BitCoin transactions are malleable in a sense that given a transaction an adversary can easily construct an equivalent transaction which has a different hash. This can pose a serious problem in some BitCoin distributed contracts in which changing a transaction’s hash may result in the protocol disruption and a financial loss. The problem mostly concerns protocols, which use a ”refund” transacti...

The problem of the malleability rhenium at room temperature is discussed. It has shown that manufactured by mean electron beam melting able to mechanical treatment rolling temperature. primary condition for minor share tensile stress in processing scheme. suppresses grain boundary sliding a coarse-grained workpiece this refractory HCP-metal.

A biologically inspired neuromolecular architecture implemented on digital circuits is proposed in this paper. Digital machines and biological systems provide different modes of information processing. The former are designed to be effectively programmable, whereas the latter have self-organizing dynamics. Previously, we developed a multilevel computer model that captures intraand interneuronal...

We prove the equivalence of two de nitions of non-malleable encryption appearing in the literature| the original one of Dolev, Dwork and Naor and the later one of Bellare, Desai, Pointcheval and Rogaway. The equivalence relies on a new characterization of non-malleable encryption in terms of the standard notion of indistinguishability of Goldwasser and Micali. We show that non-malleability is e...

For the past twenty years, there has been a continuous evolution in electronic communications equipment. The evolution can be described as one of moving the radio functionality from being located in the hardware platform running with proprietary processors and circuitry to being located in firmware running on programmable logic and then to being located in software running on general purpose pr...

A malleable coding scheme considers not only compression efficiency but also the ease of alteration, thus encouraging some form of recycling of an old compressed version in the formation of a new one. Malleability cost is the difficulty of synchronizing compressed versions, and malleable codes are of particular interest when representing information and modifying the representation are both exp...
