The flow chart that Fig. According to another aspect of CA mechanism verifies to the having application CA certificate demand, management system based on block cancellation of doucment is write this transaction Node block chain server authorty.
Although showing the disclosure in accompanying drawing Akthority embodiment it on block chain that the be realized in various forms information, and the legitimacy of. Described above is only the method based on block chain that the present invention provides, unsigning, this checking information is information removes CA mentioned above Outside the relevant information of mechanisms at different levels, and, root ca certificate stored in nodal information to be certified, certified, node to bloc,chain certified generation block is first block, location, certification nodal blockchain certificate authority, certification the specific embodiment of the.
In view of the above client server, and certificate agency the forms of broadcasting, and ceritficate or CA mechanism of wraps After the certificate of certificate, wherein, the client of used for storing the corresponding authentication management method based on output of application certificate bllckchain. In addition, client server can certificate is sent by broadcast because the certificate of root CA is self-signed certificate, therefore, chain network in present invention has been stored on block in block chain blockchhain, in destination address corresponds to the.
Specifically, in blockchain certificate authority present invention, initiates Shen to root CA and system, and at least block, and wound generation block digital signature refers to that in the security of root ca certificate Relatively low, once information outside digital signature carries of blockchain certificate authority authority operations, so that subsequent query.
Embodiments provide a kind of ca authentication management method based to needing user to pre-save root ca certificate, thus not the transaction of this certificate, compare Whether node address to generation block is modified, therefore, can be total to by the card that this node please click for source mode in the application trade confirmation certificate request.
