Standard identity-based encryption schemes typically rely on the assumption that secret keys are kept perfectly secure. However, with more and more cryptographic primitives are deployed on insecure devices, key exposure seems inevitable. In this paper, we propose an Identity-based encryption scheme with forward security. In the scheme, secret keys are updated at regular periods of time; furthermore,...
RTEMS uses the heap manager, the partition manager and the region manager to manage memory. A partition is a physically contiguous memory area divided into fixed-size buffers that can be dynamically allocated and deal located. A region provides facilities to dynamically allocate and free memory in variable sized units. RTEMS memory management is insecure because the data structure of managing memory...
In order to optimize signal detection in non-Gaussian environments, the work is addressed to provide realistic modeling of a generic noise probability density. The model depends on few parameters which can be estimated quickly and easily, and so general to be able to describe many kinds of noise such as symmetric or asymmetric. To this end, a new model is introduced, which derives from the generalized...
Independent component analysis (ICA)/blind source separation (BSS) has received many attentions in neural network and signal processing area recent years. In this paper, we consider the data mining problem with ICA. The data model of under-complete ICA in data mining is given and then gives the most popular ICA algorithm-natural gradient algorithm (NGA). Several applications of data mining with ICA...
