Comparative Analysis of Key Encapsulation Mechanisms
2019 10th IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications (IDAACS), 2019The paper deals with the possible comparative analysis methods of the cryptographic primitives' properties. Methods of comparative analysis – analytic hierarchy process and variations of weight indices methods are investigated and analyzed. Conclusions are made and recommendations on the use of the cryptographic primitives' estimation methods are ...

Generic Certificateless Key Encapsulation Mechanism
2007We propose the first generic construction of certificateless key encapsulation mechanism (CL-KEM) in the standard model, which is also secure against malicious-but-passive KGC attacks. It is based on an ID-based KEM, a public key encryption and a message authentication code.

Efficient constructions of certificate-based key encapsulation mechanism
International Journal of Internet Protocol Technology, 2014Certificate-based encryption is a useful primitive that combines identity-based encryption and traditional public key encryption while preserving some of their most attractive features. It not only simplifies the cumbersome certificate management in traditional public key encryption, but also overcomes the key escrow and distribution problems inherent ...

Public Verifiable Key Encapsulation Mechanism under Factoring
2013 5th International Conference on Intelligent Networking and Collaborative Systems, 2013The cipher text consistency check that can be implemented publicly has practical significance, and it is always an interested studying aspect to construct cryptographic algorithm without pairings in the field of cryptographic. On the other hand, it is one of the most important research topics to design CCA-secure PKE schemes with weaker assumptions ...

Compact and Simple RLWE Based Key Encapsulation Mechanism
2019In this paper, we propose a key encapsulation scheme based on NewHope and Kyber, two NIST post-quantum standardization project candidates. Our scheme is based on NewHope, thus it is simple and has fast implementation while it is making use of smaller key sizes and easily changeable security level advantages of Kyber .

Recommendations for key-encapsulation mechanisms
A key-encapsulation mechanism (KEM) is a set of algorithms that can be used by two par-ties under certain conditions to securely establish a shared secret key over a public channel. A shared secret key that is established using a KEM can then be used with symmetric-key cryptographic algorithms to performGorjan Alagic +6 more
