JavaCard and GlobalPlatform Security

[Cloned Boy]

JavaCard and GlobalPlatform are two key technologies that provide security and application management on smart cards. These platforms are widely used in bank cards, SIM cards, ID cards and other secure devices. Let's look at how they work from a security perspective.

1. What is JavaCard?​

JavaCard is a platform for running Java applications (applets) on smart cards. It allows developers to create secure applications for working with sensitive data such as encryption keys, PIN codes, and payment data.

Key security features of JavaCard:​

a) Isolated execution environment​

• Each applet runs in its own sandbox, which prevents one applet from accessing another's data.
• This reduces the risk of attacks such as code injection or unauthorized access.

b) Secure data storage​

• Data is stored in secure memory (EEPROM), which is protected from physical access and software attacks.
• Sensitive data (such as encryption keys) are stored in encrypted form.

c) Cryptography​

• JavaCard supports modern cryptographic algorithms:
  • Symmetric algorithms: AES, DES.
  • Asymmetric algorithms: RSA, ECC.
  • Hash functions: SHA-256, SHA-3.
• This allows for encryption, digital signature and authentication operations.

d) Resistance to attacks​

• JavaCard is designed to protect against various types of attacks:
  • Third-party channels: Protection against power consumption and execution time analysis.
  • Physical attacks: Protection against attempts to extract data using microscopy or x-ray analysis.
  • Logical attacks: Protection against buffer overflows, code injection and other software vulnerabilities.

2. What is GlobalPlatform?​

GlobalPlatform is a standard for managing the lifecycle of applications on smart cards. It provides tools for downloading, installing, updating, and removing applets in a secure environment.

Key security features of GlobalPlatform:​

a) Safe loading of applets​

• Applets are loaded onto the card via a secure channel (Secure Channel Protocol, SCP).
• Encryption and authentication are used to prevent data from being intercepted or tampered with.

b) Separation of access rights​

• GlobalPlatform defines roles and rights for different participants:
  • Card Issuer: Issues the card and manages basic settings.
  • Application Provider: Loads and manages its applets.
  • Security Domain: Provides isolation between applets from different providers.

c) Life cycle of applets​

• Applets go through several stages in their life cycle:
  • Loading: The applet is loading onto the card.
  • Installation: The applet becomes available for use.
  • Activation/Deactivation: The applet may be temporarily disabled.
  • Removal: The applet is completely removed from the card.
• Strict safety rules apply at every stage.

d) Data encryption​

• All data transmitted between the card and external systems is encrypted.
• Protocols such as SCP02 and SCP03 are used to ensure data confidentiality and integrity.

3. JavaCard and GlobalPlatform Collaboration​

JavaCard and GlobalPlatform often work together to provide comprehensive security:

a) Managing applets​

• GlobalPlatform manages the process of downloading and installing applets, and JavaCard ensures that they run in a secure environment.

b) Data protection​

• GlobalPlatform encrypts data during transmission, and JavaCard protects its storage and processing.

c) Multitasking​

• GlobalPlatform allows multiple applets to coexist on a single card, and JavaCard provides isolation between them.

4. Potential threats and methods of protection​

a) Physical attacks​

• Threat: Attackers may attempt to extract data from the card using microscopy, X-rays, or other methods.
• Protection: Using protective layers on the chip, self-destructing data when an attack is detected.

b) Logical attacks​

• Threat: Injection of malicious code or exploitation of vulnerabilities in applets.
• Protection: Isolation of applets, code checking for vulnerabilities.

c) Third party channels​

• Threat: Power consumption or execution time analysis to obtain secret data.
• Protection: Use of technologies such as masking and random execution time modification.

d) Social engineering​

• Threat: Attackers may try to trick the user to gain access to the card.
• Security: Educate users on security basics.

5. Examples of JavaCard and GlobalPlatform Applications​

a) Bank cards​

• EMV cards use JavaCard to run payment applications and GlobalPlatform to manage those applications.

b) SIM cards​

• SIM cards use JavaCard to run carrier applications and GlobalPlatform to securely download new services.

c) Identity cards​

• Electronic passports and driver's licenses use these technologies to store biometric data.

d) Transport cards​

• Contactless travel cards use JavaCard and GlobalPlatform to securely process transactions.

6. The Future of JavaCard and GlobalPlatform​

Technologies continue to evolve to protect against new threats:

a) Support for new standards​

• Integration with modern protocols such as TLS 1.3 and Quantum-Resistant Cryptography.

b) Improving performance​

• Optimized for use on devices with limited resources.

c) Expansion of areas of application​

• Use in IoT devices, blockchain and other new technologies.

7. Conclusion​

JavaCard and GlobalPlatform provide high levels of security for smart cards and other secure devices. They protect data from physical, logical, and third-party attacks, and provide tools for secure application management. Despite the constant evolution of threats, these technologies remain a reliable choice for protecting sensitive information.

JavaCard and GlobalPlatform Security: Protecting Smart Cards and Payment Systems​

JavaCard and GlobalPlatform are key technologies that ensure the security of bank cards, SIM cards, electronic documents and other smart cards. Let's look at their security mechanisms.

1. JavaCard Security​

JavaCard is a platform for running Java applets on smart cards (EMV chips, eSIM, electronic passports).

Basic defense mechanisms:​

✔ Isolated execution environment (Sandbox)

• Each applet runs in its own protected space.
• No access to other applets' memory.

✔ Cryptographic protection

• Support AES, RSA, ECC, SHA-256 .
• The keys are stored in the Secure Element (cannot be extracted).

✔ Hardware protection

• Protection against DPA/SPA attacks (energy consumption analysis).
• Physical non-removability of keys .

✔ Certifications

• Common Criteria EAL 4+/5+ (high confidence level).
• EMVCo, PCI DSS for payment systems.

2. GlobalPlatform Security​

GlobalPlatform is a standard for managing applications on smart cards (downloading, deleting, updating).

Key security features:​

✔ Secure Channel Protocol (SCP)

• Encryption of data between the card and the terminal (SCP02, SCP03).

✔ Rights Management

• Access restrictions for applets (for example, a payment application cannot read SIM data).

✔ Protection from unauthorized download

• Only signed applets can be installed.
• Control via Security Domain (Issuer, Provider).

✔ Attack Monitoring

• Blocking the card during a hacking attempt.
• Logging of suspicious transactions.

3. How is this applied in bank cards?​

1. EMV transactions
   • Generate dynamic cryptogram for each payment.
   • Checking the PIN code without transmitting it to the terminal (Offline PIN).
2. Multi-application
   • The following can work on one card:
     • Payment application (Visa/Mastercard).
     • Transport (Troika, Podorozhnik).
     • ID (electronic passport).
3. Protection from cloning
   • Even if an attacker obtains the data, without Secure Element the copy will not work.

4. Vulnerabilities and protection​

Possible attacks​

• Physically hacking the chip (expensive and difficult).
• Side-channel attacks (electromagnetic radiation analysis).
• Logical vulnerabilities (errors in applets).

How do they defend themselves?​

• Hardware HSM for key generation.
• Regular updates (OTA for SIM, bank cards).
• White-box cryptography (protection of keys in software).
