On the Security of Tag-KEM for Signcryption
Electronic Notes in Theoretical Computer Science, 2007 AbstractSigncryption tag-KEM (Key Encapsulation Mechanism with a tag) is an authenticated tag-KEM for generic construction of hybrid signcryption. Signcryption tag-KEM allows the sender to encapsulate a symmetric key along with a tag so that the receiver can authenticate the sender, the key, and the tag.

Key Encapsulation Mechanisms (KEMs) are a critical building block for hybrid encryption and modern security protocols, notably in the post-quantum setting. Given the asymmetric public key of a recipient, the primitive establishes a shared secret key between sender and recipient.

A Prolog Implementation of Kem. [PDF]
, 1995 In this paper, we describe a Prolog implementation of a new theorem prover for (normal propositional) modal and multi--modal logics. The theorem prover, which is called $KEM$, arises from the combination of a classical refutation system which incorporates a restricted ("analytica") version of the cut rule with a label formalism which allows for a ...

A generic or KEM-DEM hybrid construction is a formal method for combining asymmetric and symmetric encryption techniques to give an efficient, provably secure public-key encryption scheme. This method combines an asymmetric key encapsulation mechanism (KEM) with a symmetric data encapsulation mechanism (DEM).

Insider-Secure Signcryption KEM/Tag-KEM Schemes Without Random Oracles
2008 Third International Conference on Availability, Reliability and Security, 2008In this paper, we propose a signcryption key encapsulation (KEM) scheme and show that the proposed scheme is insider-secure against adaptive chosen ciphertext attack without random oracles and against strongly existential forgery without random oracles.

Efficient KEMs with Partial Message Recovery
2007Constructing efficient and secure encryption schemes is an important motivation for modern cryptographic research. We propose simple and secure constructions of hybrid encryption schemes that aim to keep message expansion to a minimum, in particular for RSA-based protocols.
