Unconditional Security
Information-theoretic security is often used interchangeably with unconditional security. However the latter term can also refer to systems that don't rely on unproven computational hardness assumptions. Today these systems are essentially the same as those that are information-theoretically secure. However it does not always have to be that way. One day RSA might be proved secure, thus becoming unconditionally secure, but it will never be information-theoretically secure.

Famous quotes containing the word security:
“We now in the United States have more security guards for the rich than we have police services for the poor districts. If you’re looking for personal security, far better to move to the suburbs than to pay taxes in New York.”
—John Kenneth Galbraith (b. 1908)
