Technical details and manufacturing context for Key Storage

Definition
A dedicated, tamper-resistant hardware module integrated into a cryptographic processor that provides secure generation, storage, and management of cryptographic keys. It protects keys from unauthorized access, extraction, or modification, even under physical attack, and is essential for operations like encryption, decryption, and digital signing.
Working Principle
The Key Storage typically consists of non-volatile memory (e.g., EEPROM, flash, or specialized secure memory) protected by physical security layers (e.g., metal shielding, mesh sensors) and logical security mechanisms (e.g., access control, encryption of the stored keys themselves). It interfaces with the cryptographic processor's core logic, which can request keys for operations but cannot directly read the raw key material without proper authorization. Keys are often generated internally via a True Random Number Generator (TRNG) and never leave the secure boundary in plaintext.
Common Materials
Silicon (for integrated circuits), Specialized secure memory cells, Metal shielding (for tamper resistance)
Technical Parameters
  • Key storage capacity, indicating the maximum number and length of cryptographic keys (e.g., AES, RSA) that can be securely held. (bits) Standard Spec
Components / BOM
  • Secure Memory Array
    Non-volatile storage for cryptographic key data, designed to resist physical probing and data remanence attacks.
    Material: Specialized semiconductor memory cells
  • Tamper Detection Mesh
    A network of sensors that detects physical intrusion attempts (e.g., drilling, etching) and triggers key zeroization.
    Material: Conductive polymer or metal traces
  • Access Control Logic
    Hardware circuit that enforces authentication and authorization policies before allowing key usage by the cryptographic core.
    Material: Silicon (logic gates)
