这代表可能存在不同输入但是对应相同输出,只要无法在多项式时间内以不可忽略概率找到即可满足条件。对于h'(x),如果仅仅存在一组碰撞值,对于一个敌手找到这组碰撞的概率依然是1/2^l 是一个可忽略概率,依然满足collision resistant的条件。所以对于这个函数的构造方式,不足以证明不满足是Collision Resistant 却满足 ...
There is a well-known gap between second-preimage resistance and preimage resistance for length-preserving hash functions. This paper introduces a simple concept that fills this gap. One consequence of this concept is that tight reductions can remove interactivity for multi-target length-preserving ...
Quorum of Control + Timelock + No Double Spend + Nonexpiration + Censorship Resistance + Authorization. A multisig 2-of-2 (Quorum) with a timelock (Timelock) used as the "settlement" transaction of a payment channel can be held (Nonexpiration) and spent whenever (Censorship Resistance) by...

Second-preimage resistanceWe propose a new construction for Merkle authentication trees which does not require collision resistant hash functions; in contrast with previous constructions that attempted to avoid the dependency on collision resistance, our technique enjoys provable security assuming the well-...

In this paper, we evaluate the second preimage resistance of the Whirlwind hash function. More precisely, we apply a meet in the middle preimage attack on the compression function which allows us to obtain a 5-round pseudo preimage for a given compression function output with time complexity of...
Our security proofs are extremely simple. We show for instance that the claims of the designers of Haifa regarding second preimage resistance are valid. Lastly, we give arguments that proofs of second preimage resistance by a black-box reduction incur an unavoidable security loss....
Second preimage resistance is the property of a hash function that it is computationally infeasible to find any second input that has the same output as a given input. This property is related to ...doi:10.1007/0-387-23483-7_372B. Preneel...
