The integrity of data stored on a hard disk is typically verified by computing the chained hash value of disk sector data in a specific order. However, this technique fails when one or more sectors turn bad during storage, making it impossible to compute their hash values. This paper presents a k-dimension hashing scheme, which computes and stores multiple(More)
There is an increasing trend for data owners to store their data in a third-party cloud server and buy the service from the cloud server to provide information to other users. To ensure confidentiality, the data is usually encrypted. Therefore, an encrypted data searching scheme with privacy preserving is of paramount importance. Predicate encryption (PE)(More)
Visible light communication (VLC) could provide short-range optical wireless communication together with illumination using LED lighting. However, conventional forward error correction (FEC) codes for reliable communication do not have the features for dimming support and flicker mitigation which are required in VLC for the main functionality of lighting.(More)
