What security technology can be used to solve information rejection?
Through digital signature technology, we can solve the security problems of network information such as forgery, denial, counterfeiting and tampering. Digital signature, also known as public key digital signature, is a comprehensive application of asymmetric key encryption technology and message digest technology. It is a number string that can only be generated by the sender of the information and cannot be forged by others. This number string is also an effective proof of the authenticity of the information sent by the sender. Similar to the ordinary physical signature recorded on paper with a pen, it is realized by using the technology in the field of public key encryption and is used to authenticate digital information.
