Patent number: 9148419Abstract: Methods, systems and apparatuses for an operator provisioning a trustworthy workspace to a subscriber are disclosed. One method includes providing the subscriber with the trustworthy workspace, where in the trustworthy workspace comprises a virtualized content repository with trustworthy workflows for storing, sharing and processing a digital content across a plurality of repositories. The method further includes allowing the subscriber authority to sub-provision the trustworthy workspace to one or more authorized parties, wherein only the one or more authorized parties can view or modify at least a portion of the digital content.Type: GrantFiled: October 14, 2014Date of Patent: September 29, 2015Assignee: PivotCloud, Inc.Inventors: Roy Peter D'Souza, Santosh S.

Patent number: 8730840Abstract: In a system comprising a first fabric and a plurality of devices coupled to the fabric by Fiber Channel connections, the devices are logically grouped to form configurations and zones. A configuration includes at least one zone, and each zone includes at least one device as a member of the zone. Communications between the devices is restricted according to the configuration currently in effect. For example, one device may be permitted to communicate with another device only if they are members of a common zone.Type: GrantFiled: August 31, 2012Date of Patent: May 20, 2014Assignee: Polycom, Inc.Inventors: David Banks, Kumar Malavalli, Paul Ramsay, Kha Sin Teow, Jieming Zhu

Publication number: 20130212388Abstract: Methods, systems and apparatuses for providing trustworthy workflow across trust boundaries are disclosed. One method includes a curator generating a first public key (PKC1) and a second public key (PKC2), publishing the first public key (PKC1) and the second public key (PKC2), and generating a first proxy re-encryption key (RKC1-C2) and a second proxy re-encryption key (RKC2-B). Further, a first party encrypts data having a key k, wherein k is encrypted according to the first public key (PKC1). A custodian proxy re-encrypts k from the first public key (PKC1) to the second public key (PKC2) using the first proxy re-encryption key (RK C1-C2), and the custodian proxy re-encrypts k from the second public key (PKC2) to a public key (PKB) of the second party B using the second proxy re-encryption key (RKC2-B). The second party B receiving the data and decrypting the data with the key k.Type: ApplicationFiled: September 13, 2012Publication date: August 15, 2013Applicant: ALEPHCLOUD SYSTEMS, INC.Inventors: Roy Peter D'Souza, Jieming Zhu

Patent number: 7447198Abstract: In a communication network system having a multi-switch Fiber Channel fabric, adjacent switches are communicatively coupled together by a plurality of links. The links are selectively determined to join a trunked group for enabling frames received at one switch to be routed over the links in the trunked group to the adjacent switch in an evenly distributed manner. In one embodiment, a link within the trunked group is coupled to a pair of ports residing on adjacent switches each having a designated trunking master port. The traffic load at one switch is routed through the trunking master port which distributes the load across multiple links and guarantees that the load is received at the adjacent switch with “in-order” delivery.Type: GrantFiled: June 1, 2001Date of Patent: November 4, 2008Assignee: Brocade Communications Systems, Inc.Inventors: David C. Banks, Kreg A. Martin, Shunjia Yu, Jieming Zhu, Kevan K. Kwong

Patent number: 7366194Abstract: The present invention provides a system and a method for filtering a plurality of frames sent between devices coupled to a fabric by Fiber Channel connections. Frames are reviewed against a set of individual frame filters. Each frame filter is associated with an action, and actions selected by filter matches are prioritized. Groups of devices are “zoned” together and frame filtering ensures that restrictions placed upon communications between devices within the same zone are enforced. Zone group filtering is also used to prevent devices not within the same zone from communicating. Zoning may also be used to create LUN-level zones, protocol zones, and access control zones. In addition, individual frame filters may be created that reference selected portions of frame header or frame payload fields.Type: GrantFiled: April 17, 2002Date of Patent: April 29, 2008Assignee: Brocade Communications Systems, Inc.Inventors: Shunjia Yu, David C.
