Abstract
The present disclosure relates to system and method for generating a digital signature. comprising computing via a hash function a public key; computing a signature comprising an authentication path traversing the node of at least one binary subtree belonging to a hypertree comprising d layers of binary subtrees each comprising a root node and leaf-nodes; storing the leaf-nodes at the top layer d-1, and those of at least one of the binary subtrees at an intermediate layer d-x, where 2≤x<d; extracting a binary subtree index idx<sub>tree</sub> and inferring if the extracted binary subtree index idx<sub>tree</sub> is associated with at least one binary subtree linked to the stored leaf-nodes at the intermediate layers; choosing an operation mode; generating the digital signature based on the chosen operation mode and on the association of the extracted binary subtree index idx<sub>tree</sub> with a binary subtree linked to the stored leaf-nodes at the intermediate layers.
