Abstract
A hardware security block system and method including a security processor unit to perform a security process on a data chunk of at most a predefined size and a memory access unit to transfer the data chunk of at most the predefined size to the security processor unit from an unlimited size data segment in an upper layer. A method and system including receiving a partial data chunk and associated control information, where the partial data chunk is a portion of an unlimited size data segment in an upper layer, determining a security value, and security processing the partial data chunk.
Claims16
A hardware security block comprising:
- a security processor unit to perform a security process on a data chunk of at most a predefined size;
- and
- a memory access unit to transfer the data chunk of at most the predefined size to said security processor unit from an unlimited size data segment in an upper layer.
A system comprising:
- a portable computer comprising:
- a man-machine interface unit;
- a security processor unit to perform a security process on a data chunk of at most a predefined size;
- and
- a memory access unit to transfer the data chunk of at most the predefined size to said security processor unit from an unlimited size data segment in an upper layer.
A method comprising:
- receiving a partial data chunk and control information associated therewith, wherein the partial data chunk is a portion of an unlimited size data segment in an upper layer;
- determining a security value;
- and
- security processing the partial data chunk.
A hardware security method comprising:
- receiving a data chunk of at most a predefined size from an unlimited size data segment in an upper layer;
- and
- security processing in hardware the data chunk of at most a predefined size.
