Abstract
A system comprises signal processing logic that is operably coupled to at least one memory element and is arranged to enable access to the at least one memory element. The signal processing logic is arranged to receive a security key, generate a system key using the received security key and a system specific seed, perform a comparison of the generated system key to a reference key stored in an area of memory of the at least one memory element. The signal processing logic is also arranged to configure a level of access to the at least one memory element based at least partly on the comparison of the generated system key to the reference key stored in memory.
Claims21
A system comprising:
- signal processing logic, the signal processing logic being operably coupled to at least one memory element and arranged to enable access to the at least one memory element;
- wherein the signal processing logic is arranged to receive a security key, generate a system key using the received security key and a system specific seed, perform a comparison of the generated system key to a reference key stored in an area of memory of the at least one memory element, and configure a level of access to the at least one memory element based at least partly on the comparison of the generated system key to the reference key stored in memory.
(canceled)
A method for enabling access to at least one memory element within a signal processing system, the method comprising:
- receiving a security key;
- generating a system key using the received security key and a system specific seed;
- performing a comparison of the generated system key to a reference key stored in an area of memory of the at least one memory element;
- and
- configuring a level of access to the at least one memory element based at least partly on the comparison of the generated system key to the reference key stored in memory.
A computer-readable storage element comprising executable program code for programming signal processing logic, the computer-readable storage element comprising program code for:
- receiving a security key;
- generating a system key using the received security key and a system specific seed;
- performing a comparison of the generated system key to a reference key stored in an area of memory of at least one memory element operably coupled to the signal processing logic;
- and
- configuring a level of access to the at least one memory element based at least partly on the comparison of the generated system key to the reference key stored in memory.
