Secure Memory Module

Q: What is the Secure Memory Module used for?

It is a component in authentication systems that securely stores and processes sensitive data like cryptographic keys, biometric templates, and access credentials.

Q: What security features does it have?

It uses hardware-based encryption (AES-256), secure boot, and physical protection layers to create an isolated execution environment, protecting against physical and logical attacks.

Q: What are the operating temperature limits?

The industrial grade operates from -40°C to 85°C, with storage from -55°C to 125°C, per IEC 60068-2-1 and IEC 60068-2-2.

Q: How does it communicate with the main system?

It communicates via secure channels using interfaces such as SPI, I2C, or USB 2.0, and access to stored data requires proper authentication.

Technical details and manufacturing context for Secure Memory Module

Definition

The Secure Memory Module is a critical component of the Authentication Interface, designed to provide tamper-resistant storage and secure execution environment for authentication-related data. It operates as a dedicated hardware security module that isolates sensitive information from the main system, protecting against physical and logical attacks while ensuring fast, reliable access during authentication processes. The module utilizes hardware-based encryption, secure boot mechanisms, and physical protection layers to create an isolated execution environment. It stores authentication data in encrypted form, performs cryptographic operations within its protected boundaries, and communicates with the main system through secure channels. Access to stored data requires proper authentication and occurs only through controlled interfaces that prevent unauthorized extraction. The module is manufactured using silicon semiconductor technology, encapsulated in epoxy, and connected via gold bonding wires. It offers storage capacities ranging from 1 to 64 GB, with data retention of 10 to 25 years at 25°C (per JESD22-A117) and endurance of 100,000 to 1,000,000 program/erase cycles per block (per JESD47). Sequential read speeds are 100 to 400 MB/s, and write speeds are 50 to 200 MB/s. It operates in temperatures from -40°C to 85°C (industrial grade, per IEC 60068-2-1 and IEC 60068-2-2) and can be stored from -55°C to 125°C. Humidity tolerance is 5% to 95% RH (non-condensing, per IEC 60068-2-78). Supply voltage is 3.3 V DC ±5%, with power consumption of 0.5 to 3.0 W in active mode (standby <0.1 W). Tamper resistance is rated IP57 to IP68 (per IEC 60529). Encryption is hardware-accelerated AES-256 (per FIPS 197). Interfaces include SPI, I2C, and USB 2.0. Dimensions range from 20×15×2 mm to 50×40×5 mm. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The module creates an isolated execution environment using hardware-based encryption, secure boot, and physical protection layers. Authentication data is stored encrypted, and cryptographic operations occur within the protected boundaries. Communication with the main system uses secure channels, and access requires proper authentication through controlled interfaces, preventing unauthorized extraction.
