An error protection key generation method and system are provided, the method being used to generate a key for use in computing an error protection code for an input data value according to a chosen error protection scheme. The method comprises inputting a plurality of desired data value sizes, and then applying a key generation algorithm to generate a key for use in computing the error protection code for a maximum data value size amongst the plurality of data value sizes. The key generation algorithm is arranged so that it generates the key so as to comprise a plurality of sub-keys, where each sub-key is associated with one of the input data value sizes, and where each sub-key conforms to a key requirement of the error protection scheme. As a result, a generic key is produced containing a plurality of sub-keys, where each sub-key is associated with a particular desired data value size, and can be extracted and used independently given that each sub-key conforms to the error protection scheme requirements. This provides significant benefits in the design and verification of error protection circuits using such keys. |
