Imparting cryptographic information in network communications

A non-transitory computer readable medium encoding instructions that, when executed by data processing apparatus, cause the data processing apparatus to perform operations comprising:

• receiving a network communication in a client-server environment, the network communication including cryptographic information inserted into a pre-defined portion of the network communication, wherein the pre-defined portion of the network communication is reserved for random data;
• in response to said receiving the network communication, retrieving a first portion of the random data;
• determining a first index into the pre-defined portion of the network communication based on the retrieved first portion of the random data;
• authenticating the network communication using the determined first index;
• in response to said authenticating the network communication, retrieving a second portion of the random data;
• determining a second index into the pre-defined portion of the network communication based on the retrieved second portion of the random data;
• confirming the cryptographic information inserted into the pre-defined portion of the network communication using the determined second index;
• determining that the confirmed cryptographic information specifies that an encrypted session be initiated in the client-server environment;
• and
• in response to said determining that the encrypted session be initiated, initiating the encrypted session using the confirmed cryptographic information.

A system comprising:

• one or more hardware processors;
• and
• a storage system storing instructions that, when executed by the one or more hardware processors, cause the system to perform operations comprising:
• receiving a network communication in a client-server environment, the network communication including cryptographic information inserted into a pre-defined portion of the network communication, wherein the pre-defined portion of the network communication is reserved for random data;
• in response to said receiving the network communication, retrieving a first portion of the random data;
• determining a first index into the pre-defined portion of the network communication based on the retrieved first portion of the random data;
• authenticating the network communication using the determined first index;
• in response to said authenticating the network communication, retrieving a second portion of the random data;
• determining a second index into the pre-defined portion of the network communication based on the retrieved second portion of the random data;
• confirming the cryptographic information inserted into the pre-defined portion of the network communication using the determined second index;
• determining that the confirmed cryptographic information specifies that an encrypted session be initiated in the client-server environment;
• and
• in response to said determining that the encrypted session be initiated, initiating the encrypted session using the confirmed cryptographic information.
