System and method for secure inter-process data communication

A system and method for secure inter-process data communication is provided. Identification data corresponding to a user is received and used to generate a symmetric encryption key. The symmetric encryption key is then used to encrypt job data. A token associated with the encrypted job data is then generated. Expiration data corresponding to the validity period of the token is then associated with the token, whereupon the token is stored. The generated symmetric key is then encrypted using a static symmetric encryption key, whereupon the encrypted symmetric key is also stored in association with the token. When a process receives the encrypted job data, the process retrieves the token and determines, based on the expiration data whether the token is still valid. When the token is valid, the static key is retrieved and used to decrypt the encrypted encryption key. The decrypted encryption key is then used to decrypt the job data, whereupon the process performs the function associated therewith upon the decrypted job data.
