摘要： A method includes compiling, by a compiler of a Smart Secure Platform (SSP) supporting a Primary Platform and a Secondary Platform, source code comprising an implementation of an operating system of the Secondary Platform and applications of the Secondary Platform, to produce compiled source code compatible by an operating system of the Primary Platform; linking, by the compiler, personalization data to the compiled source code to produce a native Secondary Platform Bundle (SPB) compatible with the Primary Platform, the personalization data being associated with a subscription of a user of the SSP; and delivering, by the compiler, the native SPB.

摘要： A method for transmitting an IP data packet to an IP address associated with a host name is described. A first service message of a Short Message Service is transmitted to a Short Message Service gateway server. The first service message includes a host name resolution request for a host name. A second service message of the Short Message Service is received from the Short Message Service gateway server. The second service message includes an IP address associated with the host name. An IP data packet is transmitted to the IP address associated with the host name.

摘要： The present disclosure relates to a method and device for performing an elliptic curve cryptography computation comprising: twisting, by a first device based on a first index of quadratic or higher order twist (d), a first point (P′KB) on a first elliptic curve over a further elliptic curve twisted with respect to the first elliptic curve to generate a twisted key (PKB); transmitting the twisted key (PKB) to a further device; receiving, from the further device, a return value (ShS) generated based on the twisted key (PKB); and twisting, by the first device based on the first index of quadratic or higher order twist (d), the return value (ShS) over the first elliptic curve to generate a result (ShS′) of the ECC computation.
