Abstract
System and method for allowing a mobile telecom device to use multiple profiles. The system and method includes operating a security function to perform a cryptographic operation on a profile using a cryptography key of the security function thereby producing a cryptographically protected profile, storing the cryptographically protected profile, and activating the cryptographically protected profile by operating the security function to verify that the cryptographically protected profile has been cryptographically protected using the cryptography key of the security function, and upon verifying that the cryptographically protected profile has been protected using the cryptography key of the security function, activating the cryptographically protected profile.
