TLDR
In this paper, a method for transmitting and receiving a secure message is proposed. But this method is restricted to the first secret values (400) being known only to the originating device and one or more intended recipient devices of the message.Abstract:
A method for transmitting and receiving a secure message. Transmission is by generating, using a device identifier (408), an application identifier (406) and an application value (412), of a message value (502), combining the message value (502) with one or more first secret values (400), said secret values (400) being known substantially only to the originating device and one or more intended recipient devices of the message, to establish a secret message value (506), applying the secret message value (506) and the message to an encoding process (602) to form a secure message block (604), and combining an address (616, 618) with a device identifier (408), the application identifier (406), the application value (412) and the secure message block (604), to form a secure message (606) for transmission which is decodable by the one or more of said intended recipient devices which thereby recover the message, the address, the device identifier, the application identifier and the application value.read more

Method and system for securing communication
TL;DR: In this article, the authors proposed a method for securing communication between a plurality of members, which includes a first member sending a first input to a second member, receiving a second input from the second member and generating, by an n-bit generator, an initial message digest using the first input and the second input.

Randomness Recommendations for Security
TL;DR: The use of pseudo-random processes to generate secret quantities can result in pseudo-security because the sophisticated attacker may find it easier to reproduce the environment that produced the secret quantities than to locate the quantities in the whole of the number space.
