Technical details and manufacturing context for Cryptographic Engine Core

Definition

The Cryptographic Engine Core is the fundamental computational component of a cryptographic coprocessor, responsible for performing the core mathematical operations required for encryption, decryption, digital signature generation/verification, and key management. It operates as a specialized hardware accelerator, offloading these intensive tasks from the main CPU to enhance system security and performance. The core is typically fabricated on a silicon semiconductor wafer and integrates dedicated registers, arithmetic logic units (ALUs), and control logic optimized for fixed cryptographic functions. It supports common symmetric and asymmetric algorithms including AES, RSA, ECC, and SHA, with key lengths ranging from 128 to 4096 bits. Performance parameters, such as throughput (1–10 Gbps), latency (10–100 µs for block cipher operations), clock frequency (100–500 MHz), supply voltage (0.9–1.2 V), power consumption (0.5–5 W), operating temperature (-40 to 85 °C), process technology (7–28 nm), and die area (1–10 mm²), are provided as reference ranges that must be confirmed for the specific model and application. The core includes a true random number generator compliant with AIS 31 for cryptographic use, and incorporates hardware countermeasures against side-channel attacks such as DPA, SPA, and EMA, referencing ISO/IEC 19790. It interfaces with standard system-on-chip buses via AMBA AXI4. The core is designed for industrial-grade applications, and its specifications are intended for procurement and verification purposes. Always verify model-specific values and standards with the legal manufacturer or supplier before integration.

Working Principle

The core receives plaintext data and cryptographic keys as inputs. It then executes hardwired or microcoded sequences of mathematical operations (e.g., modular arithmetic, elliptic curve point multiplication, substitution-permutation networks) specific to algorithms like AES, RSA, ECC, or SHA. The processed output (ciphertext, hash, or signature) is then returned. It often includes dedicated registers, arithmetic logic units (ALUs), and control logic optimized for these fixed functions.
