Hi Aryan, These are some known records for calculating the discerete log problem. For GF(p) ... April 17 2001,discrete logarithms modulo a 120 digits prime was...

Is there any (asymmetric) deterministic encryption scheme that is CCA2 secure. For instance RSA is not. -- Computer Science & Computer Engineering La Trobe...
sorry there was a mistake in my earlier email A deterministic scheme cannot be CCA secure. What I need is a determinisitic scheme that resists this attack ...
... No The attacker sends E(M1), E(M2) separately (and an operation of what he wants) ... However RSA breaks down when we also give the attacker the sum of ...
Hi, ... Yes,that is true. The point was that the attacker can compute E(M1)*E(M2), since he knows C1=E(M1), C2=E(M2) and that the homomorphism follows. ... ...

Hello, ... Thank you! ... That is true, the homomorphsim only holds when m1*m2<p. If, m1*m2>p , then there is clearly a modular reduction, when you compute...
No we cannot afford to lose any bits of the result mod p, since we want to preserve the ring structure of Z_p in the ciphertexts. This the message space must...
Hi, ... If we are looking at homomorphic encryption schemes, it seems to be an open problem (preserving the ring structure of the message), from the abstract...

Hello What do you exactly mean by "..working on elliptic curve based stream ciphers"? Am I right if I say you are trying to construct a pseudorandom bit stream...
