“…In 2002, Malone-Lee [4] merged identity-based cryptography with signcryption and designed a new ID based signcryption (IBSC) scheme. This IBSC scheme [4] provides foundation for some other identity based signcryption and its variant [5][6][7][8][9][10][11][12][13][14].…”

Secure data transmission is a challenging issue in modern data communication. ID based generalized signcryption is a cost effective security primitive which provides authentication or confidentiality, or jointly confidentiality and authentication. Wei's proposed an ID based generalized signcryption scheme for authentication and confidentiality of big data in a standard model, claiming that their scheme holds the security of indistinguishability against adaptive chosen-ciphertext attacks and existential unforgeability against adaptive chosen message attacks. In this paper, we analyzed Wei's scheme by launching security attacks on the scheme to check its validity. As a result, it became clear and proved that the master secret key generated in the scheme is compromisable. Similarly, the mentioned scheme does not hold the security of indistinguishability against adaptive chosen-ciphertext attacks and existential unforgeability against adaptive chosen message attacks. Consequently, Wei's schemes is prone to attacks and is insecure.

“…The first identity based signcryption scheme was proposed by Malone Lee [8] in 2002, and they also gave the security model for signcryption in identity based settings. Since then, many identity based signcryption schemes have been proposed [9][10][11][12][13][14][15][16][17].…”

Generalized signcryption (GSC) can adaptively work as an encryption scheme, a signature scheme or a signcryption scheme with only one algorithm. It is more suitable for the storage constrained setting. In this paper, motivated by Paterson-Schuldt's scheme, based on bilinear pairing, we first proposed an identity based generalized signcryption (IDGSC) scheme in the standard model. To the best of our knowledge, it is the first scheme that is proven secure in the standard model.

“…This property is also needed in filtering out spams in a secure email system. Although a number of constructions [3,46,17,38,45] have tackled the notion of verifiability (this notion is often referred to in the literature as public verifiability, and it denotes the possibility to release (by the receiver) some information which allows to publicly verify a signcryption with/out revealing the message in question), most of these schemes do not allow the sender to prove the validity of the created signcryption, nor allow the receiver to prove without revealing any information, ensuring consequently non-transferability, to a third party, the validity of a signcryption w.r.t. a given message.…”

Abstract. Signcryption is a primitive which simultaneously performs the functions of both signature and encryption in a way that is more efficient than signing and encrypting separately. We study in this paper constructions of signcryption schemes from basic cryptographic mechanisms; our study concludes that the known constructions require expensive encryption in order to attain confidentiality, however some adjustments make them rest on cheap encryption without compromising their security. Our constructions further enjoy verifiability which entitles the sender or the receiver to prove the validity of a signcryption with/out revealing the signcrypted message. They also allow the receiver to release some information which allows anyone to publicly verify a signcryption on a given message. Finally, our constructions accept efficient instantiations if the building blocks belong to a wide class of signature/encryption schemes.
