Proxy blind signcryption allow the original user/sender to give there signcryption ability to another entity called proxy. Thus the proxy signcrypter is blindly signcrypt the message on behalf of sender. We investigate that all the existing proxy blind signature and signcryption schemes was suffered from high computational cost and communication overhead. In this paper we designed and analyzed a proxy blind signcryption scheme based on hyper elliptic curve discrete logarithm problem. Also the designed scheme is compared with existing scheme in terms of computational cost and communication overhead. Therefore the proposed scheme has low computational cost and overhead from previous schemes. The scheme is efficient and secure because of hyper elliptic curve cryptosystem.
