A method and system for providing secure access to a device initiating communications using a peer-to-peer signaling protocol, such as a SIP or H.323. In a device registration phase, the device contacts a secure access server, and authenticates to the secure access server by providing an identification, such as its factory ID. The secure access server then issues a device ID and private key to the authenticated device. A client can then initiate a further communication session and be authenticated by the secure access server. The secure access server returns the device identification and the device's public key to the client. The client and device can then perform a symmetrical key exchange for their current communication session, and can communicate with appropriate encryption. The device's private key can be set to expire after one or more uses.

A multi-user file storage service and system enable each user of a pre-subscribed user group to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Additionally, an encrypted key is transferred from the file server node to a particular client node via a secure channel. The encrypted key uses an encryption function and a decryption function not known locally at the remote file server. Furthermore, both privileged access control rights and file sharing mode access control to a particular file of the group of files are delegated to one or more distributed nodes other than the remote file server node which provides the data.

A multi-user file storage service and system enable each user of a pre-subscribed user group to operate an arbitrary client node at an arbitrary geographic location, to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node in communication with the remote file server node via the wide area network. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Illustratively, the integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Thus, all native operating system application programming interfaces operate as if all multi-user applications accessing the files function as if the remote server and client nodes were on the same local area network. Illustratively, an interface is provided for adapting file access one of the client nodes. The interface designates at the client node each accessible file of the group as stored on a virtual storage device. The interface enables access to the designated files in a fashion which is indistinguishable, by users of, and applications executing at, the client node, with access to one or more files stored on a physical storage device that is locally present at the client node. Illustratively, an encrypted key is transferred from the remote file server node to one of the client nodes via a secure channel. The key is encrypted using an encryption function not known locally at the remote file server node. The transferred key is decrypted at the client node. The key is used at the client node to decrypt information of the files downloaded from the remote file server node or to encrypt information of the files prior to uploading for storage at the remote file server node. Access control to a particular one of the files of the group can be delegated to an access control node.

The present invention provides systems and methods for supporting encrypted communications with a medical device, such as an implantable device, through a relay device to a remote server, and may employ cloud computing technologies. An implantable medical device is generally constrained to employ a low power transceiver, which supports short distance digital communications. A relay device, such as a smartphone or WiFi access point, acts as a conduit for the communications to the internet or other network, which need not be private or secure. The medical device supports encrypted secure communications, such as a virtual private network technology. The medical device negotiates a secure channel through a smartphone or router, for example, which provides application support for the communication, but may be isolated from the content.

Embodiments of the present invention provide a secure remote password reset capability. In some embodiments, an exemplary method provides a remote reset of a password associated with a token in a computer system having a security server. A token-based authentication process is activated by connecting the token to the security server. A server-based authentication process is initiated in the security server by activating a password reset process in a security client. The server-based authentication process communicates with the token-based authentication process over a secure channel. An authentication credential is managed by a third party agent that supplies a query and the authentication credential as a correct response to the query to the security server. A prompt provided by the password reset process collects the authentication credential and a new password. After the authentication credential is validated mutually authentication is performed between the security server and the token. The token is updated with the new password based on a successful result of the mutual authentication.

Problem The combination of a tendency towards permissivity when verifying certificate authenticity and the use of in-band client authentication opens up an opportunity for attackers to mount man-in-the-middle attacks on SSL connections.Solution The invention exposes any discrepancy between the intended recipient of the client credential and the actual recipient of the client credential by cryptographically including parameters that are uniquely linked to the channel (i.e., the communication session, as characterized by the parameters of the protocols that are being used), preferably the channel end points, in the calculation of the client credential. This links the process that provides the secure channel (e.g., the SSL protocol session) to the process that provides the authentication credential (e.g., the OTP token operation), thus exposing any attack that would break up the client-server channel. This is achieved without the requirement for an additional encrypted tunnel and allowing the continued use of existing components such as existing browsers.

A method and system to support secure booting and configuration. The mechanism employs an optical link comprising a quantum channel that is used to send data encoded as quantum bits (qubits) via respective photons. Qubits encoded using a first random basis at the client and are sent to the boot server, which processes the qubits using a second random basis to extract the encoded data. A public channel is used to send data indicative of the second random basis to the client. A symmetric quantum key is then derived a both the client and the boot server using a comparison of the random basis' and the original and extracted data. The scheme enables the presence of an eavesdropper to be detected on the quantum channel. A DHCP message exchange is employed to obtain a network address, and, optionally, be provided with a network address for one or more boot servers. A boot image request is made to the boot server by the client, and a subsequent boot image is downloaded via a secure channel facilitated by the symmetric quantum key.

Apparatus and computer-readable media are disclosed for establishing secure multicast communication among multiple multicast proxy service nodes of domains of a replicated directory service that spans a wide area network. Domains are organized in a logical tree. Each domain has a logical tree that organizes the multicast proxy service nodes, a group manager at the root node, a multicast key distribution center, multicast service agent, directory service agent and key distribution center. Multicast proxy service nodes store a group session key and a private key. Replication of the directory performs key distribution. A multicast group member joins or leaves the group by publishing message. The local key distribution center and multicast service agent obtain the publisher's identity from a local directory service agent. Based on the identity, a secure channel is established with the directory service agent in the group member's domain. Keys of the binary tree branch that contains the joining or leaving node are updated, and an updated group session key and a new private key are received.

This patent presents a method, apparatus and system for content protection and copyright management in digital video distribution over packet-based networks. The system consists of a distribution server and its agents. The distribution server first divides a digital video into parts and then processes them into public and control portions. The public and control portions are constructed in such a way that the public portion consists of the majority of the digital video while the control portion consists of only a small fraction of the video and other crucial information for restoring the video to its original format. The public portion is freely distributed without much restriction. In the absence of the control portion, the public portion cannot be decoded for video displaying. Thus, the control portion is delivered to an agent at a premise of authorized subscribers or viewers via a packet-based interactive secured channel at the time of restoring the full-length video content for displaying. An agent, which maintains the interactive secured channel with the distribution server, combines both public and control portions of a digital video back into its original format for displaying.
