DATA INTEGRITY MONITORING IN TRUSTED COMPUTING ENTITY |
摘要 |
A method of security monitoring of data files in a computer platform is carried out by a trusted component having a processor and trusted memory area. The method comprises creating one or a plurality of data files in an untrusted memory area of said computing platform, for each created data file, periodically generating a digest data by applying a hash function to each data file, storing the digest data in a trusted memory area and for each file periodically comparing a current digest data of the file with a previously generated digest data of the file. Any differences between a previous and a current digest data indicate that a file in the untrusted memory area has been corrupted. <IMAGE> |
