System and method for unified passcode processing

摘要

A system and method for unified password processing is provided. According to an aspect, a device can receive a unified passcode. The unified passcode can be a passcode for unlocking access to the device, or can be the basis for generating additional passwords or both. The unified passcode can also be used for generating additional passcodes for unlocking additional features of the device. The generated passcodes can also be used for unlocking modules that are connected to a device such as a universal integrated circuit card (UICC). In cases where a generated passcode can be used to unlock a UICC, the generated passcode is converted to a personal identification number (PIN). The mobile interface to the UICC can be extended to include alphanumeric passwords, in addition to PINs.

1. A method performed on a communication device, the method comprising:
receiving, by a first module of the communication device, a unified passcode, encoding the unified passcode using a first hash to generate a first encoded passcode, and the first module configured to be unlocked when the first encoded passcode matches a first stored encoded passcode; generating, via the first module, a second encoded passcode at least partially based on a second hash of the unified passcode and based on an offset that is received, the second hash different from the first hash, by encoding the unified passcode using the second hash to generate the second encoded passcode, the second encoded passcode different from the first encoded passcode, the offset based on a difference between the second hash of the unified passcode and a stored reference code associated with a universal integrated circuit card (UICC); and automatically unlocking access, via the second encoded passcode, to the UICC when the second encoded passcode matches a second stored encoded passcode, the UICC connected to the communication device, to allow the communication device to access at least one function of the UICC.
