Performance and analysis of NTRU and Advanced NTRU cryptosystems

Authentication and Confidentiality is the main goal of the public key cryptosystems deal when communication takes place between both the parties. The mostly used cryptographic methods are broadly classified as symmetric and asymmetric. The DES comes under the category of symmetric key cryptosystem whereas RSA, NTRU[1] belongs to the category of asymmetric key cryptosystem. NTRU (Nth degree trun...

NTRU Prime

Several ideal-lattice-based cryptosystems have been broken by recent attacks that exploit special structures of the rings used in those cryptosystems. The same structures are also used in the leading proposals for post-quantum lattice-based cryptography, including the classic NTRU cryptosystem and typical Ring-LWE-based cryptosystems. This paper proposes NTRU Prime, which tweaks NTRU to use rin...

NTRU in Constrained Devices

The increasing connectivity o ered by constrained computing devices signals a vital need for public-key cryptography in such environments. By their nature, however, public-key systems have been diÆcult to implement in systems with limited computational power. The NTRU public-key cryptosystem addresses this problem by o ering tremendous performance enhancements over previous practical systems. T...

Quantum Cryptanalysis of NTRU

This paper explores some attacks that someone with a Quantum Computer may be able to perform against NTRUEncrypt, and in particular NTRUEncrypt as implemented by the publicly available library from Security Innovation. We show four attacks that an attacker with a Quantum Computer might be able to perform against encryption performed by this library. Two of these attacks recover the private key ...

Current Attacks on NTRU

Acknowledgements I should thank many people who have helped me on the way of writing and then righting what you read now. I start with my family, whose love and support have been the very foundation of all my studies. I thank Professor Buchmann, who interested me in the field of lattice cryptography and arranged this thesis. I thank my first supervisor Christoph Ludwig, for many talks about lat...
