Signcryption schemes with threshold unsigncryption, and applications [PDF]
, 2014 The final publication is available at link.springer.comThe goal of a signcryption scheme is to achieve the same functionalities as encryption and signature together, but in a more efficient way than encrypting and signing separately. To increase security

Provably Unforgeable Signatures [PDF]
, 2007 Very strong definitions of security for signature schemes have been proposed in the literature. Constructions for such schemes have been proposed, but so far they have only been of theoretical interest and have been considered far too inefficient for practical use.Here we present a new scheme that satisfies these strongest definitions and uses ...

Incremental Unforgeable Encryption [PDF]
, 2002 The recent selection of the AES block cipher to replace DES has generated interest in developing new modes of operation to supplement the modes defined as part of the DES standard [1,16,23]. We initiate the study of modes of encryption which are both incremental and unforgeable, and point out a number of applications for modes meeting these ...

Two-Round Multi-Signatures from Okamoto Signatures
Mathematics, 2023 Multi-signatures (MS) are a special type of public-key signature (PKS) in which multiple signers participate cooperatively to generate a signature for a single message. Recently, applications that use an MS scheme to strengthen the security of blockchain
