Information technology. Security techniques. Digital signature schemes giving message recovery - Integer factorization based mechanismsDigital signature mechanisms can be used to provide services such as entity authentication, data origin authentication, non repudiation, and integrity of data. A digital signature mechanism satisfies the following requirements: Given the verification key but not the signature key it shall be computationally infeasible to produce a valid signature for any message Given the signatures produced by a signer, it shall be computationally infeasible to
