Systems, methods, and other embodiments associated with aggregation of cryptography engines are described. One example method includes receiving an outbound data packet on an outbound side of a data connection. The example method may also include analyzing the outbound data packet to determine a distribution value. The example method may also include selectively distributing the outbound data packet to one of a plurality of outbound processors based, at least in part, on the distribution value. The example method may also include receiving an inbound data packet on an inbound side of the data connection. The example method may also include examining the inbound data packet for an identifier. The example method may also include selectively distributing the inbound data packet to one of a plurality of inbound processors based, at least in part, on the identifier.

Aggregation of cryptography engines

A method and apparatus for protecting secured files stored on a file system employs a file security status associated with each file to signal whether or not access to the file is allowed. The file security status is stored in a fixed location in memory. Upon opening the associated file, the file security status is copied to a second location in memory. Depending upon the file security status stored in the second location, operations on the file by a client are either allowed or denied. Operations on non-secure files are always allowed. Operations on secured files are allowed only after verification of the client's authorization to access the file and the subsequent modification of the file security status stored in the second memory location. The method protects secured files from deletion by unauthorized clients. This is accomplished by, upon opening a secure file, initializing a third memory location to a value indicating that the file will not be deleted upon closing. This value may be changed by an authorized client only after going through the above-described verification process. Once the value has been changed to reflect that the file should be deleted when closed, the file will be deleted when closed. A method for creating a new secure file is also provided.
