A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs
IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

Some lattice attacks on DSA and ECDSA [PDF]
Applicable Algebra in Engineering, Communication and Computing, 2011 This paper develops attacks on DSA and ECDSA using the algorithm for LLL reduction and two algorithms for the computation of the integral points of two classes of conics, provided that the secret and the ephemeral key of a signed message or their modular inverses are sufficiently small and in case the ephemeral keys or their modular inverses of two ...
