What is RPMC Flash?

What is RPMC Flash?

(RPMC) Replay Protection provides a building block towards providing additional security. This block requires modifications in both a Serial Flash device and Serial Flash Controller. The specification defines new commands for Replay Protected Monotonic Counter operations.

What is replay protected monotonic counter?

The replay protection monotonic counter comprises a first memory block for storing counting data, a second memory block for storing the counting data and an additional memory block for storing an additional identifier; the data of the additional identifier determines the present memory block which is storing the …

What is monotonic counter?

Monotonic counter objects represent hardware counters that exist on the device. Also: >The value of the counter is guaranteed to increase by 1 each time it is read. > The monotonic counter is supported only on soft (non-smart card based) tokens and the value of the counter on each different token is the same.

What is a monotonic transformation?

A monotonic transformation is a way of transforming one set of numbers into another set of numbers in a way that the order of the numbers is preserved.

What is monotonic data?

The term monotonic relationship is a statistical definition that is used to describe a scenario in which the size of one variable increases as the other variables also increases, or where the size of one variable increases as the other variable also decreases.

Is monotonically a real word?

in a monotone; without varying the pitch or expression of one’s voice:A bubbly “So I had the job interview!” conveys one thing, while the same words said monotonically and hesitantly convey the opposite.

How do you know if data is monotonic?

In order to determine how strong of a monotonic relationship exists between the data of two variables and in what direction this relationship is, you need to perform a Spearman Rank-Order Correlation test. If your scatter plot shows your data to look linear and monotonic, you can perform a Pearson’s Correlation test.

Can indifference curves have kinks?

The indifference curves cannot have kinks.

What is the meaning of monotonically?

[ mon-uh-ton-ik-lee ] SHOW IPA. / ˌmɒn əˈtɒn ɪk li / PHONETIC RESPELLING. adverb. in a monotone; without varying the pitch or expression of one’s voice:A bubbly “So I had the job interview!” conveys one thing, while the same words said monotonically and hesitantly convey the opposite.

What are bounded and monotonic sequences?

We will learn that monotonic sequences are sequences which constantly increase or constantly decrease. We also learn that a sequence is bounded above if the sequence has a maximum value, and is bounded below if the sequence has a minimum value. Of course, sequences can be both bounded above and below.

What is unbounded sequence?

If a sequence is not bounded, it is an unbounded sequence. For example, the sequence 1/n is bounded above because 1/n≤1 for all positive integers n. It is also bounded below because 1/n≥0 for all positive integers n.

What is an RPMC flash device?

Flash devices that comply with the RPMC specifications referenced above (“RPMC Flash”) comprise unique control, status and configuration registers and mechanism. RPMC-Flash devices respond to dedicated RPMC instructions.

What does RPMC stand for?

TAICHUNG CITY, Taiwan – 11 October, 2018 — Winbond Electronics Corporation, a leading global supplier of semiconductor memory solutions, today announced the introduction of new SpiFlash® Flash storage components with Replay-Protected Monotonic Counter (RPMC) capability to meet Microsoft and Intel requirements for Windows® 10 Secure UEFI Boot.

How does the non-secure flash respond to RPMC instructions?

In the example embodiment of FIG. 4, the non-secure Flash receives all Flash communication; however, the Flash is configured to respond only to instructions that the Flash supports. For example, if the host issues an RPMC instruction that the non-secure Flash does not support, the non-secure Flash will ignore the instruction.

What is RPMC (replay protected monotonic counter)?

In some embodiments, the identified instruction conforms to a Replay-Protected Monotonic Counter (RPMC) specification, and the processor is configured to execute the identified instruction in accordance with the RPMC specification.
