Entry information consists of: value size: 4 bytes, reserved size: 4 bytes, time stamp: 8 bytes, value check sum: 1 byte.
If the CRC sum computed on the decoded bit plane does not match the check sum sent by the encoder, the decoder asks for more parity bits from the encoder buffer.
At present, the integrity of the transmitted data is protected by the already mentioned MD5 check sum and the privacy of the measured data by the use of pseudonyms for the exact measurement points within the grid.
Integrity of key seeds shared among the nodes in RF4CE networks is guaranteed by FCS (Frame Check Sum) initially supported by RF4CE MAC Frame and MIC (Message Integrity Code) provided to packet in Network layer (NWK).
Value size: 0, reserved size: 0, time stamp:0, value check sum: 0. Iterate Other important actions in the key-value store include sequence iterating which is done by scanning each ZDB flat table to iterate all the key-value pairs.
Personal health card numbers recorded in CORR are validated for length and alpha numeric characters and a check sum is computed for each health card number to detect accidental errors that may occur during data entry.
For example, in Figure 3, the broadcast-packet of terminal 3 can not be selected for check-sums and terminals except terminal 2 transmit the relay-packet in the relay phase.
In the indication phase, the destination broadcasts the following knowledge, which costs 2 bits per terminal: the broadcast-packets transmitted in the channel whose |h| is less than R t h = ln m m - l could be selected for check-sums and the terminal whose |h| is larger than T t h = ln m s is permitted to relay the relay-packets, where m is the network size, 0 ≤ s ≤ m and 0 ≤ l ≤ m.
Every bold font numeral represents the terminal whose broadcast-packet is selected to form the check-sum in the relay phase.
In the relay phase, each terminal randomly selects several correctly-decoding packets to form the check-sum (relay-packet), then relays it to the destination.
