Authorization method and system

The invention discloses an authorization method and system. The method comprises the following steps: setting an external authentication secret key in a signature Key and an authorization Key, wherein the external authentication secret key is in one-to-one relationship with a serial number of the signature Key; the authorization Key sends an encrypted public key to the signature Key through a first computer to save; after receiving an identity authentication request, a second computer obtains a second random number and the serial number from the signature Key and sends the same to the authorization Key; the authorization Key searches the external authentication secret key by using the serial number, and uses the external authentication secret key and an encrypted private key to sign the second random number to generate to-be-verified data to send to the signature Key through the second computer; and the signature Key verifies the received to-be-verified data by using the encrypted public key and the external authentication secret key. The method provided by the invention realize the one-to-one or one-to-many relevance of the authorization Key and the signature Key, after the identity is authenticated, the signature Key and the authorization Key can sign the data of each transaction so as to guarantee the authenticity and validity of the transaction between bank and enterprise.

Graphene material based disperse and quick solid-phase extraction method

The invention relates to a graphene material based disperse and quick solid-phase extraction method. The graphene material based disperse and quick solid-phase extraction method comprises the steps of performing pore forming and activation on a graphene material to obtain an activated graphene material, wherein the graphene material is graphene or modified graphene; adding the activated graphene material into a chemical sample to be processed to obtain a mixture, shaking and extracting the mixture, then performing centrifugation to obtain a precipitate and supernate, wherein the supernate contains a target component to be detected. The grid cross-linking degree of the activated graphene material is improved, and the graphene material is easily separated in the centrifugal or filtered operation. By means of the method, a disperse solid-phase extraction technology and the activated graphene material serving as a solid-phase extraction solution can be combined, and a complicated operation in traditional solid-phase extraction is simplified and is simple. Impurities can be selectively absorbed by the activated graphene material, and accordingly impurity removal is effectively performed on chemical samples. Therefore, the method is good in separation effect.
