Description
The Samsung S3FT9MG Java Smart Card is a Java Card designed for high-security scenarios. Based on the Samsung S3FT9MG secure payment chip, it integrates the Java Card technology architecture, supports Java Card API standards and APDU command interaction, and facilitates the deployment of secure applications on different hardware platforms. It supports Contact/Contactless/Dual Interface, JavaCard 3.0.1 and GP 2.2.2, and integrates encryption capabilities such as AES, DES/3DES, and RSA.
Key Technical Features:
The Samsung S3FT9MG chip deeply integrates Java card technology architecture and features a built-in JCOP (Java Card Open Platform) operating system, compatible with the Java Card API standard. This allows developers to deploy and run secure applet applications on different hardware platforms via APDU commands, achieving cross-platform compatibility.
The S3FT9MG operating system excels in encryption algorithms and security authentication, is designed for high-security scenarios, supports both international and Chinese cryptographic algorithms, and has passed authoritative security certifications, ensuring the confidentiality and integrity of data in complex environments.
The core encryption algorithms supported by this system include:
Symmetric encryption: AES (128/256 bits), DES/3DES, SM4 (Chinese national cryptographic standard), used for efficient data encryption transmission;
Asymmetric encryption: RSA (1024/2048/4096 bits), ECC (NIST P-256, secp256r1, etc.), SM2 (Chinese national cryptographic public key algorithm), suitable for digital signatures and key exchange;
Hash algorithms: SHA-1, SHA-256, SHA-384, SM3 (Chinese national cryptographic hash algorithm), ensuring data integrity;
Random number generation: True random number generator (TRNG) conforming to ISO/IEC 19790 standard, supporting the security of key generation.
In terms of security certification levels, the S3FT9MG has passed multiple international and industry authoritative certifications:
Common Criteria EAL6+: One of the highest security levels for high-risk environments, indicating its ability to resist advanced attacks (such as side-channel attacks and fault injection);
FIPS 140-2 Level 3: A US federal standard, certifying its physical security, key management, and tamper-proof capabilities;
EMVCo Certification: Meets global financial chip card interoperability requirements and supports the EMV contactless payment protocol;
National Cryptographic Level 2/3 Certification: Complies with China’s commercial cryptography management system and is applicable to key areas such as finance, government affairs, and transportation.
