In November 2016 Gus Gutoski and Christopher Peikert independently informed us about a flaw in the security reductions presented in the papers corresponding to the schemes TESLA and ring-TESLA.We published a new (tight) security reduction for TESLA on PQCrypto 2017. We also updated the parameter an the implementation. However, ring-TESLA and its proposed parameters are still not supported by any formal security argument.
