Abstract: A system, method, and computer program product are provided for implementing hardware backed symmetric operations for password based authentication. In operation, a system receives a request to access software utilizing password-based authentication. Further, the system receives a password for the password-based authentication. The system computes a hash utilizing the password and a hardware-based authenticator associated with hardware of the system utilizing hardware backed symmetric encryption. Moreover, the system verifies that the hash computed utilizing the password and the hardware-based authenticator is correct for accessing the software.

Abstract: A system, method, and computer program product are provided for end-to-end security of centrally accessible group membership information. In use, membership information defining a user group in a messaging system is accessed from a central server, where the membership information includes (1) at least one change to members of the user group, and (2) for each change of the at least one change, a digital signature of a user that made the change. Additionally, a verification process on the membership information is performed, including: for each change of the at least one change, verifying the digital signature of the user that made the change. Further, members of the user group are determined, as a result of the verification process, and at least one action is performed in association with the members of the user group.

Abstract: An apparatus, computer program, and method are afforded for providing a peer-to-peer security protocol. In operation, a message is identified that is directed from a first peer device to a second peer device. Further, the message is copied, so that a copy of the message is caused to be sent to an auditing server.
