In such cases, the certificate must be invalidated to prevent unauthorized access or fraudulent activities. The Android certificate management application plays a vital role in facilitating timely and effective certificate revocation.
-
Integration with Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP)
A key aspect of revocation is the ability of the Android certificate management application to check the revocation status of certificates. This is achieved through integration with CRLs and OCSP responders. CRLs are periodically updated lists of revoked certificates published by Certificate Authorities (CAs). OCSP provides real-time status checks of individual certificates. The application queries these sources to determine if a certificate has been revoked before granting access to a resource. For example, if an employee’s device containing a client certificate used for accessing corporate resources is lost, the certificate can be revoked. The certificate management application, upon checking the CRL or OCSP responder, will deny access to the corporate network, preventing unauthorized access to sensitive data.
-
Automated Revocation Procedures
Android certificate management applications can automate the revocation process when integrated with Mobile Device Management (MDM) systems. When a device is reported lost or stolen, the MDM system can trigger the revocation of any certificates associated with that device.

-
Revocation Propagation and Caching
Effective revocation requires timely propagation of revocation information to all relying parties. Android certificate management applications need to efficiently handle CRL downloads and OCSP responses, including caching mechanisms to minimize latency and bandwidth usage. However, caching must be carefully managed to ensure that revocation information is not stale. The application should periodically refresh the CRLs and OCSP responses to ensure that it has the most up-to-date revocation information. In an e-commerce application, the certificate used to secure customer transactions must be promptly revoked if the private key is compromised. The certificate management application on the customer’s device needs to quickly receive and process this revocation information to prevent fraudulent transactions.
-
User-Initiated Revocation
In some scenarios, users may need to initiate certificate revocation themselves. For example, if a user suspects that their private key has been compromised, they should be able to request revocation through the certificate management application. The application should provide a user-friendly interface for initiating revocation requests and provide clear instructions on the process. After submitting the request, the application should verify the user’s identity and submit the revocation request to the appropriate CA or system administrator. This capability empowers users to take proactive steps to protect their security.
In summary, revocation is a crucial security control, and its effective implementation within an Android certificate management application is paramount. By integrating with CRLs and OCSP, automating revocation procedures, managing revocation propagation and caching, and enabling user-initiated revocation, the application contributes significantly to maintaining a secure mobile environment.
