In the traditional office environment,employees and administrators may lack sufficient security awareness and pay insufficient attention to security issues,which may lead to the problems of data leakage and low security factor of the traditional office log data attribute encryption transmission technology.Therefore,an encryption transmission technology of office log data attributes based on LFM algorithm is proposed.This paper designs the data attribute coding of the office log,uses the LFM algorithm to set the data attribute coding encryption transmission sub key,and realizes the office log data attribute encryption transmission through the encryption transmission of the client and server.By setting the controlled trial,the experimental results show that the safety factor of the proposed office log data attribute encryption transmission technology is more than 0.9,which shows high safety and provides a more reliable safeguard for enterprises'office log data attribute encryption transmission technology.
