Quantum Secure Proxy-Multi Signature Scheme

Authentication of the information is an important objective in distributed environments. In these environments when the multi-device authentication is required, a significant role is played by proxy-multi signature in diminishing the communication and computation overload. In this paper, we propose the first quantum-resistant proxy-multi signature scheme based on multivariate public key cryptography (MPKC). The security of this scheme depends on the hardness of multivariate quadratic problem. The proposed scheme enjoys the fulfilment of all the required security properties.
