Furthermore, the hash value in Step 2 will be a part of the data in node B.
The AuC executes the following functions on the values of the authentication parameters to authenticate the NFC mobile: (1) using all values of IDMnew or IDMold, the AuC performs the H (IDMnew/IDMold [parallel] R1) function to compute the hash value (HIDM) that is equal to the hash value (HIDM) that has been received from the NFC POS; if HIDM is satisfied based on the IDMnew, the corresponding KMnew is retrieved and the flag value F1=1, else if IMD = IDMold, KMold is retrieved and F1=0, else the authentication session is terminated by the AuC; (2) computes R2 value where R2 = IDM [symmetry] M2; (3) executes the XM1 = H (KMnew/KMnew [parallel] R1 [parallel] R2) function to compute the expected hash value XM1; if XM1 = M1 then the NFC mobile is verified, else the AuC terminates the session.
For a block candidate to be accepted by all miners, its fingerprint must possess an extremely rare feature: The hash value must be below a certain threshold value--that is, it must display several zeroes at the beginning of the fingerprint.
Once the function reaches the last pixel in the image, it returns that sum, which is now the image's hash value, just like 100 is the hash value for "Ignatius" in Figure 1 above.
This will give 128 bits one-way hash value which will be used as an authentication watermark for the image.
In detail, the inserted ID is encrypted with the hash value of the PW in the registration process and is decrypted with the hash value of the PW' received from the user in the later authentication process in Step 15.
To overcome this, convergent encryption was proposed, where the hash value of the data is used the encryption key [5].
The main input to the hash function is the message block input and the main output is the digest (or hash value).
The user generates a secret key [K.sub.VM], and encrypts both an initial VM image [alpha] and its hash value #[alpha] with the key.
For each node in the graph, a hash value is produced, which along with the table size produces an index in the table.

The algorithm uses Keccak to compute the hash value of the given DNA sequence as the initial value of the chaotic map, generating a chaotic index of the image position that performs scrambling, which is coupled with a butterfly network to achieve a level of scrambling.
