In recent years it has been trying that with regard to the question of computational complexity of discrete logarithm more strength and less in the elliptic curve than other hard issues, applications such as elliptic curve cryptography, a blind  digital signature method, other methods such as encryption replacement DLP. In this paper, a new blind digital signature scheme based on elliptic curve...

We initiate a study of the security of cryptographic primitives in the presence of efficient tampering attacks to the randomness of honest parties. More precisely, we consider p-tampering attackers that may tamper with each bit of the honest parties’ random tape with probability p, but have to do so in an “online” fashion. We present both positive and negative results: • Negative Results: Any s...

We extend the notions of correlation-immune functions and resilient functions to functions over any finite alphabet. A previous result due to Gopalakrishnan and Stinson is generalized as we give an orthogonal array characterization, a Fourier transform and a matrix characterization for correlation-immune and resilient functions over any finite alphabet endowed with the structure of an Abelian g...

Synthesizing the emerging directions of research at intersection differential privacy and cryptography.

Abstract In our modern digital society, cryptography is vital to protect the secrecy and integrity of transmitted stored information. Settings like commerce, electronic banking, or simply private email communication already rely on encryption signature schemes. However, today’s cryptographic schemes do not scale well, thus are suited for increasingly large sets data they used on. For instance, ...

a resilient soft liner (rsl) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture's intaglio surface. use of a thermoplastic vacuum-formed template and an endodontic k-file, as guides, for the reduction of a processed mandibular complete denture to receive rsl is described in the present report. a proce...
