Selective encryption in mobile devices

摘要

A method, product and system for selective encryption in a mobile device. The method comprising: selectively encrypting requests issued by the mobile device, wherein said selectively encrypting comprises: obtaining a request issued by an application executed by the mobile device, the request having one or more characteristics, the request has a destination; determining, based on the one or more characteristics, whether to encrypt the request; and in response to a determination to encrypt the request, re-routing the request to be transmitted to the destination through a secure channel; whereby the request is encrypted regardless of the destination being a priori associated with the secure channel.

1. A computer-implemented method performed by a mobile device having a processor and memory, the method comprising:
receiving a dynamically generated Proxy Auto Config (PAC) file, the PAC file is generated automatically by a rules provider, wherein the rules provider selects one or more rules from a rules database to be applied by the PAC file, wherein the one or more rules are rules useful for determining whether or not to encrypt a request issued by the mobile device; selectively encrypting requests issued by the mobile device, wherein said selectively encrypting comprises:
obtaining a request issued by an application executed by the mobile device, the request having one or more characteristics, the request has a destination;determining, based on the one or more characteristics, whether to encrypt the request, wherein said determining is performed by applying the rules in the PAC file; andin response to a determination to encrypt the request, re-routing the request to be transmitted to the destination through a secure channel, wherein said re-routing the request is performed by sending the request to a proxy defined by the PAC file, wherein traffic to the proxy is tunneled through the secure channel;whereby the request is encrypted regardless of the destination being a priori associated with the secure channel.
