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. The edges of the pre-determined tree topology include a first set of edges representing scalar multiplications and a second set of edges representing point evaluations. A plurality of isogeny kernels corresponding to respective nodes in the tree topology and having a lower order than the first isogeny kernel is computed by executing batches of operations using a plurality of cryptographic co-processors. At least one of the batches includes two or more of the scalar multiplications represented in the tree topology.
