    摘要： A symmetric cryptography for encrypting and decrypting information is provided, that can be implemented efficiently in hardware or in software. The symmetric cryptography uses a key generator, so that the cryptography is not dependent on a single, static cryptography key. The key generator is a value or collection of values from which the key is generated. In some embodiments, the key generator substantially increases the computational complexity of differential cryptanalysis and other cryptographic attacks because it has more entropy than the key(s). In an embodiment, the key generator is updated with one-way functions exhibiting the avalanche effect, which generates an unpredictable sequence of keys used during the encryption or decryption process. In an embodiment, a dynamic key is derived from a key generator with a one-way function. In an embodiment, a block cipher uses a different dynamic key to encrypt each block of plaintext, where each key is derived from a different key generator.

    摘要： The present disclosure includes systems and methods for quorum-based data processing, in which quorum portions are distributed to candidate participants in determined proportions that control groups of required participants. In exemplary embodiments, a server generates a plurality of quorum portions from original data, wherein the original data includes secret information for data processing within a secured computing environment, and wherein at least a predetermined minimum number of the quorum portions are required to reconstruct the original data. Sets of quorum portions are determined from said plurality of quorum portions, wherein each set includes a respective proportion of the plurality of quorum portions, and at least one set includes a larger proportion of the quorum portions. Each set of quorum portions is distributed to a respective one of a plurality of computing devices associated with respective participants over a data network within a secured computing environment.
