About SLCOS
TrustSEC Smartcard Operating System
SLCOS is TrustSEC’s next-generation smart card operating system built on modern Java Card technology. It fully implements Java Card 3.0.5 and GlobalPlatform 2.2.1 standards, delivering an open, secure, and hardware-agnostic platform designed for enterprise and government deployments.
Engineered for flexibility and high-assurance environments, SLCOS enables organizations to deploy secure identity, payment, access control, and authentication solutions on a single card platform while maintaining full interoperability with global smart card ecosystems.
Standards & Compliance
SLCOS is built in alignment with globally recognized smart card standards, ensuring seamless integration into existing infrastructures and future-ready deployments.
- Java Card Platform: Fully compliant with Java Card 3.0.5 Classic Edition with backward compatibility
- GlobalPlatform: Compliant with GlobalPlatform 2.2.1 including Amendments D and E with full ID-Configuration support
- ISO Standards: Supports ISO/IEC 7816 (contact) and ISO/IEC 14443 Type A (contactless)
- Java Licensee: Developed under official Java Card licensing
- Certification Readiness: Designed to support GlobalPlatform certification and enterprise security validation programs
Open & Flexible Platform Architecture
SLCOS provides a true open platform architecture that allows organizations and solution providers to deploy secure applications without hardware dependency.
Hardware-Independent Design
Applications run on the integrated Java Card Virtual Machine (JCVM), enabling full hardware abstraction. Applets can be deployed across multiple chip platforms without modification, protecting investments and simplifying migration.
Modern Development Environment
Developers can build applications using standard Java Card APIs instead of complex native code such as C or assembly. This significantly reduces development time while increasing portability, maintainability, and security.
Multi-Application Capability
SLCOS supports secure coexistence of multiple applications on a single card. Through GlobalPlatform Security Domains and logical separation mechanisms, multiple service providers can deploy their applications safely within the same secure element.
Advanced Security Architecture
Security is at the core of SLCOS design, ensuring strong protection for sensitive credentials and applications.
- JCRE Firewall: Provides strict isolation between applets to prevent unauthorized data access or interaction
- Secure Security Domains: Enables controlled application lifecycle management and secure delegation to service providers
- Bytecode Verification: On-card verification ensures only valid and trusted applets are installed and executed
- Automatic Memory Management: Built-in garbage collection optimizes memory usage and system stability
- Secure Application Lifecycle: Supports secure loading, installation, personalization, and post-issuance management
Biometric
Biometric & Multi-Vendor Integration
SLCOS is optimized for biometric smart card deployments and supports integration with multiple biometric sensor and module vendors.
The platform enables secure on-card biometric authentication, allowing fingerprint or other biometric verification directly within the card environment. This ensures privacy-preserving authentication without exposing biometric data externally and supports strong multi-factor authentication for high-security use cases.
SLCOS is designed to support biometric payment cards, secure identity credentials, FIDO authentication tokens, and advanced access control solutions.
