Every d(d + 1)-connected graph is globally rigid in Rd

Using a probabilistic method, we prove that $d(d+1)$-connected graphs are rigid in $R^d$, a conjecture of Lovász and Yemini. Then, using recent results on weakly globally linked pairs, we modify our argument to prove that $d(d+1)$-connected graphs are globally rigid, too, a conjecture of Connelly, Jordán and Whiteley. The constant $d(d+1)$ is best possible.
