Abstract
In a general aspect, a supersingular isogeny-based cryptography process is performed. In some aspects, a cryptographic element is generated by executing a supersingular isogeny-based cryptography protocol. A generator of a first isogeny kernel is computed. A pre-determined tree topology is traversed. The tree topology includes nodes coupled by edges. A first set of edges represent scalar multiplications, and a second set of edges represent point evaluations. A plurality of isogeny kernels corresponding to respective nodes in the tree topology are computed by executing batches of operations. At least one of the batches includes a first point evaluation represented in the tree topology having a first domain and a first range, and a second point evaluation represented in the tree topology having a second domain and a second range. The first domain, the first range, the second domain and the second range are non-isomorphic elliptic curves.
