摘要： Disclosed herein is a method and system for universally encrypting and decrypting a transaction which is a functional unit in a power network, while reducing a system load. When a transmitting node encrypts a transaction, the serial number of the transaction corresponding to each piece of data included in the transaction is present, and data is selected either using a predetermined criterion or randomly, and is then encrypted. The transaction serial number is added to the encrypted data. A receiving node selects data to be decrypted using the transaction serial number or a predetermined criterion. Through this operation, encryption has been conducted from the standpoint of the transaction, but only part of the data is encrypted based on a probability from the standpoint of the data, so that a system load is reduced, thus enabling efficient encryption and decryption technologies to be implemented.
