Abstract
According to one aspect of the invention, a method is disclosed. The method comprises generating an asymmetric cryptographic key pair comprising first and second keys; encrypting a boot loader program for a baseband module with said first key; storing said second key in said baseband module; and distributing said encrypted boot loader program together with said second key.
Claims36
A method comprising:
- generating an asymmetric cryptographic key pair comprising first and second keys;
- encrypting a boot loader program for a baseband module with said first key;
- storing said second key in said baseband module;
- and
- distributing said encrypted boot loader program together with said second key.
2 more elements
A method comprising:
- receiving a radio protocol at a baseband module;
- determining whether said radio protocol has been certified by a certification authority;
- and
- storing said radio protocol in a non-volatile memory device in said baseband module, if said radio protocol has been certified by said certification authority.
1 more element
A method comprising:
- generating an asymmetric cryptographic key pair comprising first and second keys;
- storing said second key in a non-volatile memory device in a baseband module;
- encrypting a radio protocol with said first key, said protocol having been certified by a certification authority;
- and
- distributing said encrypted radio protocol.
2 more elements
Apparatus comprising:
- a receiver to receive a radio protocol;
- a mechanism to determine whether said radio protocol has been certified by a certification authority;
- and
- a non-volatile memory device to store said radio protocol if it has been certified by said certification authority.
1 more element
A computer-readable storage medium having stored thereon a sequence of instructions which when executed cause a processor to perform operations comprising:
- receiving a radio protocol at a baseband module;
- determining whether said radio protocol has been certified by a certification authority;
- and
- storing said radio protocol in a non-volatile memory device in said baseband module, if said radio protocol has been certified by said certification authority.
1 more element
Apparatus comprising:
- means for receiving a radio protocol;
- means for determining whether said radio protocol has been certified by certification authority;
- and
- means for storing said radio protocol if it has been certified by said certification authority in non-volatile memory.
