A pseudonym provides anonymity by protecting the identity of a legitimate user. A user with a pseudonym can interact with an unknown entity and be confident that his/her identity is secret even if the other entity is dishonest. In this work, we present a system that allows users to create pseudonyms from a trusted master public-secret key pair.ududThe proposed system is based on the intractability of factoring and finding square roots of a quadratic residue modulo a composite number, where the composite number is a product of two large primes. Our proposal is different from previously published pseudonym systems, as in addition to standard notion of protecting privacy of an user, our system offers colligation between seemingly independent pseudonyms. This new property when combined with a trusted platform that stores a master secret key is extremely beneficial to an user as it offers a convenient way to generate a large number of pseudonyms using relatively small storage.

机译：笔名通过保护合法用户的身份来提供匿名性。具有化名的用户可以与未知实体进行交互，并且即使另一个实体是不诚实的，也可以确信自己的身份是秘密的。在这项工作中，我们提供了一个系统，该系统允许用户从受信任的主公用密钥对中创建假名。 ud ud提议的系统基于分解的难解性，并找到以二次数为模的二次残差的平方根，其中的复合数是两个大质数的乘积。我们的建议与以前发布的假名系统不同，因为除了保护用户隐私的标准概念外，我们的系统还提供了看似独立的假名之间的搭配。当与存储主密钥的受信任平台结合使用时，此新属性对用户极为有益，因为它提供了使用相对较小的存储来生成大量假名的便捷方法。
