Key matching method and device, equipment and storage medium

The invention relates to a key matching method and device, equipment and a storage medium. The method comprises the steps that authentication parameters in communication data are acquired, and the authentication parameters comprise a first parameter and a second parameter; performing parallel authentication operation on preset N root keys by using the first parameter to obtain N authentication values; when determining that a target authentication value exists in the N authentication values by using the second parameter, determining a target root key corresponding to the target authentication value; and calculating by using the target root key to obtain an encryption key, wherein the encryption key is used for decrypting encrypted data in the communication data. According to the scheme, the encryption key corresponding to the encrypted communication data can be determined. 本公开涉及一种密钥匹配方法、装置、设备及存储介质。该方法包括，获取通信数据中的鉴权参数，鉴权参数包括第一参数和第二参数；利用第一参数对预设的N个根密钥进行并行鉴权运算，得到N个鉴权值；当利用第二参数确定N个鉴权值中存在目标鉴权值时，确定目标鉴权值对应的目标根密钥；利用目标根密钥
