Cryptographic-related processing is facilitated by obtaining multiple input operands, and packing the multiple input operands together to form a packed integer. The packed integer is an n-bit integer including multiple slots, where input operands of the multiple input operands are packed into every other slot of the multiple slots, and each slot of the multiple slots has a bitwidth k. Further, the process includes providing the packed integer as input to an n-bit accelerator to facilitate performing one or more predefined operations using the packed integer, to transform the packed integer into result data which facilitates cryptographic-related processing.

A system wherein when a normal state is entered: discipline only one of at least three oscillators to an external reference; output frequency and time based on the other oscillators not being disciplined to the external reference; and monitor the output frequency difference of the one of the oscillators being disciplined and a composite value of the output frequency difference among the other oscillators. A spoofing state is identified when the monitored difference is more than a difference threshold. When the spoofing state is identified: reset the frequency and time of the oscillator in the spoofing state to match the composite value of the other oscillators; resume disciplining the oscillator in the spoofing state from the external reference after expiration of a time period; and clear the spoofing state and return to the normal state when the oscillators have the output frequency differences among the oscillators below the difference threshold.

In general, embodiments of the invention relate to implementing a secure boot process in information handling systems that supports both an external root of trust (eRoT) and an internal root of trust (RoT). Further, embodiments of the invention relate to binding a management controller to a specific chassis and, in the case where the eRoT is used, to an eRoT. When the management controller and the chassis are provisioned according to one or more embodiments of the invention, security checks may be performed by management controller executing an initial program loader (IPL) using the aforementioned bindings. If the bindings are not present or do not match, then the boot process halts and the user is unable to use the information handling system.
