Is NFC a better option instead of EPC gen-2 in safe medication of inpatients

Abstract

Wrong medication is an important problem of the citizens of many countries. Using contemporary technologies like UHF Gen-2 RFID tags helps decreasing the medication errors, experienced by many. As UHF Gen-2 tags have limited capacity, cryptographic algorithms cannot be accommodated. The only available functions PRNG and CRC cannot be used instead of cryptographic algorithms. To overcome the known weaknesses, various grouping protocols have been proposed. But, each protocol has some deficiencies. Two of those protocols are covered in this study. Some of their common deficiencies are studied and solutions are suggested.
