Digital Signature and Multiple Signature: Different Cases for Different PurposesAdded by Papergrl
Description:
Like paper-based signatures, digital signatures intend to respect a number of security assumptions. Methods of digital signature apposed by a single user have been defined and are widely used. But is it sufficient? What if a legal document requires witnesses and notarization, or a contract needs the signatures of several officers? This paper will first show the basics to understand digital signatures and how the security properties of integrity, authentication, and non-repudiation are respected. We will then present the purposes of multiple signature schemes and introduce a possible classification of cases that need multiple signatures. This paper is not intended as a presentation of a particular multiple signature scheme, but the classification presented should help researchers identify more appropriate new multiple signature schemes.
