IEEE Project Abstract

Internet of Things (IoT) is the internet working of terminal physical devices depend on application programming interfaces (APIs) and sensors to be connected to Internet for collecting and exchanging data. According to the characteristics of IoT, it can provide rich services for terminal user.However, the centralized cloud computing-based storage architecture in IoT faces many challenges such as data security, identity privacy and high latency. To overcome these challenges, this work introduces an IoT network storage architecture based on mobile edge computing (MEC), which not only achieve slow-latency message response and computation offloading of terminal user, but also preserves identity privacy of terminal user. Afterwards, we presented a novel non-interactive pairing-free ID-based proxy resignature scheme (ID-PRS) which is a kernel technique to construct the aforementioned storage architecture.Compared with most of proxy re-signature schemes constructed based on traditional PKI, the proposed scheme avoids expensive pairing operation and intricate certificate-maintenance. And it is demonstrated to be provably secure under the classic security assumptions: integer factoring problem and the RSA assumption. Finally, in contrast to other two ID-PRS schemes, the proposed ID-PRS scheme has more advantages in terms of security, function ability and computation costs. Thus, it is very suitable to be applied to the resource-constrained mobile users.
