Detailed Description

E2E Profile11 variant A implementation.

Remarks

The CRC calculation is based on CRC table without any hardware acceleration.

Member Function Documentation

Check()

CheckStatusType ara::com::e2e::Profile11::Check ( const std::vector< uint8_t > &  protectedData )

overridevirtual

Check whether a message is received correctly or not.

Parameters

protectedData

Message payload containing the CRC protection to be checked

Returns

The result of checking the message protection

Remarks

The profile internal state (e.g., counter delta) can be changed after calling the function.

Implements ara::com::e2e::Profile.

TryForward()

bool ara::com::e2e::Profile11::TryForward ( const std::vector< uint8_t > &  unprotectedData, std::vector< uint8_t > &  protectedData  )

overridevirtual

Try to protect a message payload by inserting a CRC header while replicating the E2E status.

Parameters

[in]	unprotectedData	Message payload without any protection
[out]	protectedData	Message payload containing the CRC protection

Returns

True if the protected data is generated successfully; otherwise false

Remarks

The 'protectedData' should be ignored in case of getting 'false' as the return value.

The profile internal state (e.g., counter) can be changed in case of getting 'true' as the return value.
