"Witrynais a type of transformation that enlarges or reduces a ﬁgure (called the preimage) to create a new ﬁgure (called the image). The scale factor, r, determines how much bigger or smaller the dilation image will be compared to the preimage.

WitrynaSecond 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 preimage resistance and one-wayness; however, the later concept is typically used for functions with input and output domain of similar size (see one …

WitrynaA second-preimage is also a collision, but we keep the concept distinct because second-preimages are supposed to be substantially harder.
