How relevant are hardware implementations of crypto algorithms?

All of the SHA-3 finalists discussed speed and efficiency of a hardware implementation of their algorithms. How relevant are such details? I'm curious about who commercializes hardware that implements specific hashing algorithms, and who uses them.…

How many computations does it take to figure out the input if you know the function and you know its output to another known function?

I have no background in cryptography so excuse me if this question is a little basic or poorly defined. I'm trying to build a circuit using microcontrollers that implements a hash function of some arbitrary number that a user inputs. I want to make…

When to chose hardware accelerated crypto for Big Data

if you were to recommend a cipher/mode configuration that emphasizes performance for your customers, would you recommend a hardware based accelerated solution over one that isn't? For big data at rest/transit what are some good cipher/mode choices…

Will I be able to (ab)use a FIDO U2F compliant hardware token to decrypt data?

I have heard good things about the emerging "FIDO U2F" standard. I am especially interested in having a JavaScript API for cryptographic functions that I can access through a plug-in in a browser. However, so far all my efforts to obtaining a…

Are FPGAs faster than microcontrollers in cryptography?

So, for my capstone project, I've been working on a cryptographic algorithm accelerator on an FPGA. While it did get approved, I've been suggested to work on a more application-based idea that could incorporate my accelerator, where its use can be…

Why is it that researchers prefer finding secure software solutions over secure hardware solutions?

My understanding is crypto researchers tend to prefer solving a problem in software without the need for secure hardware. Why is this? What is the big problem with using secure hardware if the hardware components are cheap and can be easily made?
