One of the most efficient methods for cracking passwords, which are hashed based on different cryptographic algorithms, is the one based on “Rainbow Tables”. Those lookup tables offer an almost optimal time-memory tradeoff in the process of recovering the plaintext password from a password hash, generated by a cryptographic hash function. In this paper, the first known such generic system is demonstrated...
In this paper we discuss how one of the most famous local optimization algorithms for the Traveling Salesman Problem, the 2-Opt, can be efficiently implemented in hardware for Euclidean TSP instances up to a few hundred cities. We introduce the notion of "symmetrical 2-Opt moves" which allows us to uncover fine-grain parallelism when executing the specified algorithm. We propose a novel...
In this paper we discuss and analyze the FPGA-based implementation of an algorithm for the traveling salesman problem (TSP), and in particular of 2-Opt, one of the most famous local optimization algorithms, for Euclidean TSP instances up to a few hundred cities. We introduce the notion of "symmetrical 2-Opt moves" which allows us to uncover fine-grain parallelism when executing the specified...
