Plug & Trust Secure Element

• Symmetric Key (AES, 3DES)

• ECC Key

• RSA Key

• HMAC Key

• Binary File

• User ID

• Counter

• Hash-Extend register

3.1.3 Access control

Each secure object can be linked to object specific access control policies. An access

control policy associates a user identified by an authentication with a set of privileges

such as read, write, …

To scale the functionality into a broad range of ecosystems, a set of different

authentication options is provided:

• User-ID based authentication

• Symmetric key based authentication with secure messaging

• Asymmetric key based authentication with secure messaging

At creation of a secure object, an optional set of policies is associated with that

secure object. Each policy assigns a set of allowed operations on that object to an

authentication object.

3.1.4 Sessions and multi-threading

The SE050 IoT applet is prepared for ecosystems where multi-threading and multi-tenant

use cases are needed on APDU level. To enable that, the applet supports 2 simultaneous

sessions that can span full secure messaging sessions, self-authenticated APDUs for

tenants not requiring long-lasting sessions and on top one default session for single

tenant use cases .

3.1.5 Attestation and trust provisioning

SE050 applet comes with a set of trust provisioned root credentials allowing the owner of

the device to securely attest all generated secure keys. Next to that, a customer has the

possibility to define own attestation keys.

Attestation certificates signed by an attestation CA are included in certain SE050

configurations as documented in [4].

3.1.6 Application support

For specific ecosystems, SE050 IoT applet has built-in crypto features to simplify the

deployment of specific use cases such as

• MIFARE SAM functionality

• Wifi password protection

• ECC-Key and RSA-Key based cloud connectivity

• Secure Sensor readout using I2C controller

• Remote attestation and trust provisioning

• Platform Configuration Registers
