Technical details and manufacturing context for Encryption Engine

Definition
The Encryption Engine is a specialized hardware module integrated into the Protocol Processor Core, responsible for implementing cryptographic algorithms to encrypt and decrypt data during protocol processing. It ensures secure data transmission and storage by performing operations like AES, RSA, or SHA hashing at high speeds with minimal latency. The engine receives plaintext data and cryptographic keys from the processor core, applies configured encryption algorithms through dedicated logic circuits or co-processors, and outputs ciphertext. It operates via hardware acceleration to offload computationally intensive cryptographic tasks from the main CPU, enhancing performance and security in network or data processing applications. This component is fabricated using silicon with copper interconnects and dielectric materials, and is available in BGA or QFN packages. Key parameters include a throughput of 1–10 Gbps (AES-256-GCM, single core), latency of 10–100 µs for block sizes up to 2KB, and support for AES-128/256, RSA-2048/4096, ECC P-256, and SHA-256/512. Key sizes range from 128 to 4096 bits, operating voltage is 0.9–1.2 V, and power consumption is 0.5–2.5 W at max throughput. The operating temperature range is -40 to 85 °C, with a supply voltage tolerance of ±5%. Process technology is CMOS at 7–28 nm, and the footprint (die area) is 10–25 mm². Security certification references include FIPS 140-2 and CC EAL4+ (Level 2 or higher). These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier.
Working Principle
The Encryption Engine operates by receiving plaintext data and cryptographic keys from the Protocol Processor Core. It applies configured encryption algorithms, such as AES, RSA, or SHA, using dedicated logic circuits or co-processors. The engine outputs ciphertext after processing. Hardware acceleration offloads computationally intensive cryptographic tasks from the main CPU, improving performance and reducing latency. The engine supports symmetric and asymmetric key operations, with key sizes from 128 to 4096 bits. It operates within specified voltage and temperature ranges, and its throughput and latency depend on the algorithm and block size. The engine is designed for integration into network or data processing systems, providing secure data transmission and storage.
