WebApr 10, 2024 · Hash Chain The original purpose of the hash chain is to solve the problem that the encrypted message is easy to steal or be tampered with during transmission. After multiple encryption iterations of the message, the hash chain can effectively resist attacks and interference and can complete verification at the receiving end. WebIn chaining, if a hash function produces the same index for multiple elements, these elements are stored in the same index by using a doubly-linked list. If j is the slot for multiple elements, it contains a pointer to the head of the list of elements. If no element is present, j contains NIL. Collision Resolution using chaining WebJan 6, 2024 · This hash chain in zlib is implemented by using two arrays: prev[] and head[]. Both arrays stores the positions in the sliding window. The head[] array stores the heads of the hash chains, the prev[] array stores and links the positions of strings with the same hash index.
