碩士 === 國立交通大學 === 資訊科學學系 === 86 === The thesis proposed a system for signing Java applets.The overall system consists of two parts.The first part is called Key Manager,while the second partis called Simple Browser.The function of the first part is to manage public/private keys and sign applets.The second part is a testing platform for executingthe signed applets based on our approach.The RSA public-key algorithm is used as the signingfunction.The first 128 bytes of applets are encryptedand are treated as the signature of applets.The author of an applet uses his own private key to encrypt the applet while the others use the corresponding public key to decrypt the applet before executing the signed applet.The incorrect signature will result in the incorrect format of the appletand cause the applet not executable.The system can then certificate whether the applet comes from the trusted source or not.
