    Abstract: An object stores a signature associated therewith. An authentication method includes generating in the object at least one piece of personalized information of the object based on the stored signature and on at least one indication associated with the object, and communicating without contact by a device to the object during the authentication. The method also includes contactless communications to the device of the at least one piece of personalized information, determining by the device the signature based on at least the one piece of personalized information and on the at least one indication, and verifying the signature by the device.

    Abstract translation: 对象存储与其相关联的签名。 认证方法包括：根据所存储的签名和关于对象的至少一个指示，在对象中生成对象的至少一条个性化信息，以及在认证期间通过设备与对象进行通信。 该方法还包括至少一条个性化信息到设备的非接触式通信，由设备基于至少一条个性化信息和该至少一个指示来确定签名，并且验证该设备的签名 。
