Yet most commercial cryptographic systems are less reliable than one would wish. Attacks are continuously reported on systems such as satellite TV decoders, automatic teller machines, and utility meters. Minimizing the risk of such failures is primarily a systems engineering issue, concerned with careful requirements engineering and thorough testing. The implementers of 휴대폰결제현금화 schemes often invent their own cryptography and operational practices from scratch, which often fail.
