Linear computational problems emerge from various fields such as engineering and finance. Due to the large scale of these problems, they are often hard to be processed by resource-constrained devices. Thus, outsourcing becomes a natural solution. In this paper, we propose a Secure OutSourcing scheme (LinSOS) for Linear computations. The proposed scheme (LinSOS) is based on affine mapping and imposes...
The rapid adoption of cloud services has propelled network data sharing and storage. Client-side deduplication is proposed to minimize bandwidth and space needed to upload and store duplicated data. The existing solutions, however, were recently found to be vulnerable to attacks that enable the attackers to get full access to the entire file stored on the server after learning just a small piece of...
This paper considers cooperative sensing in cognitive networks under Spectrum Sensing Data Falsification attack (SSDF) in which malicious users can intentionally send false sensing information. One effective method to deal with the SSDF attack is the q-out-of-m scheme, where the sensing decision is based on q sensing reports out of m polled nodes. The major limitation with the q-out-of-m scheme is...
Historically developed for secure communication and military use, CDMA is now serving as one of the most widely used wireless airlink interface and has been identified as a major technique for 3G wireless communications. In addition to the wide bandwidth and low power spectrum density which make CDMA signals robust to narrow band jamming and easy to be concealed within the noise floor, the physical...
