Identification Method of Content Changes of Information Contained Inside Files

Open access


The thesis shows the use of message hash function for integrity attribute change identification in sensitive information asset. Changes introduced to file content may suggest confidentiality attribute violation. It has been verified in what way random changes introduced into file content affect function. The minor number of bytes changed in comparison to file size that was assumed, derives from potential benefits for the attacker. Large number of changes in the file may suggest the situation of encrypting it. Such an action leads to accessibility attribute violation
