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