Split Knowledge Generation of RSA Parameters
نویسنده
چکیده
We show how it is possible for two parties to cooperate in generating the parameters for an RSA encryption system in such a w a y that neither individually has the ability to decrypt enciphered data. In order to decrypt data the two parties instead follow the cooperative procedure described.

Cheating in split-knowledge RSA parameter generation
Cocks [4] has recently described a protocol for two parties to generate an RSA modulus N = PQ where neither party has knowledge of the factorisation, but which enables the parties to collaborate to decipher a encrypted message. We describe a number of ways in which it is possible for one of the parties to the protocol to cheat and obtain knowledge of the factorisation, and suggest modifications...

متن کاملComparison of two Public Key Cryptosystems
Since the time public-key cryptography was introduced by Diffie andHellman in 1976, numerous public-key algorithms have been proposed. Some of thesealgorithms are insecure and the others that seem secure, many are impractical, eitherthey have too large keys or the cipher text they produce is much longer than theplaintext. This paper focuses on efficient implementation and analysis of two mostpo...
متن کاملOff-line/On-line Generation of RSA Keys with Smart Cards
Standard bodies and organizations are pushing for increasingly larger RSA keys. Today, RSA keys range from 512 bits to 2048 bits and some bodies envision 4096-bit RSA keys in the near future. This paper devises a new methodology for generating RSA keys. Contrary to what is usually done, the key generation is divided into two phases. The first phase is performed off-line, before the input parame...
متن کاملP-74: Cytochemical Evaluation of Sperm Chromatin and DNA Integrity in Couples with 3 Unexplained Recurrent Spontaneous Abortion
Background: The aim of this study was to examine the possible relationship between sperm DNA integrity and chromatin packaging evaluated by cytochemical assays, traditional sperm parameters and recurrent spontaneous abortion (RSA) of unknown origin. Materials and Methods: In this cohort study, 40 couples with a history of RSA and 40 couples with proven fertility were considered as case and cont...
