Abstract: In accordance with embodiments of the present disclosure, an information handling system may include a host system comprising a host system processor and a device coupled to the host system processor. The information handling system may also include a management controller communicatively coupled to the host system processor and configured to provide management of the information handling system via management traffic communicated between the management controller and a network external to the information handling system and perform runtime verification of a firmware image of the management controller by responsive to each particular read request of the firmware image during runtime of the firmware, verifying integrity of a respective block of the read request and responsive to determining the respective block is corrupted, causing a bootloader of the firmware to, on a subsequent boot of the firmware image, perform recovery of the firmware image.

Abstract: In accordance with embodiments of the present disclosure, a method may include receiving a unique identifier associated with a host information handling system. The method may also include, responsive to receiving the unique identifier, communicating a signed unique identifier to the host information handling system, the signed unique identifier comprising the unique identifier signed with a private key. The method may further include enabling at least one of pre-boot access and root access by a client information handling system to an access controller responsive to the access controller decrypting the signed unique identifier with a public key corresponding to the private key and determining that the decrypted signed unique identifier and the unique identifier match.

Abstract: In accordance with embodiments of the present disclosure, an information handling system may include a processor and an access controller communicatively coupled to the processor. The access controller may include a memory having a bootloader portion including a first memory address and a second memory address a second processor communicatively coupled to the memory. The second processor may be configured to: (i) attempt to execute the a first copy of a bootloader stored at the first memory address; (ii) in the event of a failure to execute the first copy of the bootloader, copy a second copy of the bootloader stored at the second memory address to the first memory address; and (iii) subsequent to copying the second copy to the first memory address, attempt to execute the second copy of the bootloader stored at the first memory address.

Abstract: A system and method is disclosed for programming a field programmable gate array. The system involves the recognition of the next following bit sequence to be transmitted to the FPGA through a general purpose input output device. Once the bit sequence is identified, the data line is only changed at the GPIO in those instances in which the next succeeding data bit in the bit sequences is different from the preceding data bit. In those situations in which the next following bit sequence is not different, the clock line is triggered without the necessity of testing, and changing the logic level of the data line.
