1. 大的输出空间:•SHA-256 产生一个256位(32字节)的输出,这意味着有2^256种可能的哈希值。这是一个天文数字,使得通过偶然找到两个不同输入产生相同哈希输出的概率极其微小。巨大的输出空间显著降低了意外碰撞的可能性。 2. 雪崩效应:•SHA-256 设计具有强烈的雪崩效应,这意味着即使输入中的一个小变化(例...

collision-resistant hash with a weaker primitive—a target-collision resistant hash function (also known as a universal one-way hash, UOWHF). The signer generates a random keykand outputs the pair (k,σ(k||Hk(M))) as a signature onM. The apparent problem with this approach is the ...

Collision-resistant ids optimized for horizontal scaling and binary search lookup performance. Status: Deprecated due to security. UseCuid2, instead. Note: All monotonically increasing (auto-increment, k-sortable), and timestamp-based ids share the security issues with Cuid. V4 UUIDs and GUIDs ar...

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 ...
