基于可信硬件的智能手机短信加密方案
SMS Encryption Scheme for Smartphones Ba sed on Trusted Hardware
摘要
Abstract
SMS has become a common used method in two-factor authentication,which is widely used for website login, mobile payment, bank transfer and other critical applications .However,many malicious applications take use of mobile operating system vulnerabilities to eavesdrop and intercept SMS for users’ authentication code,which brings a great threat on the security of the us -er’s property.To defend such malicious applications, many SMS encryption applications based on symmetric key encryption algo -rithm or publicp/rivate key system have been started using ,which bring great convenience to the users .However, such solutions cannot guarantee the confidentiality of the SMS plaintext or even the seeds when the mobile OS is compromised .This paper pres-ents TrustSMS(Trusted Short Message Service), a secure SMS encryption scheme by using ARM TrustZone technology .TrustSMS can not only protect the confidentiality of the SMS against a malicious mobile OS, but also guarantee reliable end-to-end SMS transmission.A prototype of TrustSMS is developed on Samsung Exynos 4412.The experimental results show that TrustSMS has small impacts on the mobile OS and its performance overhead is less than 1%.关键词
