Doubly Spatial Encryption from DBDH, by Jie Chen and Hoeteck Wee
Functional encryption is an emerging paradigm for public-key encryption which enables fine-grained control of access to encrypted data. Doubly-spatial encryption (DSE) captures all functionalities that...

Reputation systems are used to compute and publish reputation scores for services or products. We consider reputation systems where users are allowed to rate products that they purchased previously. To...
View ArticleAuthentication Schemes Based on Resilient Maps, by Juan Carlos Ku-Cauich and...
We introduce four constructions of systematic authentication codes. The first two are built over finite fields using resilient functions and they provide optimal impersonation and substitution...
View ArticleImplicit factorization of unbalanced RSA moduli, by Abderrahmane Nitaj and...
Let N1 = p1q1 and N2 = p2q2 be two RSA moduli, not necessarily of the same bit-size. In 2009, May and Ritzenhofen proposed a method to factor N1 and N2 given the implicit information that p1 and p2...
View ArticleNew Attacks on the RSA Cryptosystem, by Abderrahmane Nitaj, Muhammad Rezal...
This paper presents three new attacks on the RSA cryptosystem. The rst two attacks work when k RSA public keys (Ni, ei) are such that there exist k relations of the shape eix-yi\phi(Ni)=zi or of the...
