A mobile device may comprise a secure memory. The mobile device may receive a request from a mobile application executing on the mobile device to store data in the secure memory. The request may comprise the data and a group identifier associated with the mobile application. A primary symmetric key associated with the group identifier may be determined. The data may be encrypted, using the primary symmetric key, to produce first encrypted data. A secondary symmetric key associated with the group identifier may be determined. The first encrypted data may be encrypted, using the secondary symmetric key, to produce second encrypted data. The second encrypted data may be stored to the secure memory.
