中文摘要: 光学信息安全是一门研究如何将光学信息处理技术应用于信息安全领域的交叉学科,其中,基于双光束干涉理论的信息安全技术的研究是近几年兴起的一个热点,而目前,相关的报道几乎都集中于基于对称/非对称密码体制的图像加密方法的研究,因此,如何在横向和纵向两方面同时推进相关研究的发展成为学者们亟需思考的问题。 在双光束干涉理论的基础上,一方面,本项目将研究基于单向密码体制的图像加密方法,以实现对机密图像完整性的鉴别。同时,拟结合相位恢复技术,设计出一种分级的安全认证方案,以实现对用户身份和访问权限的认证;另一方面,本项目将尝试对基于双光束干涉的加密方案进行科学的安全性评测,揭示其安全隐患,旨在进一步完善相关的密码编码理论和实验技术。本项目拟首次将基于双光束干涉的密码编码技术拓展至单向密码编码和安全认证领域,并对其安全性进行综合评估。本研究无论从光学信息安全理论的完备性还是从实际应用前景来看都具有重要意义。

英文摘要: Optical information security is an interdisciplinary of studying how to apply the optical information processing technology to the field of information security, in which the security technology based on two beams interference has just emerged and drawn a lot of attentions. However, most of the relevant reports are focusing on the symmetric and asymmetric cryptosystem for the image encryption, so it comes to be an emergent problem to promote the theories and techniques based on two beams interference in both horizontal and vertical aspects. On the basis of two beams interference, on the one hand, this project will study the image encryption method based on one-way cryptosystem to identify the integrity of confidential images. Meanwhile, by using of the phase retrieval technique, a hierarchical security certification scheme will be programmed, in order to achieve the identification of the user identity and the access permission; On the other hand, this project will try to evaluate the security strength of the encryption or authentication schemes based on two beams interference and expect to reveal the security risks, the ultimate aim is to further improve the associated encryption theories and experimental techniques.The project intends, to be the first time, to expand the security technology based on the two be
