Many micropayment 소액결제현금화 structures rely upon cryptographic mechanisms to control credit transfers. The reliability of such systems is of massive significance. Yet maximum business cryptographic systems are much less reliable than one would want. Attacks are continuously said on structures such as satellite tv for pc TV decoders, automatic teller machines, and application meters. Minimizing the danger of such failures is mostly a systems engineering trouble, concerned with careful requirements engineering and thorough checking out. The implementers of micropayment schemes frequently invent their very own cryptography and operational practices from scratch, which regularly fail
