Integrated space-air-ground network (SAGIN) has become a key approach to achieve seamless global coverage and efficient information transmission. However, the requirements for task latency and the limited energy supply of unmanned aerial vehicle UAV) pose significant challenges when it acts as edge nodes to provide computation offloading services. To address the computation offloading problem in S...Show More
In order to ensure the security of cloud storage, on the basis of the analysis of cloud storage security requirements, this paper puts forward a kind of hidden mapping hyper-combined public key management scheme based on the hyperelliptic curve crypto system, which is applicable to the distributed cloud storage. A series of operation processes of the key management are elaborated, including key di...Show More
A synchronization algorithm for FBMC is proposed by combination of CAZAC sequence. Using the CAZAC sequence as the pilot symbols, timing synchronization and frequency synchronization of the FBMC system are realized. Considering the effect of fading on the synchronization, the algorithm combining the CAZAC sequence is rational. Computer simulations verify that the estimation error is about 1e-4 und...Show More
