Security of Lightweight Cryptogram Based on the Control Flow Hidden
摘要
Abstract
Compared with the traditional cryptogram ,linghtweight cryptogram has obvious advantages in the hardware or soft‐ware resources demand and operating power consumption etc .Along with the popularization and application of the internet of things , lightweight cipher plays an increasingly important role in the real life ,so new security requirement for lightweight‐cipher‐based sys‐tem is putforward .Lightweight cipher security protection method is based on control flow hidden and oriented to a variety of light‐weight applications ,it exploits the Hcahe's trigger threshold dynamic adjustment and concurrent operation technology of address se‐quence randomization unit to rearrange the address information in the process of program running ,which eliminates the control flow information leakage from the root .Experiments show that control‐flow‐hidden‐based cipher security protection has a good protective effect for all current control‐flow‐hidden‐based attacks analysis method ,and it realizes high level of control flow hidden with minor performance loss ,thus the sensitive data and code within the system are protected .关键词
