theory of hash function and thoroughly introduced the implementation process and some attacks;furthermore,the extensive applications of hash functions are analyzed.According to the BLS short signatures scheme,a new short proxy signature scheme is proposed in which the hash function has been effectively ...
In this thesis we study how hash chains and other hash structures can be used in various cryptographic applications. In particular we focus on the applications of entity authentication, signatures and key establishment. We study recursive application of hash functions to create hash chains, hash ...
After some recent breaks presented in the technical literature, it has become of paramount importance to gain a deeper understanding of the robustness and weaknesses of cryptographic hash functions. In particular, in the light of the recent attacks to the MD5 hash function, SHA-1 remains currently...
1.proof of membership/proof of including如何证明、即上复杂度为O(log(n)) n:假设这根树有n个数据块 2.proof of non-membership 方法是遍历、复杂度为O(n) 但是可以对叶节点按哈希值进行排序,用二分法对两个相邻的数据块分别向上取哈希直到root hash并验证,复杂度为O(log(n))这种Tree称为sorted merkle ...

The National Institute of Standards and Technology (NIST) has released the final version of its "Secure Hash Algorithm-3" (SHA-3) standard in August 2015. The new standard ("Federal Information Processing Standard (FIPS) 202") specifies four cryptographic hash functions, called SHA3-224, SHA3...
Can node js perform cryptographic functions? . Back to Top ⬆ What Is A Child_process Module In NodeJs? Node.js supports the creation of child processes to help in parallel processing along with the event-driven model. The Child processes always have three streams <child.stdin>, child.stdo...
