Method and system for protecting logs

The invention relates to a method and a system for protecting logs. A method for protecting confidentiality of an air gap log includes obtaining a data processor key and a driver encryption key during a first log processing cycle, where the data processor key and the driver encryption key are unique to a log driver mounted to at least one computer processor; packaging the driver encryption key with a computer processor key; storing a driver encryption key packaged by the computer processor key in a database, wherein the database is mapped to data that uniquely identifies the log driver; packaging the driver encryption key with a default key known to at least one initiator device; the log driver is emptied; and writing a driver encryption key packaged by the default key to the log driver. Some described methods also include a method of processing a log by an initiator. 本发明涉及保护日志的方法和系统。一种用于保护气隙日志的机密性的方法，包括：在第一日志处理循环期间，获得数据处理器密钥和驱动器加密密钥，其中所述数据处理器密钥和所述驱动器加密密钥对于挂载到至少一个计算机处理器的日志驱动器是唯一的；用计算机处理器密钥包装所述驱动器加密密钥；将由所述计算机处
