    • In asymmetric cryptography, initially-set public key and private keys are updated as a function of the chosen prime number pair, a host sending an updated public key exponent and a unique prime-pair key associated with the chosen prime number pair to the client, the client using the unique prime-pair key to look-up and retrieve the chosen prime number pair and determine the updated public key and the updated private key as a function of the retrieved chosen prime number pair, the host and the client encrypting and decrypting exchanged messages with the updated public key and the updated private key without executing another handshake. In one aspect, a large even integer is used by host and client to generate a plurality of prime number pairs, and the unique prime-pair key may be a distance between each prime number of an associated prime number pair.
    • 在非对称密码学中,初始设置的公钥和私有密钥根据所选择的素数对进行更新,主机向客户端发送与所选择的素数对相关联的更新的公开密钥指数和唯一的素数对密钥, 客户端使用唯一的素数对密钥来查找和检索所选择的素数对,并根据检索到的所选素数对确定更新的公钥和更新的私钥,主机和客户端加密和解密 使用更新的公钥和更新的私钥交换消息,而不执行另一个握手。 在一个方面,主机和客户端使用大的偶数整数来生成多个素数对,并且唯一的素数对密钥可以是相关联素数对的每个素数之间的距离。

    • A method is provided for obtaining an alloy having an ordered microstructure which comprises the steps of heating the central portion of the alloy under uniform temperature so that it enters a liquid phase while the outer portions remain solid, applying a constant electric current through the alloy during the heating step, and solidifying the liquid central portion of the alloy by subjecting it to a temperature-gradient zone so that cooling occurs in a directional manner and at a given rate of speed while maintaining the application of the constant electric current through the alloy. The method is particularly suitable for use with nickel-based superalloys. The method of the present invention produces an alloy having superior characteristics such as reduced segregation. After subsequent precipitation by heat-treatment, the alloys produced by the present invention will have excellent strength and high-temperature resistance.
