What is One Way Hashing — A one-way hash function, also known as a message digest, fingerprint, or compression function, is a mathematical function that takes a variable-length input string and converts it into a fixed-length binary sequence. Furthermore, a one-way hash function is designed in such a way that it is hard to reverse the…

So what is Format Preserved Encryption exactly? — Format-Preserving Encryption (FPE), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). The meaning of “format” varies. FPE encrypts plaintext that is a certain length and produces a ciphertext that is the same length as the plaintext…

INTRODUCTION Most current neural nets experiments use the MultiLayer Perceptrons and the Backpropagation leaming algorithms. Whereas the experimentation speed is insufficient, few analog integrated circuits have been realized for these algorithms, because neither their implementation nor their parallelization is obvious. On the other hand, Boltzmann Machines show a number of very…

In this article, the authors propose a domain-specific FPGA overlay processor, named OPU to accelerate CNN networks. It offers software-like programmability for CNN end users, as CNN algorithms are automatically compiled into executable codes, which are loaded and executed by OPU without reconfiguration of FPGA for switch or update of…
