- In the current Measured Boot design, BL1, BL2, and BL31, as well as the
- secure world components, form the |SRTM|. Measurement data is currently
- considered an asset to be protected against attack, and this is achieved
- by storing them in the Secure Memory.
- Beyond the measurements stored inside the TCG-compliant Event Log buffer,
- there are no other assets to protect or threats to defend against that
- could compromise |TF-A| execution environment's security.
-
- There are general security assets and threats associated with remote/delegated
- attestation. However, these are outside the |TF-A| security boundary and
- should be dealt with by the appropriate agent in the platform/system.
- Since current Measured Boot design does not use local attestation, there would
- be no further assets to protect(like unsealed keys).
-
- A limitation of the current Measured Boot design is that it is dependent upon
- Secure Boot as implementation of Measured Boot does not extend measurements
- into a discrete |TPM|, where they would be securely stored and protected
- against tampering. This implies that if Secure-Boot is compromised, Measured
- Boot may also be compromised.
-
- Platforms must carefully evaluate the security of the default implementation
- since the |SRTM| includes all secure world components.

+| | |
+| | | Time-of-Check-Time-of-Use (TOCTOU) threats occur |
+| | when the security check is produced before the time |
+| | the resource is accessed. If an attacker is sitting |
+| | in the middle of the off-chip images, they could |

+| | after the integrity and authentication check has |
+| | been performed. |

+| Threat | | **An attacker with physical access can execute |

+| | verification stage using glitching techniques** |
+| | |
+| | | Glitching (Fault injection) attacks attempt to put |
+| | a hardware into a undefined state by manipulating an|
+| | environmental variable such as power supply. |
+| | |
+| | | TF-A relies on a chain of trust that starts with the|
+| | ROTPK, which is the key stored inside the chip and |
+| | the root of all validation processes. If an attacker|
+| | can break this chain of trust, they could execute |
+| | arbitrary code on the device. This could be |
+| | achieved with physical access to the device by |
+| | attacking the normal execution flow of the |
+| | process using glitching techniques that target |
+| | points where the image is validated against the |
+| | signature. |

+
+.. topic:: Measured Boot Threats (or lack of)
+
+ In the current Measured Boot design, BL1, BL2, and BL31, as well as the
+ secure world components, form the |SRTM|. Measurement data is currently
+ considered an asset to be protected against attack, and this is achieved
+ by storing them in the Secure Memory.
+ Beyond the measurements stored inside the TCG-compliant Event Log buffer,
+ there are no other assets to protect or threats to defend against that
+ could compromise |TF-A| execution environment's security.
+
+ There are general security assets and threats associated with remote/delegated
+ attestation. However, these are outside the |TF-A| security boundary and
+ should be dealt with by the appropriate agent in the platform/system.
+ Since current Measured Boot design does not use local attestation, there would
+ be no further assets to protect(like unsealed keys).
+
+ A limitation of the current Measured Boot design is that it is dependent upon
+ Secure Boot as implementation of Measured Boot does not extend measurements
+ into a discrete |TPM|, where they would be securely stored and protected
+ against tampering. This implies that if Secure-Boot is compromised, Measured
+ Boot may also be compromised.
+
+ Platforms must carefully evaluate the security of the default implementation
+ since the |SRTM| includes all secure world components.
