Claim Text:
1. A computer-implemented method to provide secure services to computing devices comprising secure elements, comprising: maintaining, by a key escrow service computing device, at least one cryptographic key for a secure element of a network computing device, the at least one cryptographic key operable to enable one of a plurality of trusted service managers (“TSMs”) to provide read and write access the secure element via a secure communication channel; receiving, by the key escrow service computing device, a selection of one of the plurality of TSMs, wherein if the secure element comprises information related to a previous TSM that is different from the selected TSM, the key escrow service computing device revokes the at least one cryptographic key from the previous TSM in response to receiving the request to select the TSM; and transmitting, by the key escrow service computing device, the at least one cryptographic key to the selected TSM in response to receiving the selection of the one of the plurality of TSMs to enable the selected TSM to access the secure element using the at least one cryptographic key.
