Abstract
Generation process disturbs the internal state. It is very difficult to predict or model to produce the output. Unpredictable random produces a stream of zeros and ones that divided into sub streams or blocks of random numbers. The need of randomness arises in many cryptographic applications. For example, keys are generated in a random fashion in a common cryptosystems. Many cryptographic. If the random number generation and the processes surrounding it are weak, then the key can easily be copied, forged or guessed and the security of the entire system is compromised. Therefore, high-quality key generation that ensures unpredictable, random keys is critical for security. Applications that generate key get the randomness from the operating system.The operating system, in turn, gets the randomness where it can find it. Ideally the OS gets randomness from a proper hardware generator, which is present in modern PC and smartphone processors. Easy-to-guess values) as the seed for its pseudo-random num-ber generator. This bug caused affected machines to select a 1024-bit RSA modulus from a pool of fewer than one million values, rather than the near-21000 possible values 45. By replaying the key generation process using each of the one. Pseudo-random number generator for key generation. Two Berkeley graduate students reverseengineered the code of the browser and revealed a serious - security flaw. They noticed that the seed used by the pseudo -random number generator depended on the time of the day and some system information (the process ID and the parent process ID).

Abstract. We consider the problem of proving that a user has selected and correctly employed a truly random seed in the generation of her RSA key pair. This task is related to the problem of key validation, the process whereby a user proves to another party that her key pair has been generated securely. The aim of key validation is to pursuade the verifying party that the user has not intentionally weakened or reused her key or unintentionally made use of bad software. Previous approaches to this problem have been ad hoc, aiming to prove that a private key is secure against specific types of attacks, e.g., that an RSA modulus is resistant to elliptic-curve-based factoring attacks. This approach results in a rather unsatisfying laundry list of security tests for keys. We propose a new approach that we refer to as key generation with verifiable randomness (KEGVER). Our aim is to show in zero knowledge that a private key has been generated at random according to a prescribed process, and is therefore likely to benefit from the full strength of the underlying cryptosystem. Our proposal may be viewed as a kind of distributed key generation protocol involving the user and verifying party. Because the resulting private key is held solely by the user, however, we are able to propose a protocol much more practical than conventional distributed key generation. We focus here on a KEGVER protocol for RSA key generation. Key words: certificate authority, key generation, non-repudiation, public-key infrastructure, verifiable randomness, zero knowledge 1
