Rosetta SD/miniSD/microSD Series II

The Rosetta SD/miniSD/microSD Series II was a high-assurance hardware security module (HSM) offered in the familiar form factor of Secure Digital (SD), miniSD, or microSD media. Combining PKI with SD technology made it ideal for both embedded and enterprise applications requiring a small footprint, low power usage, and exceptional security.

About Product

High Assurance by Design

  • Based on the same chip and SPYCOS® operating system used in other highly secure Spyrus devices.
  • Extensive protection against physical tampering and side-channel attacks with active shield design, randomized memory, and hardware countermeasures.
  • Immunity to Branch Prediction Analysis attacks affecting PC-based cryptography.
  • Self-protection measures include zeroizing RAM on anomalies and safeguarding stored keys/variables in EEPROM.
  • Hardware-enforced delays and key zeroing to prevent PIN-guessing.
  • Full encryption of EEPROM storage during power-down or logoff, providing protection against sophisticated probing attacks.

High Assurance in Use

  • Built-in hardware random number generator, seeding a high-entropy DRBG for robust cryptographic key generation.

Enhanced Encryption Support

  • Surpasses U.S. Government Suite B standard, providing data security for decades to come.
  • Supports legacy algorithms for application compatibility.
  • Enables PKI functions: smart card logon, secure email, authenticated web browsing.

Additional Features

  • High-assurance protection for sensitive data, keys, and digital IDs.
  • SD/IO interface standard.
  • Unique serial number per device.
  • Approximately 32K of EEPROM for data and X.509 certificates.
  • Advanced random-number generation.
  • Anti-cloning support.
  • One Time Password (OTP) generation using OATH algorithm.
  • Tamper-resistant design to thwart physical attacks and reverse engineering.
  • Designed for FIPS 140-2 Level 2, 3, and 4 certification (depending on application requirements).
  • Compatibility with Microsoft CryptoAPI and PKCS #11.
