项目标书摘要：量子计算技术已经取得重要进展，对我们现用的公钥密码构成严重威胁。本项目以构建量子计算环境下的公钥密码为目标，采用数学和物理两种技术手段，坚持理论与实践相结合。通过研究将提出基于数据复杂性的密码设计新思想，初步建立量子计算环境下公钥密码的一些基本理论，设计出一种基于数据复杂性的公钥密码安全增强框架和密码算法及一种安全高效的量子公钥密码算法和量子签名算法。利用这一框架可以将现有公钥密码(RSA,ECC,EIGamal)增强为可抵抗量子计算机攻击的公钥密码。并建立模拟验证系统，优化密码框架和算法，模拟量子计算机对ECC密码的攻击，为评估我国二代居民身份证密码安全提供数据依据。.本项目基于数据复杂性设计密码和通过安全增强框架将现有公钥密码增强为可抵抗量子计算机攻击的密码的思想与方法，及研究成果都具有明显的创新性。本申请团队对此已经具有较好的研究基础，可以圆满完成项目。

Application Abstract: Now the technology of quantum computer has been developed rapidly and has threatened the security of public-key cryptosystems used widely in the world.This project targets on designing public-key cryptosystems in quantum computing environment,uses two key techniques of mathematics and physics and combines theory with practice.After researching,the new idea of design public-key cryptosystems besed on data complexity thoery will be proposed,some base theory of designing public-key cryptosystems in quantum computing environment will be established,a type of architecture to strengthen security of public-key cryptosysytem and an algorithm will be proposed,also a type of secre and effective quantu public-key cryptosystem and quantu signature algorithm will be given.Using the architecture to strengthen security of public-key cryptosysytem can convert RSA and ECC and EIGamal into secre public-key cryptosystem in quantum computing environment.Furthermore,this project will build the system of monitor experiment to optimize designed architecture and algorithm of cipher and monitor quantum computer attack to ECC so as to give experiment data for evaluating the security of identification card of China.Not only the new idea of design public-key cryptosystems besed on data complexity thoery and the architecture to strengthen security of public-key cryptosysytem,but also other achievements of this project are innovative.Our team have well base of research and can establish successfully this project.

    • channel state information; frequency modulated carrier wave; humanactivities recognition; wireless sensing applications; Wi-Fi;HEART-RATE-VARIABILITY; SYSTEM

    With the rapid development and wide deployment of wireless technology, Wi-Fi signals have no longer been confined to the Internet as a communication medium. Wi-Fi signals will be modulated again by human actions when propagating indoors, carrying rich human body state information. Therefore, a novel wireless sensing technology is gradually emerging that can realize gesture recognition, human daily activity detection, identification, indoor localization and human body tracking, vital signs detection, imaging, and emotional recognition by extracting effective feature information about human actions from Wi-Fi signals. Researchers mainly use channel state information or frequency modulated carrier wave in their current implementation schemes of wireless sensing technology, called "Walls have eyes", and these schemes cover radio-frequency technology, signal processing technology, and machine learning. These available wireless sensing systems can be used in many applications such as smart home, medical health care, search-and-rescue, security, and with the high precision and passively device-free through-wall detection function. This paper elaborates the research actuality and summarizes each system structure and the basic principles of various wireless sensing applications in detail. Meanwhile, two popular implementation schemes are analyzed. In addition, the future diversely application prospects of wireless sensing systems are presented.
