METHOD AND DEVICE FOR MANAGING DIGITAL CERTIFICATE
FIG9 is a schematic block diagram of a digital certificate issuing device according to another embodiment of the present disclosure 
Reference is made to FIG9, which is a schematic block diagram of a digital certificate issuing device according to another embodiment of the present disclosure. The digital certificate issuing device includes one or more processors 901 (for example, CPUs), a memory 902 and at least one communication bus 903. The communication bus 903 is configured to connect the one or more processors 901 and the memory 902. The one or more processors 901 are configured to execute an executable module, for example, a computer program, stored in the memory 902. The memory 902 may be a high-speed random access memory (RAM), and may also be a non-volatile memory, for example, at least one disk memory. One or more programs are stored in the memory. The one or more processors 901 are configured to execute instructions stored in the one or more programs, to perform the steps of: negotiating with a digital certificate requesting device by using an authorization code, to establish a security data channel and generate a security key, where the security key includes a data communication key; receiving a digital certificate management request message transmitted from the digital certificate requesting device through the security data channel, where the digital certificate management request message is encrypted with the data communication key; processing the received digital certificate management request message, and generating a digital certificate management response message; and transmitting the digital certificate management response message to the digital certificate requesting device through the security data channel, where the digital certificate management response message is encrypted with the data communication key.

['12. A digital certificate requesting device, comprising: a security data channel establishing unit configured to negotiate with a digital certificate issuing device by using an acquired authorization code, to establish a security data channel and generate a security key, wherein the security key comprises a data communication key; an encrypting unit configured to encrypt a digital certificate management request message with the data communication key; a transmitting unit configured to transmit the digital certificate management request message to the digital certificate issuing device through the security data channel, wherein the digital certificate management request message is encrypted with the data communication key; a receiving unit configured to receive a digital certificate management response message from the digital certificate issuing device through the security data channel, wherein the digital certificate management response message is encrypted with the data communication key; and a processing unit configured to process the digital certificate management response message, to obtain a processing result.', '21. A digital certificate requesting device, comprising: a memory; and one or more programs stored in the memory, wherein the one or more programs comprises instructions which, when executed by one or more processors, cause the one or more processors to perform steps of: negotiating with a digital certificate issuing device by using an acquired authorization code, to establish a security data channel and generate a security key, wherein the security key comprises at least a data communication key; encrypting a digital certificate management request message with the data communication key; transmitting the digital certificate management request message to the digital certificate issuing device through the security data channel, wherein the digital certificate management request message is encrypted with the data communication key; receiving a digital certificate management response message from the digital certificate issuing device through the security data channel, wherein the digital certificate management response message is encrypted with the data communication key; and processing the digital certificate management response message to obtain a processing result.']
