| Abstract: | This paper analyzes the main threats that instant messaging(IM) confronted,its characteristics,and solutions in existing applications,proposes a suit of strategies to secure IM.This paper introduces the public key infrastructure(PKI) mechanism into IM,adopting techniques such as security socket layer(SSL) and CAPTCHA,and methods such as encryption,signature,signature verification,decryption,CAPTCHA validation and IM message flux monitoring,so as to ensure the security of IM connections and data communications,protect the configurations and notes of IM system,and lighten viruses and worms threats. |
