WebThis hash is called the Merkle Root, or the Root Hash. The Merkle Trees are constructed in a bottom-up approach. Every leaf node is a hash of transactional data, and the non-leaf node is a hash of its previous hashes. Merkle trees are in a binary tree, so it requires an even number of leaf nodes. WebJun 24, 2024 · In the proposed CMSS hash tree approach, the key pair generation is achieved first prior to signature generation proposed. The private key is periodically updated after each and every generation of signatures in CMSS. Algorithm 1 presents the steps involved in the key pair generation of the proposed IMHT-OTSS-CSEA Scheme.
