摘要:
Techniques for use in sharing a plurality of credential objects of a user account amongst a plurality of mobile devices operative in a wireless network are described. In one illustrative example, a network infrastructure (e.g. a cloud) stores a plurality of encrypted credential objects in association with the user account. Each encrypted credential object is encrypted with a credential key. The network infrastructure also stores a plurality of encrypted forms of the credential key in association with the user account. Each encrypted form of the credential key is encrypted with a respective one of a plurality of device keys. Each device key is stored at respective one of the mobile devices. The network infrastructure provides, to the mobile devices, access to the encrypted credential key and the encrypted credential objects.
