摘要： Bypass valve assembly that selectively establishes a bypass path for a fluid delivery system and having a body member with a fluid inlet and a bypass fluid outlet, a slidable piston assembly and a slidable cage assembly. Spring members bias the piston assembly and the cage assembly to a closed position to prevent fluid flow from the fluid inlet to the bypass fluid outlet when the delivery pressure is between an upper first threshold pressure value and a lower second threshold pressure value. When the delivery system pressure exceeds the first threshold pressure value, the piston assembly is moved to a first open position that permits fluid flow to the bypass fluid outlet; and when the delivery system pressure is less than the second threshold pressure value, the piston assembly is moved to a second open position to permit fluid flow to the bypass fluid outlet.

摘要： An improved secure communication arrangement separates the tasks of identity verification and certificate issuing, which allows a disassociating of the long-term binding between Alice and her public/private key pair. This is accomplished by a registration authority issuing a password to Alice once it is satisfied of Alice's bona fide. Thereafter, whenever Alice wishes to communicate with Bob, she contacts a certification authority, identifies herself with the password and obtains a private key and a corresponding short-lived certificate. The certificate typically includes Alice's name and a public key in plaintext, and a signature. The signature is derived by hashing the plaintext portion of the certificate to obtain a value, and encrypting the value with the CA's private key. She then contacts Bob, submits her certificate, Bob performs the same hashing function to obtain a value, decrypts the signature with CA's public key to obtain a decrypted value, and compares the value Bob created with the decrypted value. If the two match, Bob is assured that the person submitting the certificate may be communicated with by using the public key included in the certificate.
摘要翻译：改进的安全通信安排分离了身份验证和证书颁发的任务，这允许将Alice与其公钥/私钥对之间的长期绑定分离。这是由注册机构向Alice发出密码完成的，一旦满足爱丽丝的真诚。此后，每当爱丽丝希望与鲍勃沟通时，她都会与认证机构联系，识别自己的密码，并获得私钥和相应的短命的证书。证书通常包括Alice的名称和明文中的公钥，以及签名。签名是通过散列证书的明文部分来获得一个值，并用CA的私钥加密该值来导出的。然后她联系Bob，提交证书，Bob执行相同的哈希函数获取值，用CA的公钥解密签名以获取解密的值，并将Bob创建的值与解密的值进行比较。如果两者匹配，Bob保证提交证书的人可以通过使用证书中包含的公开密钥进行通信。
