Building Zero-Trust Environments with Biometric PKI Tokens & SLCOS

Zero-Trust Security is no longer a buzzword, it is a business imperative. As perimeter-based defenses crumble, modern organizations increasingly rely on hardware-rooted identity systems that verify every interaction, device, and session. TrustSEC’s unique combination of biometric PKI tokens and flexible SLCOS smart card operating system delivers this robust, zero-trust foundation. 1. What is Zero-Trust — and Why Software-Only Fails Zero-Trust rejects outdated “trust but verify” models. Instead, every access request must be authenticated, authorized, and encrypted regardless of origin. Relying on software-based credentials like passwords or OTP is becoming too risky: Phishing and malware can hijack credentials from devices. SIM-swap attacks enable attackers to intercept SMS-based OTPs; these surged 400% from 2020 to 2023. Complaints grow as enterprises recognize that software tokens introduce too many vulnerabilities. To thrive in a zero-trust world, hardware-backed identity is essential. 2. The Power of Biometric PKI Tokens TrustSEC’s biometric PKI tokens provide hardware-level protection and user-specific verification. Here’s why they are transformative: Biometric match-on-card (MoC) ensures that fingerprints are verified directly on the secure element; no data ever leaves the device. Secure storage of cryptographic keys prevents extraction via malware or remote attack. With FIDO2 smartcard compatibility, these tokens support passwordless login and strong authentication. This ensures every access request meets zero-trust standards. 3. How SLCOS Empowers Custom Solutions The SLCOS (Smartcard Operating System) platform serves as the engine powering TrustSEC’s security ecosystem: Supports Java Card / GlobalPlatform standards. Offers adaptability, IoT-optimized, biometric-enabled, PCI-compliant card OS. Simplifies feature implementation: FIDO2, PKI, PKC algorithms, C-PACE/D-CrEPT/Z-something for e-sign. This flexibility enables partners to build custom authentication solutions tailored for fields like finance, IoT, and public sector. 4. Real-World Use Cases Enterprise Access Security Organizations deploy biometric PKI tokens across employee devices. These tokens enable secure VPN and desktop login, enforce MFA without passwords, and comply with strong authentication mandates. IoT Device Authentication In IIoT environments, lightweight SLCOS applets verify device identity during firmware updates or data transmission. SLCOS’s small footprint and off-line capability make it ideal for edge deployments. Critical Infrastructure Airports, utilities, and government sites deploy biometric access control cards powered by SLCOS to secure gates, labs, and control rooms — even those that are air-gapped. 5.

Why Does This Matter to individuals and companies? The digital transformation of services, led people and businesses to use a dozen different mobile apps on a daily basis, As; apps for financial management, banks that require customers’ credentials, online shopping, etc.. The use of unprotected mobile applications have severe consequences on businesses and individuals. The threats of Mobile Apps hacking When a mobile application is compromised by malware or other hacking activity that exposes both the individuals and the companies to a high risk of being a victim of digital fraud. This includes… Possibility of stealing financial login credentials Credit card information stealing Hackers access to business networks Wholesale identity theft The usage of the hacked device as a mean of spreading malware to uninfected devices etc . . Such violations have many consequences that can be severe, including: Negative end-user experiences Negative, potentially permanent impact on the brand’s reputation Ongoing financial losses Unfortunately, 40% of organizations, including some Fortune 500, didn’t take active steps to protect their customers they’re developing the apps for. Only 50% of these same organizations dedicate any resources toward mobile app security. And the most recent reports indicate that up to 95% of mobile applications are vulnerable to attacks. Mobile Apps Security tips Testing As online fraud is constantly evolving, we recommend that companies should regularly test their apps for vulnerabilities, never rush development or patches, and monitor malware attacks. Mobile Application Security Practices Practices that expose individuals and companies to less mobile fraud threats. Only Download from Trusted Sources –We suggest downloading apps from the trusted app stores with high caution whenever downloading a new app, and the reporting of any suspicious activity.

COVID-19 and Secure online exams revolution!

The COVID-19 outbreak forced many countries to extend schools’ and universities’ closure to protect the safety and wellbeing of its employees, teachers, and students. The pandemic had a direct impact on the educational system overall, It is almost impossible for schools and universities to hold examinations. Many universities worldwide have suspended their exams and requested research papers instead. Considering these unprecedented circumstances, many educational entities have adopted online exams to support the students, so they can continue with their education journeys as soon as possible. To ensure fairness for all the students who have worked hard, and to continue the educational cycle, it was essential to use more layers of authentication to assure Identities in online exams & E-learning. It is essential to verify who is really taking the test. That’s why adding a security layer of authentication is essential to avoid cheating and confirm identities. The simple username and password authentication used in verifying the user identity used wasn’t secure enough as passwords can be easily shared or cracked. One-time password (OTP) and FIDO2 are more secure solutions and with the advancement in biometrics, it is more reliable to verify the physical presence of the enrolled learner at login and throughout the test session. About OTP (OTP) is a type of password that is valid for only one use. It is a secure way to provide access to an application or perform actions for only one time. The password becomes invalid either after a small time frame as it changes every certain time or no of clicks on used devices, devices could be software like Mobile application or hardware There are multiple ways to spread OTP with desired students, like Hardware devices, Mobile applications (Android – IOS), SMS, or Email. The most popular is the Mobile application and the most secure is the hardware device.

Forget your password – use your FINGERPRINT! match on card

Forget your password – use your FINGERPRINT! match on card match on card “Mr. Francis Galton affirms that ‘the patterns of the papillary ridges upon the bulbous palmar surfaces of the terminal phalanges of the fingers and thumbs are absolutely unchangeable throughout life, and show in different individuals an infinite variety of forms and peculiarities. The chance of two finger-prints being identical is less than one in sixty-four thousand million. If, therefore, two finger-prints are compared and found to coincide exactly, it is practically certain that they are prints of the same finger of the same person; if they differ, they are made by different fingers. – Lance”[1] The evolution of the smartcard – biometrics vs. two-factor authentication ( match on card ) Biometric smartcards are multi-factor authenticators (MFA). This is achieved through the addition of an extra layer of security; a fingerprint feature to authenticate the user in addition to the common two factors of authentication used – pin and hardware. The two-factor authentication solutions might expose users to fraud in the event that cards are stolen or pins are cracked. However, unlike standard smartcards, biometric smartcards enhance security on the card due to the probability of a biological feature of a person being identical with another person is less than one in sixty-four thousand million. Biometric smartcards can be thought of as turnkey solution that combines security, flexibility, durability and easy user experience. These cards achieve such security levels thanks to their onboard microprocessors processing the data directly, without remote connections. The biometric technology used depends on the Match-on-Card (MoC) that will store the holder’s biometric data and protect such communications with encryption. Biometric smartcards demonstrate a high level of flexibility as the technology used within the card is adaptable enough to integrate with any applet, is durable enough to last for many years, and provides user-friendliness; the card’s portability makes it easy for users to carry in their wallet. Biometric smartcards are the best solution in providing ultimate security to end-users. Especially in sensitive environments that require a high level of security in logical and system access. Such examples are governmental sectors, where biometric smartcards are used as accurate digital identification solution to access security-restricted buildings or access various government applications (border control, national identification cards, voter registration, and passports). Biometric smartcards also bring a security benefit to the healthcare sector where biometrics could be used by government-affiliated healthcare entities to access a patient’s medical records and ensure fraud prevention. The biometric data never leaves the card. match on card The technology used in TrustSec biometric smartcards eliminates cyberattacks by avoiding the vulnerability of storing the biometrics data on database servers. These servers may be based on insecure networks that are vulnerable to cyberattacks that might lead to abuse of the biometric data of a person. TrustSec biometric smartcards adopt Match-on-Card technology that eliminates the need for the database by both storing and processing biometric data directly on the secure microcontroller of the smartcard. Match-on-Card technology works by comparing the fingerprint presented by the user with the stored fingerprint in the secure environment, without having to send fingerprint data to a terminal or a remote server. Match-on-Card technology is typically performed in three steps, Fingerprint capturing (Acquisition), Features Extraction (Minutiae extraction) into a template Templates Matching. The Match-on-Card feature eliminates the risk of loss or theft of the cards entirely, as there would be no risk of the biometric smartcard being used without the unique fingerprint of its holder. Privacy comes first match-on-card Biometrics are biologically unique to the individual; therefore, once compromised, the individual has no recourse and is at a heightened risk for identity theft and therefore likely to withdraw from biometric enrolment. The majority of the population fear the loss of their identity through identity theft. This, in turn, has raised regulations governing secure biometric data collection, the use of such data and the processing of said data more complex. The gap between enterprises who wish to apply biometric technology and the unease of the users concerning such technology, is solved by the use of Match-on-Card technology to save the users’ identity while applying high-security measures in the enterprise at the same time. About TrustSec smartcard OS “SLCOS” match on card TrustSec smartcard OS is developing an open Java Card operating system that manages the smartcard resources as a principal component in the security chain; it protects the personal identity of the user and provides the required security services to the end-users. The OS works in conjunction with secure controllers from Infineon Technologies. It also allows third-party vendors to build embedded applications and applets without affecting security. The beta version was released in 2016 and TrustSec smart card OS has been in continuous development throughout the last five years over multiple Infineon controllers (SLE78 and SLC52) and is now planning to port its SLCOS to Infineon’s SLC38/B. SLCOS is now compatible with Java Card™ 3.0.4 and Biometry1toN Package from Java Card™ 3.0.5 is also implemented, as well as Global Platform 2.2.1 with MoC schemes (templates stored on the card, matching is done on card). TrustSec has entered into joint agreement with the leading biometric sensors providers in the market to supply biometrically enabled security solutions for identity management, access control, and payment authentication applications. In 2019, TrustSec collaborated with NEXT Biometrics to integrate their fingerprint sensor with TrustSec’s SLCOS operating system with a certified Common Criteria PKI applet providing the first version of its contact biometric smart card.
