proposed multi-trapdoor hash function that allows multiple entities to compute a trapdoor hash collision with a given hash value .
The proxy removes some data components from the original set for content downscaling and generates trapdoor hash collision that can authenticate the downscaled multimedia data.
The second experiment [Exp.sup.uncheat.sub.A,Sec-DpoS] is identical to [Exp.sup.uncheat.sub.A,Sec-DpoS] except that the adversary encounters a hash collision. Since H is a random oracle, we have
The third experiment [Exp.sup.unforge,3.sub.A,Sec-DpoS] is identical to [Exp.sup.unforge,2.sub.A,Sec-DpoS] except that the adversary encounters a hash collision. Since H is a random oracle, we have
Double hashing is also used to avoid the hash collision
with different set of value position on the test and training samples.
A, C, G, or T), which will dramatically mitigate the possibility of hash collision
However, the use of bit state hashing will reduce the accuracy of the outcome because a state could be mistakenly reported as visited due to a hash collision
and is therefore not stored in the hash array.
While improbable, a hash collision
is a real statistical risk.
Through the analysis of the  and its related code, we found three types of query errors in [KSC17], called losing of partial coefficient error (LPCE), hash collision
error (HCE), and coefficient combination error (CCE), and made some improvements as follows.
This attack is expected to find a hash collision
