The Quadratic Residue Cipher and some Notes on Implementation
Shepherd SJ, Sanders P, Stockel CT
Cryptologia, June, 1993

Although of similar age, the Quadratic Residue Cipher (QRC) has been neglected compared with the publicity received by other public key cryptosystems, notably the RSA cipher. This paper attempts to redress the balance somewhat, explaining in expository form the principle of the QRC, the advantages it offers over RSA and some experiences gained as a result of using the cipher.
