Authenticators can be constructed by applying a message transmission (MT) authenticator to each of the messages of the input protocol.
In this paper we consider the situation in which the testers can apply a status message: an input that causes the system under test to identify its current state.
In principle, that could apply to a message promoting Nazi ideology in Germany, a critical remark about the monarchy in Thailand, or perhaps even lines from "The Satanic Verses" in India, where the 1988 book remains banned.
If the word, or its stemmed root, is found, we apply a score to the message: Strong, positive = +2 Weak, positive = +1 Weak, negative = −1 Strong, negative = −2 Strong, positive = +2 Weak, positive = +1 Weak, negative = −1 Strong, negative = −2 Because messages can be very different in length, the raw scores are inadequate for comparison.
They are typically run on resource-rich devices and provide centralized message brokers that manage subscription tables and apply a matching algorithm to determine message forwarding.
Filter expressions evaluate to a boolean value when applied to a message.
One is with a so-called one-time pad where a random "key" is applied to a message.
The receiver determines the length of the secret message, then applies a DFT and extract the hidden message from the cover signal.
If the developer does not provide any aggregation function, Radiator applies a simple concatenation of the messages to aggregate.
In [13] a detector for uncoded DF was presented which applies a weighting of the relay messages according to the reliability of the whole source-relay-destination link.
