Complex system-on-chip (SoC) requirements can include security at various application layers. The DesignWare Security Protocol Accelerator SMx (SPAcc-SMx) IP addresses the application space requiring the use of Chinese security algorithms SM3 and SM4.
The SPAcc IP offers high throughput with support for mixed packet size traffic and low latency to preserve quality of service in voice and video applications in single- and multi-core processor architectures. The product is highly customer configurable enabling solutions to be tuned for specific applications providing differentiation in the market.
Most security protocols require computationally intensive confidentiality (e.g., SM4) and authentication (e.g., SM3) algorithms to be applied to the data. The DesignWare SPAcc-SMx IP provides a framework to apply the algorithms that include a programmable sequencer, secure DMA engine, and cryptographic/hashing resources that can handle a variety of protocols.
The SPAcc-SMx product reduces the system bus traffic and increases throughput by supporting efficient data sequencing as well as parallel processing of cryptographic operations (authentication and encryption/decryption).
