    Code signing technology marks the application with a digital signature in a coding type that verifies the software author and offer guarantee that the code is unique and not tainted. Unsigned software faces many obstacles like unauthorized identity, spyware, malware, harmful code. Once a code signing process done the customer gain trust in author and download the software easily. Code signing feature warn the installer if the publisher could not be found trustworthy. Code signing feature add an extra level faith to the application installation process.

    Code signing operation can flawlessly incorporated with application and abolish the physical signing saddle for developers. There exists many code signing authorities but Symantec and Thawte are the most trusted certificate authorities. Such security removes the Unknown Publisher pop-up in internet explorer and window OS. Developers should have ability to catch defective or compromised code without disturbing legitimate applications of other developers.

    Due to spread of Wi-Fi technology It is arduous to decide an identity of publishers not affect a single user’s Smartphone but can hazardous to entire network and welcome malicious subscribers to harass by interrupting service and can harm the network provider’s reputation. New mobile software platform such as window Mobile 7 has applied code signing technology to control the software permission on network.

    For a digital signature, one should deliver a public and private key. Private Key practiced to sign up the data and the Public key enforced to affirm the signature of the data. Here two identities should clear as publishers who create and signs software with code signing certificate and Distributor who publish software to users.

    How Code Signing works:

    • Certificate Authority (CA) authenticates a developer’s identity.
    • CA issue the developer a development ID utilize for sign code.
    • Developer utilizes ID to sign the data file of an application and send to CA.
    • Finally, authenticated content is ready to deal out.

    Benefits of Code Signing Security:

    • Customer affirms confidence that code is downloaded is authenticated and not corrupted.
    • Code signing security enhances reputation of business as applications are in well form of validation.
    • It smoothly integrated with browsers as per industry standard technology.
    • It is comfy to employ with software tools created by developers.
    • It is easy available from various online certificate providers.
    • User can well detect by pop up whether software is from valid publisher or not.
    • It is functional in major languages with less cost and high scalability.

    Many CA now frees developer to recall a key by developing a cloud protection where developer upload an application and the system will uphold the key for a lifetime hence future time developer has to submit only the newest edition of application and the key will identify the developer.
