Description
TheJ3R452 Java Smart Card is a secure dual-interface card for identity, payment, and authentication applications. It supports advanced cryptographic algorithms, PUF-based security, Java Card 3.0.5, and GlobalPlatform 2.3.1. With approximately 450 KB of storage, it enables flexible multi-application deployment and reliable data protection.
J3R452 Card Key Technical Features:
Enhanced Security Architecture: The Java Smart Card integrates Physical Unclonable Functions (PUF) to establish a unique hardware-level device identity binding, effectively defending against physical cloning and side-channel attacks.
Dual-Interface High-Speed Communication:As a Dual Interface Java Smart Card, it supports contact (ISO/IEC 7816) and contactless (ISO/IEC 14443 Type A/B) interfaces. Additionally, it delivers contactless speeds of up to 848 kbit/s and contact speeds of up to 688 kbit/s.
Support for Cutting-Edge Algorithms:
1. Newly added EdDSA (Ed25519) algorithm enables efficient, low-latency digital signatures, suitable for blockchain cold wallets and identity authentication scenarios.
2. Supports the SM4 national cryptographic standard symmetric encryption algorithm, meeting compliance requirements for China’s financial and government systems.
3. Asymmetric encryption supports ECC (up to 521 bits) and RSA (up to 4096 bits), compatible with NIST and Brainpool curves.
Large-Capacity Storage: With approximately 450 KB flash memory, this Java Card supports the deployment of complex applets and enables multiple applications to run securely on a single card platform.
Advanced Lifecycle Management: The J3R452 Java Smart Card supports Secure Channel Protocol SCP03, Delegated Management, and Executable Load File Upgrade, enabling secure card issuance and dynamic application updates.
FIPS 140-3 Certification: Complies with the latest US cryptographic module security standard, replacing the previous-generation FIPS 140-2, and enhancing international compliance.
