职称英语考试阅读判断试题练习 13.Crypto 密码 Technology is a beauty. We eagerly adopt its pleasure, preferring to cope with the drawbacks on the morning after. Who can resist innovations like mobile phones and networked computers? They put anyone, anywhere, within earshot, and zip information whether an expression of love, a medical chart or a plan for a product rollout around the world in a heartbeat. Unfortunately, its all too easy for eavesdroppers to snap up those messages and conversations en route to their intended receiver. We think were whispering, but were broadcasting. In this case, theres an antidote: cryptography, the use of codes and ciphers to protect information. If you scramble information before its sent, eavesdroppers cant hear what you say or read what youre written. The good news is that, after decades of struggle against a government opposed to its widespread use, weve finally got access to crypto software that does the scrambling, as well as other functions like digital signatures that will authenticate that we are who we say we are in cyberspace. You might not see the crypto, but its there, going into action every time your computer tells you its going into the secret secure mode. What should alarm you is that crypto still isnt therein the millions of medical records, credit-card databases. We can attribute that failure that failure to the governments active opposition. |
