Secure Communication

Secure Communication

When two entities are communicating and do not want a third party to listen in, they need to communicate in a way not susceptible to eavesdropping or interception. This is known as communicating in a secure manner or secure communication. Secure communication includes means by which people can share information with varying degrees of certainty that third parties cannot intercept what was said. Other than spoken face-to-face communication with no possible eavesdropper, it is probably safe to say that no communication is guaranteed secure in this sense, although practical obstacles such as legislation, resources, technical issues (interception and encryption), and the sheer volume of communication serve to limit surveillance.

With many communications taking place over long distance and mediated by technology, and increasing awareness of the importance of interception issues, technology and its compromise are at the heart of this debate. For this reason, this article focusses on communications mediated or intercepted by technology.

Famous quotes containing the word secure:

    We shall make mistakes, but they must never be mistakes which result from faintness of heart or abandonment of moral principles. I remember that my old school master Dr. Peabody said in days that seemed to us then to be secure and untroubled, he said things in life will not always run smoothly, sometimes we will be rising toward the heights and all will seem to reverse itself and start downward. The great thing to remember is that the trend of civilization itself is forever upward.
    Franklin D. Roosevelt (1882–1945)
