Abstract:
A portable communication device may include a mobile application executing in an application execution environment and a secure application executing in a trusted execution environment. The secure application may receive, from the mobile application, a storage request to store sensitive data. The storage request may include an encrypted data type identifier and an encrypted sensitive data. The secure application may decrypt the encrypted data type identifier and the encrypted sensitive data using a transport key, and re-encrypt the sensitive data using a storage key. The re-encrypted sensitive data can then be stored in a memory of the portable communication device which is outside the trusted execution environment.

Claim (Index 30):
A method for managing sensitive data in a portable communication device having a mobile application executing in an application execution environment and a secure application executing in a trusted execution environment, the method comprising:\n receiving, by the secure application from a mobile application executing in an application execution environment of the portable communication device, a first storage request to store first sensitive data, the first sensitive data being a token or a cryptogram generation key, the first storage request including a first encrypted data type identifier and first encrypted sensitive data; decrypting, by the secure application, the first encrypted data type identifier and the first encrypted sensitive data using a transport key; determining, by the secure application, whether the first decrypted data type identifier indicates that the first sensitive data is a token or a cryptogram generation key; re-encrypting, by the secure application based on the first decrypted data type identifier, the first sensitive data using a key to generate re-encrypted first sensitive data; and storing the re-encrypted first sensitive data outside the trusted execution environment.
