The presentation of the primitives provides also the formal security notions that are needed later in our study. The following two sections consider a

Since establishing a formal security model for a cryptographic system is a real challenge and divergence between cryptographers, we subject the model we adhere to to an in-depth comparison with the already established ones; our

An Efficient Variant of StEondition on the base encryption excludes a class of encryption schemes that allows for a great efficiency of the confirmation/denial protocols. In this chapter, we propose an effective variation of StE; we demonstrate its efficiency by explicitly describing the confirmation/denial protocols when the

CtEtS: An Efficient Variant of CtEaS. This makes the paradigm rest on strong encryption (. secure), and rules out consequently homomorphic encryption which is known for propping up verification. In this chapter, we annihilate this weakness and demonstrate the efficiency of the resulting construction by describing many concrete instant

EtStE: A New Paradigm for Verifiable Signcryptionncryption, these paradigms fail to give similar results. The reason lies in the fact that encryptions are produced on the message, to be signcrypted, in addition to other strings (signatures or decommitments), which renders verification ineffective. The subject of this chapter is a new paradigm for

Multi-User Securityse. This setting is too simplistic to represent reality, where it is customary to have a network of many users that want to exchange signcrypted messages. Also, it is not uncommon in case of confirmer signatures, to have many signers that share the same confirmer, or conversely a signer who has many
