Method and apparatus for processing a hash tree-based data signature

摘要

The present disclosure relates to a method (30) for processing hash tree-based data signatures. The method (30) is executed in the first device (13, 13a) and receives a data signature generation request from the second device (12, 12a, 12b) (31), wherein the request is generated Including an instruction on the type of storage of the data signature generated, generating a data signature B using a hash tree-based data signature method in response to a data signature generation request (32), and a second device ( 12, 12a, 12b) to provide a reference C to the generated data signature, the generated data signature being obtainable by reference. The present disclosure also relates to a method in a second device, a corresponding device, a computer program and a computer program product. [Selection] Figure 3
