SIT: A Lightweight Encryption Algorithm for Secure Internet of Things
The Internet of Things (IoT) being a promising technology of the future is expected to connect billions of devices. The increased number of communication is expected to generate mountains of data and the security of data can be a threat. The devices in the architecture are essentially smaller in size and low powered. Conventional encryption algorithms are generally computationally expensive due...
متن کاملRevocable Hierarchical Identity-Based Encryption from Multilinear Maps
In identity-based encryption (IBE) systems, an efficient key delegation method to manage a large number of users and an efficient key revocation method to handle the dynamic credentials of users are needed. Revocable hierarchical IBE (RHIBE) can provide these two methods by organizing the identities of users as a hierarchy and broadcasting an update key for non-revoked users per each time perio...
متن کاملRevocable Hierarchical Identity-Based Encryption with Adaptive Security
Hierarchical identity-based encryption (HIBE) can be extended to revocable HIBE (RHIBE) if a private key of a user can be revoked when the private key is revealed or expired. Previously, many selectively secure RHIBE schemes were proposed, but it is still unsolved problem to construct an adaptively secure RHIBE scheme. In this work, we propose two RHIBE schemes in composite-order bilinear group...
متن کاملRHIBE: Constructing Revocable Hierarchical ID-Based Encryption from HIBE
Up to now, there was very little work on studying the revocation problem in existing hierarchical ID-based encryption (HIBE) systems. Certainly, all existing HIBE systems may inherit the revocation method suggested by Boneh and Franklin to revoke illegal or expired users, in which non-revoked users must periodically update their private keys using secure channels by contacting their ancestors i...
متن کاملA lightweight agent-based architecture for the Internet of Things
We present a lightweight software agent-based architecture for the Internet of Things. The architecture is based on the REST principles and the Internet Drafts by the IETF CoRE Working Group. The software agents describe the state of a computational task, which is then disseminated in message-passing manner in between the participating devices in the system. The computational tasks can be injec...
