摘要： A sweep membrane separator includes a membrane that is selectively permeable to a selected gas, the membrane including a retentate side and a permeate side. A mixed gas stream including the selected gas enters the sweep membrane separator and contacts the retentate side of the membrane. At least part of the selected gas separates from the mixed gas stream and passes through the membrane to the permeate side of the membrane. The mixed gas stream, minus the separated gas, exits the sweep membrane separator. A sweep gas at high pressure enters the sweep membrane separator and sweeps the selected gas from the permeate side of the membrane. A mixture of the sweep gas and the selected gas exits the sweep membrane separator at high pressure. The sweep membrane separator thereby separates the selected gas from the gas mixture and pressurizes the selected gas.

摘要： A first aspect of the invention includes a method of securing messages using multiple cryptographic algorithms that distributes the burden of computing a session key using a strong cryptographic algorithm while using the session key with a faster cryptographic algorithm to protect messages long enough to compute a new session key. Some embodiments can be improved by use of a non-repeating seed, slotted storage of session keys, or both. A second aspect of the invention is generally directed to an augmented multi-stage hash function, which can be used as the faster cryptographic algorithm.

摘要翻译： 本发明的第一方面包括使用多个加密算法来保护消息的方法，所述密码算法使用较强密码算法分配计算会话密钥的负担，同时使用具有较快密码算法的会话密钥来保护足够长时间的消息来计算新的会话 键。 一些实施例可以通过使用非重复种子，会话密钥的时隙存储或两者来改进。 本发明的第二方面通常涉及增强的多级散列函数，其可以用作较快的加密算法。
