  • Compartment - ISO/IEC JTC 1 Information Technology Vocabulary
Universal entry(ies)
06.01.20 (19762)
ISO/IEC standard entry number
DEF

typically sinusoidal wave at a given frequency, but more generally any interrogator waveform suitable for powering a passive tag without amplitude and/or phase modulation cover-coding method by which an interrogator obscures information that it is transmitting to a tag

OBS

To cover-code data or a password, an interrogator first requests a random number from the tag, then performs a bit-wise EXOR of the data or password with the received random number, and, finally, transmits the cover-coded (also called ciphertext) string to the tag; the tag uncovers the data or password by performing a bit-wise EXOR of the received cover-coded string with the original random number.

OBS

continuous wave: term and definition standardized by ISO/IEC [ISO/IEC 19762-4:2008].
