    Design and implementation of hardware-based dynamic instruction set randomization framework by San DU, Hui SHU, Fei KANG

    Published 2017-11-01
    “…All the existing ISR methods have some defects including stripping data from code segment is hard to accomplish,static ISR has fixed key and pseudo-random key is not secure.To introduce ISR technology into the se-curity protection of kernel layer and application layer,hardware-based dynamic instruction set randomization framework (HDISR) was designed and implemented,in which program code was encrypted at loading time.Kernel encryption uses kernel key and applications encryption uses a different user key per process.The experimental re-sults show that HDISR can degrade code injection attack to Denial of Service attack with less than 2.57% additional hardware and 0.31s startup delay of each megabyte code encryption.…”

    LAA system dynamic sub-frame configuration strategy in unlicensed bands by Wei JIANG, Shixiao LIU, Heng HU, Chenlu ZHANG

    Published 2016-07-01
    “…The use of dynamic TDD technology in heterogeneous network can effectively increase the system throughput and improve the performance of the system.Due to the limitation of signaling control and other issues,there is usually a dynamic switching between the traditional seven fixed sub-frame ratios in the licensed bands.But as a complement to the LTE system worked in the licensed bands,the unlicensed bands can achieve a more flexible and complete dynamic sub-frame configuration without considering signaling control and other issues.Two new dynamic sub-frame configuration algorithms in unlicensed bands were proposed and compared with traditional static sub-frame configuration,then the impact of dynamic sub-frame allocation algorithms on system performance was verified by LAA system level simulation platform.The results show that the proposed dynamic sub-frame configuration strategies can effectively improve the resource utilization and the overall system throughput.…”
