Investigations Into New Public Key Systems

公钥加密技术是当今电子商务的主流技术和重要工具。为了超越机密性和身份验证的基本安全服务，现在需要额外的特性，例如加密的可验证性、分布式密钥生成以及面向组的加密和签名。与此同时，移动业务需求的不断增长要求公钥实现的计算和存储需求最小。该项目将研究最近提出的五种公钥算法，并评估它们在各种安全应用中的适用性。这些结果在澳大利亚的电子商务市场具有重要的潜在价值。

Public key cryptography is now mainstream technology and an essential tool in electronic business. In order to go beyond the basic security services of confidentiality and authentication, additional features are now desirable, such as verifiability of encryption, distributed key generation, and group-oriented encryption and signatures. At the same time the increasing demand for mobile business requires public key implementations with minimal computational and storage demands. This project will study five recently proposed public key algorithms and assess their suitability for various secure applications. These results are of significant potential value in Australia's electronic commerce market.
