This is because VOC-CP-ABE needs to calculate the hash function and symmetric encryption.
That is, only one example of a hash function was given in the paper, (54) and we had only a weaker version of item (ii) at that time.
A standard BF [5] applies an array of m bits (initially all are set to 0) and k independent hash functions [h.
Figure 3 illustrates the application of hash functions to improve the current SMS-based OTP transaction confirmation procedure.
In this paper, we presented a scheme for the data integrity over the cloud computing and we employ the feature extraction of hand writing signature and Merkle hash function to succeed the integrity principle, in such a way to aid the user to verify and test the data from unauthorized users that employ with the cloud data server.
This protocol doesn't use asymmetric cryptosystem, but only one-way hash functions.
A cryptographic hash function must satisfy additional properties in order to be able to withstand all known types of cryptanalytic attack: 1) Preimage resistance: given a hash value it should be computationally difficult to find any message that has a given hash value.
As can be seen from Table 2, the best time characteristics were obtained by using the MD5 hash function, 65% faster than SHA-2.
This is due to the fact that the stored email-addresses and passwords were hashed using an MD5 hash function in which the encrypted values couldn't be decrypted back to their original format.
1 Principle of the classical HASH function in the authentication process
A keyed-Hash Message Authentication Code (HMAC or KHMAC), is a type of message authentication code (MAC) calculated using a specific algorithm involving a cryptographic hash function in combination with a secret key.
Typical digital signature schemes are constructed by combining a cryptographic hash function and a public key scheme.
