In this paper, a high-efficient and low-cost secure AMBA framework utilizing the bus data encryption modeling is proposed to resist the probe attacks. By encrypting the confidential data flowing through the bus, the proposed configurable encryption model meets the security requirement of total SoC. Further, a data encryption pipeline with the third-level branch predictor is proposed to accelerate the encryption process. Finally, an SoC with the 32-bit proposed AMBA framework is established and validated with 55nm technology. Experimental results show that the proposed framework achieves 6152Mbps throughput, consumes 39547um2 area, and provides a stronger resistance compared to the other countermeasures.
