name: TPM
full_form: Trusted Platform Module
context: based authentication on S1 and X2 interfaces in the case of macro eNB. 2) Compromise of H(e)NB authentication token by local physical intrusion Description: An attacker reads authentication credentials from the wires of the H(e)NB and takes a copy. After that, any other device can use it and impersonate the H(e)NB. Probability: Depends on the implementation. If the H(e)NB authentication data is not stored in a protected domain, such as a TPM module or a UICC, the probability of such compromise is high. Otherwise, low. Impact: Harmful. Threats assets are the same as in the previous case. Mitigation: Authentication credentials of the H(e)NB shall be stored inside a secure domain i.e. from which outsider cannot retrieve the credentials. 3) Inserting a valid authentication token into a manipulated H(e)NB. Prerequisites: H(e)NB authenticates to the network with a removable token (e.g. a UICC) or an embedded UICC or TPM that can be physically removed (i.e. case 3 and 4). Description: User
description: A Trusted Platform Module (TPM) is a secure microcontroller designed to provide a secure environment for storing sensitive data, such as authentication credentials, in a network device like an H(e)NB. It acts as a trusted platform for cryptographic operations and secure storage.
explanation: The context describes TPM as a component within a network device (H(e)NB), responsible for secure storage and cryptographic operations. This classification aligns with the definition of a device.
