On the Security of Joint Signature and Encryption
TL;DR: It is shown that gCCA2-security suffices for all known uses of CCA2-secure encryption, while no longer suffering from the definitional shortcomings of the latter.
Concealment and its applications to authenticated encryption
Yevgeniy Dodis,Jee Hea An +1 more
TL;DR: In this article, the authors introduce the notion of concealment, which is related to commitment but quite different from commitment, and show that concealments are exactly the right abstraction allowing one to use authenticated encryption for encrypting long messages.

On the Security of Joint Signature and Encryption.
TL;DR: In this article, the notion of joint signature and encryption in the public-key setting has been formally studied and two definitions for the security of signcryption depending on whether the adversary is an outsider or a legal user of the system were presented.

Security for Signcryption: The Two-User Model
Jee Hea An,Tal Rabin +1 more
TL;DR: It is shown that signcryption can be viewed as the public-key version of the symmetric-key primitive known as authenticated encryption ; indeed, the two primitives share many similarities at a high level.
