The mechanism of public key infrastructure(PKI) and identity-based encryption(IBE) is analyzed to solve the safety problems of E-government system,and a safety solution based on hierarchical IBE(HIBE) is proposed for E-government system.With HIBE as its core,this solution utilizes such methods as: any string of the user identity as public key;strict verification of user identity;elliptic curve encryption;and setting up hierarchical key server,etc.to ensure the confidentiality,integrity,serviceability,and non-repudiation during data transmission and storage.This effectively deals with such problems as high deployment cost,complicated identity verification,key escrow and low efficiency of PKI and IBE mechanism.The theoretical and experimental analyses indicate that the safety problems of E-government system is better solved and this mothod has promising application prospect.
