Abstract
A method, computing system, and computer-readable medium comprising instructions to establish a chain of trust for components of a computing environment. A respective public/private key pair is generated using a multivariate quadratic function F for each component of the computing environment. In response to a challenge from a verifier, a current prover component sends a response that the verifier uses to determine whether to trust the current prover component. The response may include a first commitment value and a second commitment value, which are determined for the current prover component using a public key of a previous prover component. At least one of the first and second commitment values can be determined using a polar function G, which is a polar form of the multivariate quadratic function F.
