Abstract: Based on the Public-Key Infrastructure (PKI) system and asymmetric encryption algorithm, the traditional XML signature has many drawbacks such as complex management process and high computational cost. By the research of XML signature syntax and Identity Based Signature (IBS) scheme without a trusted third-party, the author realized a new XML signature based on the above IBS system and Weil pairing correspondingly，and designed the corresponding XML signature process and structure of XML signature according to the XML signature syntax. The new XML signature overcomes the drawbacks of traditional signature based on the PKI with good security and high efficiency.

Key words: XML digital signature
