Encryption Tools

(OBJ 1.4)

Encryption Tools for Data Security

• TPM (Trusted Platform Module)

  • Dedicated microcontroller for hardware-level security
  • Protects digital secrets through integrated cryptographic keys
  • Used in BitLocker drive encryption for Windows devices
  • Adds an extra layer of security against software attacks
  • "Like a personal vault"

• HSM (Hardware Security Module)

  • Physical device for safeguarding and managing digital keys
  • Ideal for mission-critical scenarios like financial transactions
  • Performs encryption operations in a tamper-proof environment
  • Ensures key security and regulatory compliance
  • Not only does an HSM securely generate cryptographic keys, but it also provides accelerated cryptographic operations all within a tamper-resistent hardware device.
    • Even if the retailer system or databases were breached, the financial details about each transaction would remain safely encrypted due to the individual keys that are used by that hardware security module when encrypting that data that we're protecting using the system's encryption processes.
  • "Like a high security bank vault"

• Key Management System (KMS)

  • Generates, Manages, stores, distributes, and retires cryptographic keys
  • Centralized mechanism for key lifecycle management
  • Crucial for securing data and preventing unauthorized access
  • Automates key management tasks in complex environments
    • Managing unique encryption keys for a countless number of files manually would take years, but with the key management system you can ensure the system automatically manages those keys and refreshes them periodically to enhance security.

• Secure Enclaves

  • Coprocessor integrated into the main processor of some devices, designed with the sole purpose of ensuring data protection
  • Isolated from the main processor for secure data processing and storage of sensitive data
  • Safeguards sensitive data like biometric information
    • By keeping this data separate from the main processor, even if a device gets compromised, the data within the Secure Enclave remains untouched
  • Enhances device security by preventing unauthorized access
  • Example: Face-ID data is stored inside the Secure Enclave of your iPhone and it will never leave the device.
  • "A fortress inside of your device"
