C  Algorithm test datap. 93

C.1  128-EEA2p. 93

This clause includes six test data sets; all are presented in hex, while the first is also presented in binary. Some intermediate computational values are included to assist implementers in tracing bugs. Some notation is taken from the specification of CTR mode [16].
Bit ordering should be largely self explanatory, but in particular:
  • The 5-bit BEARER is written in hex in a "right aligned" form, i.e. as a two-hex-digit value in the range 00 to 1F inclusive, with BEARER [0] as the msb of the first digit.
  • Similarly the single DIRECTION bit is written in hex in "right aligned" form, i.e. the DIRECTION bit is the lsb of the hex digit.
  • Where the length of plaintext and ciphertext is not a multiple of 32 bits, they are written in hex in a "left aligned" form, i.e. the least significant few bits of the last word will be zero.
