In today?s digital age almost all aspects of both federal and commercial day-to-day operations are cyber-based. This heavy reliance on cyber-infrastructure requires security, as without security modern networks are susceptible to both internal and external attacks. This project will result in the advancement of our state of knowledge and our understanding of a number of fundamental cryptographic tasks needed for securing cyber-infrastructure. The efficiency of cryptographic tasks is typically measured in terms of computational load, communication bandwidth needed, and the number of rounds of interaction required. The goals for this research include a study of public key encryption schemes that allow one to encrypt functions of private keys. Another goal is to embark on a broad study of public key encryption schemes with additional algebraic properties that allow combining cyphertexts (without knowing the decryption). Yet another goal of this research effort is to study new techniques for speeding up the computation involved in performing cryptographic tasks. This effort will sponsor new students to join the research program, and it will exercise outreach efforts through education?including education for minority student and security professionals and consultants. Additionally, the results of this project will be integrated into the course curriculum at UCLA at both the graduate and undergraduate levels.

今天上班？在数字时代，几乎所有的联邦和商业日常运作都是基于网络的。这种对网络基础设施的严重依赖需要安全性，因为如果没有安全性，现代网络很容易受到内部和外部攻击。该项目将促进我们的知识水平和我们对保护网络基础设施所需的一些基本加密任务的理解。加密任务的效率通常根据计算负载、所需的通信带宽和所需的交互轮数来衡量。这项研究的目标包括研究公钥加密方案，允许一个加密私钥的功能。 另一个目标是开始对具有额外代数属性的公钥加密方案进行广泛的研究，这些属性允许组合密文（而不知道解密）。这项研究工作的另一个目标是研究新技术，以加快执行加密任务所涉及的计算。这项努力将赞助新的学生加入研究计划，它将行使通过教育推广工作？包括为少数民族学生和安全专业人员及顾问提供教育。此外，该项目的结果将整合到加州大学洛杉矶分校研究生和本科生的课程中。
