Abstract

The invention provides a method to execute a suitable hybrid signature by a secure element during communication with a reader; the method comprising: - the reader sends to the secure element a command to execute the hybrid signature, - the secure element prompts the reader to fetch parametrized instructions to proceed with the hybrid signature, - the secure element sends a data structure containing pre-configured cryptographic parametrization to perform at least one hybrid signature, - the reader receives the data structure and maps the cryptographic parametrization of the secure element with a set of instructions to cause the secure element to perform the suitable hybrid signature, - the reader sends the set of instructions, and, in response, the secure element sends the result of executing the suitable hybrid signature.
