Abstract

The invention relates to a method of determining a distance between a first device (200) and a second device (220). In a precomputing phase, both devices (200, 220) compute for a query at a protected query Ma1 and for a response bt a protected response Mb1. In an interactive phase, the first device (200) sends the protected query Ma1 to the second device (220). The second device (220) compares the received protected query Ma1 against the computed protected query Ma1 and sends the protected response Mb1 to the first device (200). The first device (200), compares the received protected response mbt against the computed protected response mbj. The distance is determined based on a measurement of time elapsed between sending the protected query Ma1 to the second device (220) and receiving the protected response Mb1 from the second device (220).
