Kissel, Introduction to Network Security: Theory and Practice, Wiley [under licence from Higher Education Press], page 113, Firstly, we should change semiprimes from time to time, where a particular semiprime should only be used in a time interval shorter than the time required to factor an RSA challenge number of a similar length. Secondly, we should use semiprimes that consist of more than 200 decimal digits. ==== Synonyms ==== (product of two primes, not necessarily distinct): biprime ==== Derived terms ==== discrete semiprime distinct semiprime ==== Translations ==== === Adjective === semiprime (not comparable) (mathematics) That has properties derived directly or by extension from a semiprime. ==== Derived terms ==== ==== Translations ==== === Further reading === Semiprime ideal on Wikipedia.Wikipedia Semiprime ring on Wikipedia.Wikipedia Semiprime on Wolfram MathWorld
