Abstract: A method is performed by a computer in communication with a hardware security module (HSM). The method includes (a) running a process virtual machine (PVM) on the computer, the PVM being configured to execute portable bytecode instructions within a PVM environment and (b) executing, within the PVM environment, instructions for (1) reading encrypted instruction code from data storage of the computer, (2) sending the encrypted instruction code to the HSM, (3) in response, receiving decrypted instruction code from the HSM, and (4) injecting the decrypted instruction code within an application running in the PVM environment for execution by the PVM. Embodiments are also directed to analogous computer program products and apparatuses.

Abstract: A method is used in validating association of client devices with sessions. Information of a client device executing a user agent is gathered by a server for creating a device identifier for the client device upon receiving a request from the user agent for establishing a session between the user agent and the server. The device identifier includes information identifying the client device. The device identifier is associated with the session. The client device is validated by the server upon receiving subsequent requests from the client device during the session. Validating the client device includes gathering information of the client device sending each subsequent request for creating a device identifier for the client device and comparing the device identifier created from the information gathered during each subsequent request with the device identifier associated with the session.

Abstract: A method is used in validating association of client devices with authenticated clients. An authentication request for authenticating a client is received from a client device used by a client for establishing a session with a server. The client is authenticated by an authentication device. A token is created and provided to the client device. Identification information of the client device is gathered. The identification information identifies the client device. The identification information gathered from the client device is evaluated. Based on the evaluation, it is validated that the identification information corresponds to a client device associated with the authenticated client.
