The invention discloses a high-speed security chip architecture and a high-speed data processing method based on a PCIE interface. The high-speed security chip architecture integrates a bus, a CPU, asecure storage unit, a DMA, a cryptographic operation unit, and a high-speed PCIE interface unit on a chip which is only necessary to use one chip to complete the full function of the security chip. The high-speed security chip architecture based on the PCIE interface has the advantages of high integration level, small area, low cost and low power consumption.
