SUP_NEWS Enhanced integrity protection is provided (complying with the B-LT level signature defined by the ETSI standards). Automatic signature verification is performed when you open this document. For signature verification in the Adobe PDF software, please note that: 1. Ensure that the computer is connected to the Internet because Adobe PDF needs to obtain the certificate revocation list (CRL) when verifying the signature. 2. The time required for the Adobe PDF software to verify the signature depends on the network speed of obtaining the Adobe CRL. 3. When you open a document for the first time, it takes some time to verify the signature. If your computer is not connected to the Internet, the signature verification cannot be completed. You can continue to read the document even the verification fails. If you do not need to verify the signature, choose Edit > Preferences > Signatures, click More in the Verification area, and deselect Verify signatures when the document is opened in the Adobe PDF software.
