ISO/IEC 9798-1:2010规定了使用安全技术的实体认证机制的认证模型、一般要求和约束条件。这些机制被用来证实一个实体就是所声称的实体。待认证实体通过显示其对秘密的了解来证明其身份。这些机制被定义为实体之间的信息交换，以及在需要时与受信任的第三方进行的信息交换。 ISO/IEC 9798后续部分给出了认证交换机制和内容的详细信息。

ISO/IEC 9798-1:2010 specifies an authentication model and general requirements and constraints for entity authentication mechanisms which use security techniques. These mechanisms are used to corroborate that an entity is the one that is claimed. An entity to be authenticated proves its identity by showing its knowledge of a secret. The mechanisms are defined as exchanges of information between entities and, where required, exchanges with a trusted third party. The details of the mechanisms and the contents of the authentication exchanges are given in subsequent parts of ISO/IEC 9798.
