The infinite source of random sequences for classified cryptographic systems

Abstract

Assured security is the desirable feature of modern cryptography. A one-time pad cipher may be used to ensure perfect (unconditional) security. There are many ciphers and other cryptographic transformations, which are not perfect, but ensure conditional security adequate to needs. All cryptosystems require keys and other crypto materials. A hardware generator is the best source of random bit sequences used in production of keys for special cryptosystems. Military Communication Institute has developed a generator, which can produce binary random sequences with the potential output rate of 100 Mbit/s. It gives us the capability to build an efficient key generation equipment for cryptosystems rely on the OTP cipher, as well as for cryptosystems based on symmetric or asymmetric transformations, where many of relatively short keys are needed.
