A method includes: receiving a revocation list from a remote data server at a configuration device. The revocation list includes N cryptographic certificates associated with N computer software entities, respectively, that are not to be executed by any of a group of medical devices including a handheld medical device. N is an integer greater than or equal to zero The method further includes receiving data from the handheld medical device at the configuration device. The data includes a cryptographic certificate that is associated with a given computer software entity that is presently installed in memory of the handheld medical device for execution by the handheld medical device. The method further includes comparing the cryptographic certificate with the revocation list; and selectively executing a protective function by the configuration device when the cryptographic certificate is the same as one of the N cryptographic certificates of the revocation list.
