This can indicate a communication failure between the application and an external cryptoprocessor or between the cryptoprocessor and an external volatile or persistent memory. A communication failure may be transient or permanent depending on the cause.

Warning

If a function returns this error, it is undetermined whether the requested action has completed or not. Implementations should return PSA_SUCCESS on successful completion whenever possible, however functions may return PSA_ERROR_COMMUNICATION_FAILURE if the requested action was completed successfully in an external cryptoprocessor but there was a breakdown of communication before the cryptoprocessor could report the status to the application.

A tampering attempt was detected.

If an application receives this error code, there is no guarantee that previously accessed or computed data was correct and remains confidential. Applications should not perform any security function and should enter a safe failure state.

Implementations may return this error code if they detect an invalid state that cannot happen during normal operation and that indicates that the implementation's security guarantees no longer hold. Depending on the implementation architecture and on its security and safety goals, the implementation may forcibly terminate the application.

This error code is intended as a last resort when a security breach is detected and it is unsure whether the keystore data is still protected. Implementations shall only return this error code to report an alarm from a tampering detector, to indicate that the confidentiality of stored data can no longer be guaranteed, or to indicate that the integrity of previously returned data is now considered compromised. Implementations shall not use this error code to indicate a hardware failure that merely makes it impossible to perform the requested operation (use PSA_ERROR_COMMUNICATION_FAILURE, PSA_ERROR_STORAGE_FAILURE, PSA_ERROR_HARDWARE_FAILURE, PSA_ERROR_INSUFFICIENT_ENTROPY or other applicable error code instead).

This error indicates an attack against the application. Implementations shall not return this error code as a consequence of the behavior of the application itself.

Stored data has been corrupted.

This error indicates that some persistent storage has suffered corruption. It does not indicate the following situations, which have specific error codes:

• A corruption of volatile memory - use PSA_ERROR_CORRUPTION_DETECTED.
• A communication error between the cryptoprocessor and its external storage - use PSA_ERROR_COMMUNICATION_FAILURE.
• When the storage is in a valid state but is full - use PSA_ERROR_INSUFFICIENT_STORAGE.
• When the storage fails for other reasons - use PSA_ERROR_STORAGE_FAILURE.
• When the stored data is not valid - use PSA_ERROR_DATA_INVALID.

Note

A storage corruption does not indicate that any data that was previously read is invalid. However this previously read data might no longer be readable from storage.

When a storage failure occurs, it is no longer possible to ensure the global integrity of the keystore.

Definition at line 289 of file TARGET_TFM/TARGET_TFM_LATEST/include/psa/crypto_values.h.

Data read from storage is not valid for the implementation.

This error indicates that some data read from storage does not have a valid format. It does not indicate the following situations, which have specific error codes:

• When the storage or stored data is corrupted - use PSA_ERROR_DATA_CORRUPT
• When the storage fails for other reasons - use PSA_ERROR_STORAGE_FAILURE
• An invalid argument to the API - use PSA_ERROR_INVALID_ARGUMENT

This error is typically a result of either storage corruption on a cleartext storage backend, or an attempt to read data that was written by an incompatible version of the library.

There is not enough entropy to generate random data needed for the requested action.

This error indicates a failure of a hardware random generator. Application writers should note that this error can be returned not only by functions whose purpose is to generate random data, such as key, IV or nonce generation, but also by functions that execute an algorithm with a randomized result, as well as functions that use randomization of intermediate computations as a countermeasure to certain attacks.

Implementations should avoid returning this error after psa_crypto_init() has succeeded. Implementations should generate sufficient entropy during initialization and subsequently use a cryptographically secure pseudorandom generator (PRNG). However implementations may return this error at any time if a policy requires the PRNG to be reseeded during normal operation.

The decrypted padding is incorrect.

Warning

In some protocols, when decrypting data, it is essential that the behavior of the application does not depend on whether the padding is correct, down to precise timing. Applications should prefer protocols that use authenticated encryption rather than plain encryption. If the application must perform a decryption of unauthenticated data, the application writer should take care not to reveal whether the padding is invalid.

Implementations should strive to make valid and invalid padding as close as possible to indistinguishable to an external observer. In particular, the timing of a decryption operation should not depend on the validity of the padding.

There was a storage failure that may have led to data loss.

This error indicates that some persistent storage is corrupted. It should not be used for a corruption of volatile memory (use PSA_ERROR_CORRUPTION_DETECTED), for a communication error between the cryptoprocessor and its external storage (use PSA_ERROR_COMMUNICATION_FAILURE), or when the storage is in a valid state but is full (use PSA_ERROR_INSUFFICIENT_STORAGE).

Note that a storage failure does not indicate that any data that was previously read is invalid. However this previously read data may no longer be readable from storage.

When a storage failure occurs, it is no longer possible to ensure the global integrity of the keystore. Depending on the global integrity guarantees offered by the implementation, access to other data may or may not fail even if the data is still readable but its integrity cannot be guaranteed.

Implementations should only use this error code to report a permanent storage corruption. However application writers should keep in mind that transient errors while reading the storage may be reported using this error code.
