In real life, there is a wide variety of connected devices. Each of them will require its own Trusted Service Manager (TSM). It will be responsible for working with public keys, creating a domain zone for secure calculations, supporting the operation of resource authentication mechanisms and application loading.

the TSM service and the TEE device. It uses various security mechanisms that service point-to-point connections: JSON Web Encryption (JWE), JSON Web Signature (JWS), JSON Web Key (JWK). All of these mechanisms are recommended by one of the main Internet standardization institutions, the IETF Engineering Board.

In order for a connected device to be able to create a secure TEE environment with OTrP support, it must be provided with a pair of unique keys - public and private. These keys act as a basic element of trust. Using them, service providers will be able to allow this device to launch trusted applications (TA).

To summarize, the main elements of OTrP are:

— TSM : is responsible for establishing malta mobile database with a protected device and coordinates access to a trusted code execution environment for the duration of their operation. This is the main element in the operation of the OTrP protocol. Through TSM, domain security management (trusted calculation zone) is provided, and the operation of trusted applications on the device is controlled. With the help of TSM, remote updates for protected applications are initiated.

— Authentication Service (Certificate Authority, CA). This is a mechanism for monitoring mutual trust between the connected device, the TSM service, and the application service based on issued certificates. Each device receives its own set of root certificates, which are called "trust anchors" within the protocol. They are issued by trusted certification authorities, ensuring the validation of a specific instance of the TSM service. They, in turn, check the authenticity of the connected devices, and ensure control over the presence of certificates received from a trusted source.
