Cryptanalysis of RSA with private key d less than N/sup 0.292/

WebAbstract: We show that if the private exponent d used in the RSA (Rivest-Shamir-Adleman (1978)) public-key cryptosystem is less than N/sup 0.292/ then the system is insecure. This is the first improvement over an old result of Wiener (1990) showing that when d is less than N/sup 0.25/ the RSA system is insecure. WebApr 7, 2024 · CryptoHack is a fun platform for learning cryptography. The emphasis is on breaking bad implementations of “modern” crypto, such as AES, RSA, and Elliptic-curve.
