Secure user interface side-channel attack protection

A method for providing a secure user interface on a computing device comprising: receiving, from a user application, a request to utilise a secure user interface on the computing device; obtaining, by a first countermeasure module, first information associated with a security context of the computing device; generating, by the first countermeasure module, a first security assessment based on analysis of the first information; determining, by a security determination module, whether to permit the request to utilise the secure user interface based on the first security assessment; and responsive to a positive determination, enabling access by the user application to the secure user interface.
