Abstract
A data processing apparatus is provided that includes storage circuitry. Communication circuitry responds to an access request comprising a requested index with an access response comprising requested data. Coding circuitry performs a coding operation using a current key to: translate the requested index to an encoded index of the storage circuitry at which the requested data is stored or to translate encoded data stored at the requested index of the storage circuitry to the requested data. The current key is based on an execution environment. Update circuitry performs an update, in response to the current key being changed, of: the encoded index of the storage circuitry at which the requested data is stored or the encoded data.
