Study on Trusted Entity in Trusted Cloud Computing Platform

In 2009,foreign researchers had proposed the model of trusted cloud computing platform.This model,however,did not analyze the security of the external trusted entity.Because of the relationship between the model behavior and security of the external trusted entity,if the external trusted entity is threatened,the security of the entire model will be destroyed.After analyzing the threat of an external trusted entity in trusted cloud computing platform,the paper gave a solution to treat this threat which used trust computing technology.
