Abstract

A lightweight solution enables the exchange of multimedia information in a secure manner. Exchanged cryptographic material can be used to encipher multimedia message-oriented communications between devices. This lightweight solution can be used by common off the shelf devices such as smartphones, tablets, feature phones, or special purpose machine to machine devices for private communications, such as command and control, location services, video, audio, electronic attachments, etc. using insecure voice or data communication paths, such as MMS.

Claims

1. In a method for conveying multimedia information to at least one message receiving device through intermediary infrastructure components, comprising:

transforming, using at least a first set of cryptographic material, a first message comprising multimedia information;

encrypting the at least first set of cryptographic material using a second, different set of cryptographic material to generate a second message which includes the encrypted at least first set of cryptographic material as part of the second message, the second message being loosely coupled with the first transformed message; and

encapsulating the first transformed message into a different format within a maximum selected size that will pass through intermediary infrastructure components based on the different format and the maximum selected size being within a message size limit of the intermediary infrastructure components;

a method of receiving and recovering multimedia information comprising;

receiving the encapsulated first transformed message from the intermediary infrastructure components with the at least one message receiving device,

receiving the second message with the at least one message receiving device;

de-encapsulating, with a processor in the at least one message receiving device, the received encapsulated first transformed message from the format that will pass through the intermediary infrastructure components, to recover the first message transformed using the first set of cryptographic material;

decrypting, with the at least one message receiving device, the information in the second message to recover the at least first set of cryptographic material; and

with the at least one message receiving device, using the recovered at least first set of cryptographic material to transform the recovered first message and recover the multimedia information.
