A Survey on Homomorphic Encryption Schemes: Theory and Implementation
, 2017 Legacy encryption systems depend on sharing a key (public or private) among the peers involved in exchanging an encrypted message. However, this approach poses privacy concerns.

Hagedorn divergences and tachyon potential [PDF]
, 2007 We consider the critical behavior for a string theory near the Hagedorn temperature. We use the factorization of the worldsheet to isolate the Hagedorn divergences at all genera. We show that the Hagedorn divergences can be resummed by introducing double

Security considerations for Galois non-dual RLWE families [PDF]
, 2017 We explore further the hardness of the non-dual discrete variant of the Ring-LWE problem for various number rings, give improved attacks for certain rings satisfying some additional assumptions, construct a new family of vulnerable Galois number fields ...

Security Vulnerabilities of Four Signature Schemes From NTRU Lattices and Pairings
IEEE Access, 2020 Certificateless cryptography solves the certificate management problem in public-key cryptography and the key-escrow problem in identity-based cryptography. Xie et al. proposed a certificateless signature scheme using NTRU lattices.

A Non-commutative Cryptosystem Based on Quaternion Algebras
, 2017 We propose BQTRU, a non-commutative NTRU-like cryptosystem over quaternion algebras. This cryptosystem uses bivariate polynomials as the underling ring.

An NTRU-like Message Recoverable Signature Algorithm
MathematicsAn important feature of Nyberg-Rueppel type digital signature algorithms is message recovery, this signature algorithm can recover the original information from the signature directly by the verifier in the verification phase after signing the message ...
