Abstract: Provided is a method for securely transferring data element values stored in a first device to a second device, where each stored data element value being encrypted with a storage key (KSi). It includes mutually agreeing on a short term session key (STK), determining, for each stored data element value an ephemeral key as a sub-sequence of a pseudorandom sequence (bsi) derived from the short term session key (STK), encrypting, each stored data element values using said ephemeral key, decrypting, each data element value encrypted with an ephemeral key, using the storage key (KSi), to obtain KSi-decrypted data element values, transferring said KSi-decrypted data element values from the first device to the second device, obtaining, by the second device, the ephemeral keys from the short term session key (STK), and decrypting the transferred data element values using the obtained ephemeral key.

Abstract: A mechanism for securing a mobile app for execution on a mobile device. The mechanism includes loading a non-trusted portion of the mobile app from a non-trusted application provider onto the mobile device, operating a key provisioning server to generate keys associated with a trusted execution environment, transmitting the keys associated with the trusted execution environment to the mobile device and to a key directory server, authenticate the mobile device, and upon authenticating the mobile device, transmitting a trusted portion of the mobile app including a trusted application to the mobile device, and installing the trusted portion of the mobile app on the mobile device thereby providing a trusted execution environment. Other systems and methods are disclosed.

Abstract: Method of securing exchanges between two electronic devices, by using an imprint of at least one of the two devices. This imprint is obtained on the basis of all or part of the electronic components of which this device is composed. This imprint will serve, either to protect the confidentiality of the data exchanged, or to attest to the identity of the device issuing the data.
