Systems and methods for encoding exchanges with a set of shared ephemeral key data

Abstract:

A method includes generating a shared master secret. The method also includes generating a set of shared ephemeral key data. The set of shared ephemeral key data is generated independent of the shared master secret. A validity duration of the set of shared ephemeral key data is less than a validity duration of the shared master secret. The method further includes encrypting at least one message that is to be transmitted to at least one station based on at least the shared master secret and the set of shared ephemeral key data.

Abstract(Chinese):

一种方法包括生成共享的主密钥。该方法还包括生成一组共享临时密钥数据。共享临时密钥数据集是独立于共享主密钥生成的。共享临时密钥数据集合的有效期短于共享主密钥的有效期。所述方法还包括至少基于所述共享主密钥和所述一组共享临时密钥数据来加密要发送到至少一个站的至少一个消息。
