Systems and methods for protecting block cipher computation operations from external monitoring attacks. An example apparatus for implementing a block cipher may comprise a memory device to store instructions for computing a block cipher; and a processing device coupled to the memory device. The processing device performs a Data Encryption Standard (DES) cryptographic operation with multiple rounds of a Feistel structure, each round including a substitution function and a transformation function that combines an expansion function and a permutation function into a single operation. The transformation function transforms a first input portion of an internal state of the respective round and a second input portion of the internal state into a first output portion and a second output portion of data. The second output portion is equal to the first input portion and the first output portion is dependent on a combined permutation output from the transformation function.

A system-on-chip includes a process-voltage-temperature (PVT) sensor with a filter circuit that initiates a patterned digital signal and propagates the patterned digital signal in a manner responsive to variations in semiconductor material, operating supply voltage and operating temperature of the system-on-chip. A digital comparison circuit compares the initiated patterned digital signal and the propagated patterned digital signal. A warning signal is generated in response to the comparison where there is a detection of discrepancy between the initiated patterned digital signal and the propagated patterned digital signal.

A chip with power-glitch detection is provided, which includes a power terminal receiving power, an inverter, and a back-up power storage device coupled to the power terminal. The inverter has an input terminal coupled to the power terminal. The back-up power storage device transforms the power to back-up power. The inverter is powered by the back-up power when a power glitch occurs on the power terminal, and the power glitch is reflected at an output terminal of the inverter.

An event detection controller for a circuit system controlled by a pulse wave modulation signal, can perform a specific event handling when a specific event is detected, wherein the specific event handling includes stopping a pulse wave modulation device, starting up the stopped pulse wave modulation device, controlling the pulse wave modulation device to change the pulse wave modulation signal, outputting a wake-up signal to wake up the circuit system, controlling the pulse detector to change its detection configuration, changing a cumulative occurrences number of the specific pattern of an event discrimination module, outputting a control signal or a first data signal to a peripheral device through a bus connected to an event response module and/or requesting the peripheral device to send a second data signal through the bus.

An apparatus and system for remote attestation of a power delivery network is disclosed. Embodiments of the disclosure enable remote attestation of the power delivery network by storing a trusted golden reference waveform in secure memory. The trusted golden reference waveform characterizes a power delivery network in response to a load generated on the power delivery network. A remote cloud server generates a server-generated remote attestation of the power delivery network by receiving an attestation packet from the power delivery network and verifying whether the attestation packet is consistent with an expected power delivery network identity.

A parameter checking method includes substituting a plurality of initial parameters into a data integrity algorithm to obtain syndrome data using a processor, and using a hardware cipher to calculate a calculation result based on the data integrity algorithm based on a plurality of calculation parameters corresponding to the initial parameters.
