Security Conundrum: Major Issues for Manufacturers
For OEM and device manufacturers in India, integrating connected systems is a complex ballet of competing priorities. Our engagements with industry leaders reveal several persistent challenges that create a significant security conundrum. A primary hurdle is the perceived cost-performance trade-off, where robust security is often seen as an expensive addition that can impact device performance or power consumption, leading to it being value-engineered out in a price-sensitive market. To add to this is the gigantic requirement of ensuring security of legacy systems because the industrial landscape of India is a patchwork of contemporary and decades-old equipment which was not initially created to be interconnected and in most cases, does not have the computing power to support contemporary security standards. Moreover, electronics supply chains are global and complex and pose a great threat, where one breached element can lead to the creation of a backdoor in millions of devices. This is all exacerbated by a significant skills gap, with a shortage of engineers who possess deep expertise in both cybersecurity and embedded systems design, and the unique challenge of managing security over the long 15-20 year lifecycle of industrial assets.
The Technological Triad: Fortifying the Device Itself
A layered security strategy at the device level is essential in order to fight these challenges. The most effective strategy revolves around a foundational triad of technologies that work in concert to create an inherently resilient device. It starts with protection based on hardware, where Hardware Root of Trust is a secure, unalterable core of a chip that serves as a baseline to all security operations by producing, storing, and manipulating cryptographic keys in a confined space. This base provides secure boot which is a crucial activity that makes sure a device only runs the code that can be authorized and is not touched. The Hardware Root of Trust cryptographically verifies the digital signature of the first piece of code on power-up, and then permits the code to execute, forming a chain of trust, which stops the device in the event of any component being compromised. Lastly, trusted firmware or a Trusted Execution Environment, is a secure environment within the main processor, which is executed alongside the main operating system, separating and securing security critical tasks out of the remainder of the application. In a factory, this triad would guarantee that a sensor on a pipeline cannot be hacked and a robot arm in a factory will not execute unauthorized code, making security not at the network perimeter, but in the core of the device itself.
A Strategic Imperative: The Role of Indian Semiconductor Companies
The ‘Make in India’ edge and the government’s focused push into semiconductor manufacturing present a historic opportunity for domestic companies to become innovators in secure-by-design electronics, altering a national priority into a strategic advantage. The Indian chip designers are in a unique position to actualize systems-on-chips and microcontrollers that meet the needs and threats peculiar to Indian industry, such as cost-optimized but secure designs to the price-sensitive market and harsh environmental needs. One of them would be the creation and certification of indigenous Hardware Roots of Trust, which would decrease the reliance on external sources of these vital security cores and raise national security. In addition to the hardware, Indian companies can become leaders in creating high value security services, e.g., secure device provisioning and lifecycle management. The support of these safe design principles by Indian OEMs can help the companies to distinguish in the world, but they can even create a brand called Secured in India that would be a symbol of high quality and stability.
Forging a Resilient Future: A Collaborative Blueprint
The industrial ecosystem in India cannot be secured by any individual. The key roadmap to a strong future is a synergistic and mission-based collaboration between the government, industry, and academia. The government should serve as the facilitator in producing defined and outcome-focused cybersecurity standards of critical infrastructure and granting companies involved in the integration of robust embedded security, research and development and tax credits. The creation of nationally known testing laboratories to certify the embedded devices would develop a reliable standard of the entire industry. The implementer as an industry has a role to play in ensuring that it goes beyond minimum compliance but take the initiative of adopting the best practices of product security in the entire globe. Key actions include:
- Participating in sector-specific forums to share threat intelligence.
- Investing profoundly in training programs in order to fill the critical skills gap.
- Securing the product during the design process.
As an innovator, Academia should incorporate the hardware security and OT cybersecurity as central engineering studies and develop a university-industry collaboration to conduct applied research in next-generation threats and defenses
The quest to an India that is digitally enabled and industrially strong cannot be achieved without considering the security of its embedded systems. The problems are considerable, yet the technical solutions and the strategic directions are obvious. India can not only create smart infrastructure, but also create reliable and secure infrastructure through a hardware-first, security-by-design strategy, by taking advantage of the growing capabilities of the domestic semiconductor sector, and collaborating to create a shared national mission. To manufacturers, OEMs, policymakers, embedded security investment is no longer a technical aspect, but an essential investment in secure and sustainable economic future of India.
