Graphics Processing Units (GPUs) have become a popular choice for general-purpose high-performance computing. Encryption and decryption algorithms such as the Advanced Encryption Standard (AES) have been implemented on GPUs to gain significant speedup. However, the security of the GPU architecture is not well studied, making it potentially risky to offload sensitive computation to GPUs. In this paper,...
Security is the key issue of Mobile Agent system, concerning about host and Mobile Agent itself. This paper analyzes the Mobile Agent_based software framework and its security issues. The current mainstream security technology of the network host supporting Mobile Agent is discussed. A new mechanism of network host security system combination of the latest Internet security research in open platform,...
The paper Puts forward a novel feedback chaotic block cipher algorithm based on external key control. The prominent advantage of the algorithm is that the cipherkey of the system is composed of 128-bit external keys. The system parameters, initial conditions and iterations of the chaotic system generate dynamically in line with the ciphertext feedbacks. In this way, the randomness and complexity of...
