To　strengthen　proxy　signature　security,　and　based　on　the　analysis　of　blind　signature　scheme　in　being,　this　paper　proposed　a　proxy　signature　scheme　based　on　the　hyperelliptic　curve　cryptography.　Furthermore,　it　analyzed　the　security　problem.　Through　transplanting　a　proxy　signature　arithmetic　into　hyperelliptic　curve　cryptography,　it　proposed　a　proxy　signature　arithmetic　which　was　based　on　the　hyperelliptic　curve　cryptography.　Proxy　signature　scheme　based　on　the　hyperelliptic　curve　cryptography　is　better　than　that　of　elliptic　curve　cryptography　on　performance　of　security.　It　plays　a　better　role　in　electronic　commerce　and　network　security.
