  • Publication number: 20180323969
    Abstract: A first 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, second, server. The first server transmits messages between the client device and the second server where the second server has access to a private key that is not available on the first server. The first server receives from the second server a set of session key(s) used in the secure session for encrypting/decrypting communication between the client device and the first server. The session key(s) are generated using a master secret that is generated using a premaster secret generated using Diffie-Hellman public values selected by the client device and the second server. The first server uses the session key(s) to encrypt/decrypt communication with the client device.

  • Patent number: 10033529
    Abstract: 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.

  • Patent number: 10009183
    Abstract: 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.

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.

  • Publication number: 20150341459
    Abstract: 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.

  • Patent number: 8990357
    Abstract: A proxy server receives a request for a web page from a client device. In response to determining that a portion of the web page is available in cache, the proxy server retrieves that portion and transmits it to the client device. The portion of the web page is not the entire web page and is a prediction of the portion of the page that will remain static if the page is reloaded or requested by a different client device. The proxy server transmits a request to an origin server for the full web page. In response to receiving the full web page from the origin server, the proxy server modifies the full web page to remove the portion that was already transmitted to the client device, and transmits the modified web page to the client device.
