Establishing a secure link on a second protocol between a secure element and a smart device via a link on a first protocol by establishing a link on the first protocol between the secure element and the smart device, and generating, by the secure element, a communication encryption key and associating a status with the encryption key and assigning the status a first level. Transmitting the key and the status of the key from the secure element to the smart device over the link on the first protocol. The secure element and the smart device are paired over the second protocol thereby establishing a second-protocol link. Transmitting a message encrypted using the key to the smart device over the second-protocol link. Upon verifying the cardholder as an authorized cardholder for the secure element, elevating the status of the communication encryption key from the first level to a second level.

Secure end-to-end pairing of secure element to mobile device

There is described a method for Java Card application memory footprint optimization which relies on the separation in advance of the code related to the personalization from the rest of the code. It allows this code to perform the personalization of an application installed from a main package while being itself included and installed from a separated package dedicated to the personalization, namely the Card Personalization Specifications (CPS) package. This way, the CPS package and all the code inherent to the personalization can be removed once all the personalization steps have been completed.
