摘要： A request for a web page is received at a proxy server. The request originates from a client network application of a client device. The requested web page includes multiple references to multiple images. The proxy server retrieves the requested web page. The proxy server modifies code of the retrieved web page such that the client network application will not, for each one of those images, initially request those images when parsing the page. The proxy server also adds code to the retrieved web page that, when executed by the client network application, causes at least two of the images to be requested with a single request. The proxy server transmits the modified web page to the client device.

摘要： A first server receives a set of cryptographic parameters from a second server. The set of cryptographic parameters is received from the second server as part of a secure session establishment between a client device and the second server. The first server accesses a private key that is not stored on the second server. The first server signs the set of cryptographic parameters using the private key. The first server transmits the signed set of cryptographic parameters to the second server. The first server receives, from the second server, a request to generate a premaster secret using a value generated by the second server that is included in the request and generates the premaster secret. The first server transmits the premaster secret to the second server for use in the secure session establishment between the client device and the second server.

摘要： A server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server. During the handshake procedure, the server receives a premaster secret that has been encrypted using a public key bound with a domain for which the client device is attempting to establish a secure session with. The server transmits the encrypted premaster secret to another server for decryption. The server receives the decrypted premaster secret and continues with the handshake procedure including generating a master secret from the decrypted premaster secret and generating one or more session keys that are used in the secure session for encrypting and decrypting communication between the client device and the server.

摘要： A server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server. During the handshake procedure, the server receives a premaster secret that has been encrypted using a public key bound with a domain for which the client device is attempting to establish a secure session with. The server transmits the encrypted premaster secret to the different server for decryption along with other information necessary to compute a master secret. The different server decrypts the encrypted premaster secret, generates the master secret, and transmits the master secret to the server. The server receives the master secret and continues with the handshake procedure including generating one or more session keys that are used in the secure session for encrypting and decrypting communication between the client device and the server.

摘要： A server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server. During the handshake procedure, the server proxies messages to/from the different server including a set of signed cryptographic parameters signed using the private key on the different server. The different server generates the master secret, and generates and transmits the session keys to the server that are to be used in the secure session for encrypting and decrypting communication between the client device and the server.

摘要： A server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server. During the handshake procedure, the server receives a premaster secret that has been encrypted using a public key bound with a domain for which the client device is attempting to establish a secure session. The server transmits the encrypted premaster secret to the different server for decryption along with other information necessary to compute a master secret and session keys for the secure session. The different server decrypts the encrypted premaster secret, generates the master secret, and generates session keys that are used in the secure session for encrypting and decrypting communication between the client device and the server and transmits those session keys to that server.
摘要翻译： 服务器与客户端设备建立安全会话，其中在建立安全会话时用于握手的私钥被存储在不同的服务器中。 在握手过程中，服务器接收使用与客户端设备尝试建立安全会话的域绑定的公共密钥进行加密的预安全秘密。 服务器将加密的前提密码传送到不同的服务器以进行解密以及计算安全会话的主密钥和会话密钥所需的其他信息。 不同的服务器解密加密的前提秘密，生成主密钥，并生成在安全会话中使用的会话密钥，用于加密和解密客户端设备与服务器之间的通信，并将这些会话密钥发送到该服务器。
