One-way Compression Function/the Merkle-damg%C3%A5rd Construction

Famous quotes containing the words compression, function and/or construction:

    The triumphs of peace have been in some proximity to war. Whilst the hand was still familiar with the sword-hilt, whilst the habits of the camp were still visible in the port and complexion of the gentleman, his intellectual power culminated; the compression and tension of these stern conditions is a training for the finest and softest arts, and can rarely be compensated in tranquil times, except by some analogous vigor drawn from occupations as hardy as war.
    Ralph Waldo Emerson (1803–1882)

    Science has fulfilled her function when she has ascertained and enunciated truth.
    Thomas Henry Huxley (1825–95)

    There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.
    John Dewey (1859–1952)
