With the development of the electronic commerce and the deepening of it's application, more importance is attached to the security of the online trading. How to insure the safety > confidentiality > integrity and non-repudiation of the trading information has become urgently to be solved. By using the public key infrastructure certificate authority and it's digital certificate, can solve the above problems, and at the same time can guarantee the reliability of people's identity. Certificate authority( CA ) is the impartial, authoritative third party in the trading of electronic commerce .This thesis mainly discussed CA and something related to it in electronic commerce, including encryption and decryption algorithm( DBS, RSA ), digital signature, digital certificate, the constitution and the function of CA in electronic commerce , the development status and the problems encountered of the CA in our country. After careful comparison and analysis, I propose some ideas and suggestions of myself. At the last chapter, by discussing the securities online trading, I propose three possible means to prove the investor's identity, they are: building CA of the stock company, building RA ( register authority) and building LRA (local RA) .
