Message Format Sample Clauses

Message Format. Select one (1) of the following options for TTN Message format.

Message Format. The messages exchanged over the e-Bulk interface will adhere to the XML formats defined and described in [2].

Message Format. Messages must be simple, with a minimum number of words and lines. • PCMS’s shall have no more than two displays (phases) of no more than three lines each with 8 characters per line. If more than two displays (phases) are needed to convey complex messages, then two separate PCMS’s (properly spaced) shall be used and spaced per above guidelines. • Each phase should be displayed for a minimum of 2 seconds and both phases shall be no more than 8 seconds. • Each phase of the PCMS message should attempt to convey an independent and complete informational idea, warning or action to the driver. For example, “FOLLOW DETOUR” should not be separated into two phases. • Use abbreviations only when necessary to convey a complete message. A list of acceptable and unacceptable abbreviations can be found in the attachments or MUTCD Tables 1A-1, 1A-2, and 1A-3. The Temporary Traffic Control (TTC) plan should include the location and messages to be displayed. When changes are needed or for incident management needs, all PCMS orders require the use of the following attached worksheet. The original as well as additional information can be found in the PPM (Volume 1 - Chapter 10).

Message Format. Messaging on the DMS structures should be consistent with the portable PCMS devices. The CEI or other responsible party shall coordinate the displayed messages with the TMC.

Message Format. Modification To prevent replay attacks, Xxxxx et al. use nonces together with informa- tion from the received message, such as sender and receiver identity, sender nonce and received intermediate values, in messages exchanged during the protocol run to guarantee message freshness. While provably secure, this has the unfortunate side effect of noticeably increasing the size of the mes- sage the leader has to transmit in round 3 of the protocol. By using the authentication scheme outlined above, this information is no longer necessary, since the random nonces and MAC keys guarantee message freshness. An attacker wishing to replay an old message together with its corresponding MAC key would still have to correctly guess the next fresh nonce. The probability of his success can then be further decreased by increasing the size of the nonce. It is also possible to use timestampts in messages to provide greater guarantees. Messages with timestamps older than a certain threshold would be automatically discarded not allowing the attacker to replay any mes- sages at all. The final modification to the base Augot protocol is in the init message the leader broadcasts in the first round of the protocol. We instead use the following format: l MSG1 = {0||UL||Ui||n||sizeMAC||Macl}, where 0 denotes the first round of the protocol, UL is the leader’s identity, Ui is the identity the recipient is to assume for the rest of the protocol, n is the total number of members in the group, including the leader, sizeMAC is a two-byte value containing the size of the MAC on the message in num- bers of bytes, and MACl denotes the MAC on the message data in a format as described above. The modified message serves the same purposes as the init message in the original protocol while also allowing us to assign mem- ber positions/identities in the group. Subsequent protocol messages follow the same basic structure, contain- ing the round number, sender and recipient identities, message data size indicator, actual message data, MAC size indicator and the MAC itself. Our implementation of the GDH.3 protocol follows the same structure.

Message Format. Please limit the length of your posts. If you are referring to an article in your message, either quote briefly from it or direct others to where they can read it themselves.
