A software distribution method (300) with security add-on is proposed. Particularly, any software package to be deployed to selected target endpoints is encrypted (312-315) with a symmetric key (generated dynamically). The symmetric key is in turn encrypted (318-321) with a public key of each target endpoint. A multi-segment software package (embedding the encrypted software package and the encrypted symmetric keys) is then deployed (324-336, 360) to all the target endpoints. In this way, each target endpoint can decrypt (343-348) the encrypted symmetric key with a corresponding private key; it is then possible to decrypt (363-366) the encrypted software package with the symmetric key so obtained. As a result, the endpoint is able to apply (369) the decrypted software package. Therefore, the application of the software package can be restricted to the desired target endpoints only.

An owner controlled file protection and control system that uses a protected file that is encrypted and has embedded with access and use control features. The file is selected and encrypted and combined with a set of encrypted policy rules by an encryption software program. The policy rules are one or more ‘access rules’ and ‘use rules’ that determine who, what, when, and where the protected file may be accessed and how the protected file will be used. They may be selectively changed at any time and may be location, time and date sensitive. The protected file may be sent to the recipient or stored in a file that the recipient may accessed. During use, each recipient must register with the system and is assigned a registered ID. Using the ‘access rule’, the owner may assign a particular recipient ID to the protected file. A recipient then uses a reader program to generate a request to access and use the protected file to a management server. Management server then reviews the policy rules associated with the protected file to determine if they are satisfied. If the rules are satisfied, then time sensitive digital certificate is sent to the recipient that allows the protected file to be accessed and used according to the policy rules.
