A DSC token, also known as a known digital signature token, is a software or electronic device that contains a user's digital signature. Similar to a physical signature, a digital signature serves as an electronic stamp of authenticity and is specific to each individual or entity. This guarantees that the document or transaction was not altered during transmission and that it came from a legitimate source. By acting as a hardware device for a digital signature certificate, the USB token electronically verifies the identity of the user, thereby strengthening digital security. All Users Must Store Digital Signature Certificates Into USB Tokens Like HYP2003, EPass 2003 Auto, Watchdata Proxy, M Token, Etc. in Compliance With CCA Security Guidelines.
