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. WebSoulcrabber II: Rust RNG initialised with current time.

Using BSGS we found e 1 such that c 1 = m 1 e 1 mod n. However when we compute a matching private exponent d 1 [e.g. per d 1 := e 1 − 1 mod ( ( p − 1) ( q − 1)) ] then compute m 2 := c 2 d 1 mod n we get an m 2 that ...
