A novel detection system is proposed, which employs an optimized deep convolutional neural network learn from opcode sequences. trained multiple times by raw sequences extracted decompiled file, so that feature information can be effectively learned malicious program detected more accurately. More critically, k ‐max pooling method...

With the global promotion and application of 5G technology, data transmitted on network show explosive growth, secure sharing its important is still one research hotspots. Steganography embeds that needs to be shared into digital carrier files transmits it through open channels, which has applications in protecting realizing covert communication. However, encrypted generated by traditional steganography are susceptible compression, cropping, geometric attacks, man-made destruction process...

Covert communication is a crucial technology that hides information in the redundant structure of file and transmission through public channel to achieve secure delivery information. The blockchain network, with characteristics anonymity, decentralization tamper-proofing, can make up for shortcomings multimedia-based covert communication, which include easy exposure identity both parties, vulnerability destruction during weak robustness channel. Therefore, network an ideal communication....

With the development of communication 5G networks and technologies, spectrum resources are increasingly scarce. The scarcity resource makes market-driven auction become an important means allocation, due to complexity network environment, security auctions can not be ignored. Most existing secure schemes introduce a semi-honest agent complete auction. However, hypothetical model does guarantee in actual application scenario, which may lead potential threats: reveal privacy bidders, or...

As an extension of cloud computing, edge computing has attracted the attention academia and industry because its characteristics low latency, high bandwidth, energy consumption.
