Abstract
An approach is provided for building a scalable service platform by initiating transmission of encrypted data from a public network cache. An access control server platform determines a first authorization key for a user and a second authorization key for a resource, and then encrypts the resource with the second authorization key, and encrypts the second authorization key with the first authorization key. The access control server platform initiates distribution of the encrypted second authorization key with the encrypted resource over a network. The access control server platform further initiates caching the encrypted second authorization key with the encrypted resource that meets a predefined threshold value (e.g., a data size, an access frequency, a modification frequency, or an auditing requirement) in a cache in the network, and initiates transmission of the cached and encrypted second authorization key with the cached and encrypted resource from the cache to at least one authorized entity.
