Abstract
A method and system for managing secure information within a portable computing device are disclosed. The portable computing device includes a program module for communicating with a secure element that is part of the portable computing device. The secure element may receive messages utilizing the decrypted crypto keys derived from a non-padded cipher in order to establish a secure communications channel. The secure element may store at least one of a substantial encryption key for server authentication and a substantial encryption key for decrypting encrypted data stored locally within the portable computing device. If an incorrect password is entered after a predetermined number of times, the secure element may activate security measures which may permanently disable the secure element. To establish secure communications between the secure element and a CPU of the portable computing device, a password based encryption algorithm utilizing a non-padded cipher may be employed.
