In accordance with a first aspect of the present disclosure, a method is conceived for providing a digital representation of a transaction card in a mobile device, comprising: detecting, by a near field communication unit of said mobile device, that the transaction card is in proximity of the mobile device; upon or after said detecting, performing, by a processing unit of said mobile device, the following steps: retrieving the digital representation of the transaction card from a digitization server; loading the digital representation of the transaction card into a memory of the mobile device; activating the digital representation of the transaction card for a predefined validity period; invalidating the digital representation of the transaction card if no successful near field communication transaction has been performed within said validity period. In accordance with other aspects of the present disclosure, a corresponding computer program and a corresponding mobile device are provided.

Method for providing a digital representation of a transaction card in a mobile device

There is disclosed a method for managing content, including generating, by a service provider, an authenticable management script configured to manage content comprised in a secure element; providing, by the service provider, the authenticable management script to the secure element. Furthermore, there is disclosed a method for managing content, comprising: receiving, by a secure element, an authenticable management script for managing content comprised in the secure element; authenticating, by the secure element, the authenticable management script; executing, by the secure element, the management script if the management script is authentic. Furthermore, there are disclosed corresponding computer program products and a corresponding secure element.

Methods for managing content, computer program products and secure element

There is disclosed a method of providing a software update to a secure element comprised in a host device, comprising converting the software update into a sequence of ciphertext blocks using a chained encryption scheme, and transmitting said sequence of ciphertext blocks to the host device. Furthermore, there is disclosed a method of installing a software update on a secure element comprised in a host device, comprising receiving, by the host device, a sequence of ciphertext blocks generated by a method of providing a software update of the kind set forth, converting said sequence of ciphertext blocks into the software update, and installing the software update on the secure element. Furthermore, corresponding computer program products and a corresponding host device are disclosed.

Updating software on a secure element

According to an aspect of the invention, a method for personalizing a secure element for a mobile device is conceived, wherein an application is stored in the secure element and wherein the application is pre-provisioned by loading secure credentials into the application without tying said secure credentials to a specific user of the secure element.

Method for personalizing a secure element, method for enabling a service, secure element and computer program product

Various embodiments relate to a method, device, and non-transitory medium including: determining a master key value for use in secure communications with a different device, wherein the master key value is used as a master key; deriving at least one session key using the master key; generating a new master key value based on the master key; deleting the current master key value; and using the new master key value as the master key.

Efficient key derivation with forward secrecy

A method for managing a secure element which is embedded into a host unit. The described method comprises (a) transmitting a request for a management script from the host unit to a program element of the secure element, (b) at the program element, generating a management script in accordance with the request and encrypting the generated management script, (c) transmitting the encrypted management script from the program element to the host unit, (d) transmitting the encrypted management script from the host unit to a secure domain of the secure element, and (e) at the secure domain, decrypting and executing the management script.

Local trusted service manager

There is described a method for initializing a secure element () for use with a host unit (), the method comprising (a) storing a set of initial keys and a master key in a memory of a secure element (), (b) providing an identifier of a host () unit associated with the secure element, (c) generating a modified set of keys based on the initial set of keys, the master key and the identifier of the host unit, and (d) storing the modified set of keys in the memory of the secure element. There is also described a secure element () adapted for being embedded into a host unit (). Furthermore, there is described a system for initializing a secure element, a computer program and a computer program product.
