To reduce or eliminate the vulnerability of computer evidence,a secure strategy is designed to protect computer evidence transmitting in network.Firstly,a level module for protecting computer evidence is established,and different secure measures are worked out according to different evidence protection levers.Then,how to protect top-secret evidence is introduced in details.In measures,the sender used advanced encryption standard(AES) to encrypt evidence,secure hash algorithm-1(SHA-1) to compute message digest,digital signature standard(DSS) to produce digital signature with time stamp,and hided compression package of evidence into the image files.The receiver extracted evidence package from the image files,and verified security attributes of evidence.Finally,experiment and security analysis prove the measures can ensure double confidentiality,integrity,authenticity and non-repudiation of computer evidence in network transmission.
