作者解决了构建分布式系统时出现的问题，其中存在不完全信任并且需要程序组合。问题是在级联调用时允许对访问控制和记帐进行身份验证。该问题可以被识别为提供级联身份验证之一。作者开发了一种她称之为“护照”的机制，该机制在级联的每个阶段中传递，并在每次转换时进行数字签名。这样签名的信息对于身份验证至关重要。重点是认识到问题并设计出足够有效且可用的解决方案，尽管这种机制会产生一些成本。<<ETX>>
The author addresses a problem that has arisen in building distributed systems in which incomplete trust exists and program composition is necessary. The problem is to permit authentication for both access control and accounting when cascading invocations. The problem can be identified as one of providing cascaded authentication. The author has developed a mechanism she calls passports that are passed along with each stage of the cascade and digitally signed at each transition. The information thus signed is that which is critical to the authentication. The focus is both on recognizing the problem and on devising a solution that is efficient enough to be usable, although there will be some cost associated with such a mechanism.<<ETX>>
