In this paper we examine the techniques of adjusting the
RSA algorithm to allow multisignatures being simply
applied by many users. The proposed algorithms will be
suitable for employ in organizations. However, general
uses might be the signing of cheques for electronic funds
transfer where two or more organization representatives
are needed to sign the cheque.
The algorithms suggested in this paper are not restricted
to RSA scheme. It means that every encryption algorithm
e with the multiplicative ability e(k1) * e(k2) = e(k1 * k2)
will work. For concreteness, however, we will employ
RSA widely in this paper.
