Abstract

A valid duration period for a digital certificate is established by a process that includes assigning numeric values to certificate term. The numeric value assigned to each certificate term is representative of the valid duration period. The method continues by identifying one certificate term, which may include requesting a user to select a certificate term. The method may include transmitting the requested certificate term to a server. The certificate term requested is sent via a certificate request. The server is configured to convert the numeric value associated with the requested certificate term into a duration counter value. The method may also include a certificate server receiving from the server, the certificate request including the duration counter value. The method may conclude with transmitting the signed certificate request to a client device capable of generating the digital certificate with the requested certificate term.

Claims

1. A method for configuring a valid duration period for a digital certificate having a certificate term, the method comprising:

assigning a numeric value for each certificate term of a plurality of certificate terms, the numeric value being representative of the valid duration period;

identifying a certificate term of the plurality of certificate terms;

converting the numeric value associated with the identified certificate term into a duration counter value according to a local policy defined on a server separately from the identified certificate term;

transmitting a certificate request, including the duration counter value, to a certificate server configured to sign the certificate request in response to receipt thereof;

receiving from the certificate server a signed certificate request; and

transmitting the signed certificate request to a client device capable of generating the digital certificate, the digital certificate having the valid duration period corresponding to the numeric value converted from the identified certificate term being generated on the client device based upon the signed certificate request,

said method performed by a computing system that comprises one or more computing devices.

2. The method of claim 1, wherein identifying the certificate term comprises the server selecting the certificate term by default.

3. The method of claim 1, further comprising:

transmitting, to the client device, data configured to request a user to select the certificate term from the plurality of certificate terms; and

receiving an indication of the certificate term on a server via a certificate request.

4. The method of claim 3, wherein the plurality of certificate terms include a long-term certificate and a short-term certificate.

5. The method of claim 3, wherein the data configured to request a user to select the certificate term from the plurality of certificate terms is one of:

an Active-X component or a .Net component.

6. The method of claim 3, wherein the duration counter value is a computer understood time unit.

7. The method of claim 3, wherein the server is accessible by a server administrator for assigning the numeric value associated with each certificate term of the plurality of certificate terms.

8. The method of claim 6, wherein the signed certificate request comprises a digital signature representing authenticity of the valid duration period corresponding to the duration counter value.

9. Non-transitory computer storage that comprises executable instructions that direct a computing system to at least:

assign a numeric value for each certificate term of a plurality of certificate terms, the numeric value being representative of the valid duration period;

transmit, to a client device, data configured to request a user to identify a certificate term from the plurality of certificate terms;

receive an indication of the identified certificate term via a certificate request,

convert the numeric value associated with the identified certificate term into a duration counter value according to a local policy defined on a server separately from the identified certificate term;

transmit the certificate request including the duration counter value, to a certificate server configured to sign the certificate request in response to receipt thereof;

receive from the certificate server a signed certificate request wherein the signed certificate request comprises a digital signature representing authenticity of the valid duration period corresponding to the duration counter value; and

transmit the signed certificate request to a client device capable of generating a digital certificate, the digital certificate having the valid duration period corresponding to the numeric value converted from the identified certificate term being generated on the client device based upon the signed certificate request.

10. The non-transitory computer storage of claim 9, wherein the duration counter value is a computer understood time unit.

11. The non-transitory computer storage of claim 9, wherein the plurality of certificate terms include a long-term certificate and a short-term certificate.

12. The non-transitory computer storage of claim 9, wherein the data configured to request the user to identify the certificate term from the plurality of certificate terms is based upon automated parameters existing on the client device.

13. A system for configuring a valid duration period for a digital certificate, the system comprising:

a computing system comprising one or more computing devices, said computing system programmed via executable instruction to at least;

assign a numeric value for each certificate term of a plurality of certificate terms, the numeric value being representative of the valid duration period;

transmit component data, to a client device, configured to prompt a user to select a certificate term from the plurality of certificate terms;

receive, from the client device, an indication of a selected certificate term of the plurality of certificate terms;

convert the numeric value associated with the selected certificate term into a duration counter value according to a local policy defined on a server separately from the selected certificate term;

transmit a certificate request including the duration counter value, to a certificate server configured to sign the certificate request in response to receipt thereof;

receive from the certificate server a signed certificate request; and

transmit the signed certificate request to a client device capable of generating a digital certificate, the digital certificate having the valid duration period corresponding to the numeric value converted from the selected certificate term being generated on the client device based upon the signed certificate request.

14. The system of claim 13, wherein the numeric value assigned to each certificate term is variable.

15. The system of claim 13, wherein the plurality of certificate terms include a long-term certificate and a short-term certificate.

16. The system of claim 13, wherein the component data configured to prompt a user to select the certificate term from the plurality of certificate terms is one of:

an Active-X component or a .Net component.

17. The system of claim 13, wherein the duration counter value is a computer understood time unit.

18. The system of claim 13, wherein the server is accessible by a server administrator for assigning the numeric value associated with each certificate term of the plurality of certificate terms.

19. The system of claim 13, wherein the signed certificate request comprises a digital signature representing authenticity of the valid duration period corresponding to the duration counter value.

20. The system of claim 13, wherein the computing system is further programmed via executable instruction to at least, prior to transmitting component data, determine if the user of the client device is authorized to access the server.
