Method and system for automatic generation of context-aware cover message

A non-transitory storage medium storing instructions which when computer executed by a processor cause the processor to perform a method for facilitating secure communication between a sending device and a receiving device, the method comprising:

• receiving, at the receiving device, a benign message sent over a communication channel from the sending device, wherein the benign message is generated from a topic relevant to a user of the receiving device by the sending device;
• computing a digest from the benign message by hashing the benign message;
• querying a cover message server with the computed digest to determine whether the benign message indicates that an encrypted message is available at a secure message server, wherein the cover message server compares the computed digest of the benign message received from the receiving device with a digest received from the sending device to determine whether the digest computed from the benign message by the receiving device indicates that the benign message is a cover message indicating that the encrypted message is available at the secure message server;
• and
• obtaining the encrypted message from the secure message server, in response to determining that the benign message indicates that the encrypted message is available at the secure message server.

A computing system for facilitating secure communication between a sending device and a receiving device, comprising:

• a computer processor;
• and
• a storage device coupled to the processor and storing instructions which when executed by the processor configures the processor to:
• receive, at the receiving device, a benign message sent over a communication channel from the sending device, wherein the benign message is generated from a topic relevant to a user of the receiving device by the sending device;
• compute a digest from the benign message by hashing the benign message;
• query a cover message server with the computed digest to determine whether the benign message indicates that an encrypted message is available at a secure message server, wherein the cover message server compares the computed digest of the benign message received from the receiving device with a digest received from the sending device to determine whether the digest computed from the benign message by the receiving device indicates that the benign message is a cover message indicating that the encrypted message is available at the secure message server;
• and
• obtain the encrypted message from the secure message server, in response to determining that the benign message indicates that the encrypted message is available at the secure message server.
