CRYPTOGRAPHIC SEPARATION OF MMIO ON DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18462605 titled 'CRYPTOGRAPHIC SEPARATION OF MMIO ON DEVICE
Simplified Explanation
The patent application describes technologies for cryptographic separation of MMIO operations with an accelerator device. Here is a simplified explanation of the abstract:
- A computing device with a processor and an accelerator establishes a trusted execution environment.
- The accelerator, based on a target memory address, determines a memory address range for the memory-mapped I/O transaction and generates an authentication tag using a cryptographic key uniquely associated with that range.
- An accelerator validator checks if the generated authentication tag matches the expected tag.
- A memory mapper finalizes the memory-mapped I/O transaction if the authentication tags match.
Potential Applications
This technology can be applied in secure data processing, cryptographic operations, and hardware acceleration.
Problems Solved
1. Ensures secure separation of MMIO operations. 2. Provides a trusted execution environment for cryptographic transactions.
Benefits
1. Enhanced security for memory-mapped I/O transactions. 2. Efficient cryptographic processing with hardware acceleration.
Potential Commercial Applications
"Secure Cryptographic Separation Technology for Accelerator Devices"
Possible Prior Art
There may be prior art related to cryptographic separation of memory operations in hardware devices, but specific examples are not provided in the patent application.
Unanswered Questions
How does this technology impact overall system performance?
The patent application does not delve into the potential performance implications of implementing this cryptographic separation technology. It would be interesting to know if there are any trade-offs in terms of speed or efficiency.
Are there any compatibility issues with existing hardware or software systems?
The patent application does not address whether this technology may face compatibility challenges when integrated into current hardware or software environments. Understanding any potential hurdles in this regard would be important for practical implementation.
Original Abstract Submitted
Technologies for cryptographic separation of MMIO operations with an accelerator device include a computing device having a processor and an accelerator. The processor establishes a trusted execution environment. The accelerator determines, based on a target memory address, a first memory address range associated with the memory-mapped I/O transaction, generates a second authentication tag using a first cryptographic key from a set of cryptographic keys, wherein the first key is uniquely associated with the first memory address range. An accelerator validator determines whether the first authentication tag matches the second authentication tag, and a memory mapper commits the memory-mapped I/O transaction in response to a determination that the first authentication tag matches the second authentication tag. Other embodiments are described and claimed.
