Signature verification method, memory storage device and memory control circuit unit

The invention provides a signature verification method, a memory storage device and a memory control circuit unit. The method comprises the following steps: reading first data, signature information and first verification information from a memory storage device; executing a first verification operation according to the signature information and the first verification information; generating second verification information according to the first data; executing a second verification operation according to the first verification information and the second verification information; and executing corresponding processing on the first data according to an operation result of the first verification operation and an operation result of the second verification operation. Therefore, by executing the first verification operation in advance, the verification efficiency of the signature can be improved. 本发明提供一种签名验证方法、存储器存储装置及存储器控制电路单元。所述方法包括：从存储器存储装置中读取第一数据、签名信息及第一验证信息；根据签名信息与第一验证信息执行第一验证操作；根据第一数据产生第二验证信息；根据第一验证信息与第二验证信
