A modification of the RSA public-key encryption procedure (Corresp.)
H. Williams · IEEE Transactions on Information Theory · 1980
The Rivest, Shamir, and Adleman (RSA) public-key encryption algorithm can be broken if the integerRused as the modulus can be factored. It my however be possible to break this system without factoringR. A modification of the RSA scheme is described. For this modified version it is shown that, if the encryption procedure can be broken in a certain number of operations, thenRcan be factored in only a few more operations. Furthermore, this technique can also be used to produce digital signatures, in much the same manner as the RSA scheme.
