39 results about "Secure copy" patented technology

Secure copy protocol (SCP) is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. "SCP" commonly refers to both the Secure Copy Protocol and the program itself. According to OpenSSH developers in April 2019 the scp protocol is outdated, inflexible and not readily fixed.

Circuit chip for cryptographic processing having a secure interface to an external memory

A mechanism is provided in which a secure chip for performing cryptographic and / or other functions is able to securely access a separate random access memory externally disposed with respect to a secure chip boundary. Addressing of the external memory is controlled so as to define certain regions therein which receive and store only encrypted information from the chip. Other regions of the external memory are set aside for the receipt and storage of unencrypted information. Access to the external memory is provided through a controlled interface which communicates with internal chip hardware which operates to control the flow of communication between various internal components such as cryptographic engines, data processors, internal memory of both the volatile and the nonvolatile variety and an external interface which provides the only other access to the chip. The internal chip hardware with which the external memory interface communicates is implemented as a combined ASIC and programmable hardware circuit, wherein the programmable hardware circuit is also securely configurable.

Possession of synchronized data as authentication factor in online services

A user's possession of synchronized data is used as an authentication factor. When the user requests an authentication configuration change, an authentication server requests the user to prove possession of synchronized data for that user. The user launches an authentication module on a client device hosting a local copy of the synchronized data. The authentication module creates a hash of the local copy and transmits the hash to the authorization server. Upon successfully verifying the received hash using a server copy of the synchronized data, the authentication server considers the user authorized and thus allows the user to make the authorization configuration change.

Safe output protocol for files to multiple destinations with integrity check

Protocol is provided for safe transfer of files from between nodes of a communication system. The protocol includes a handshake operation between a source (local or initiating) node sending one or more files and a remote (responding) node receiving the files to ensure that control of the file remains with the source node until the file is successfully transferred. The protocol is provided by a file transfer manager that controls the transfer process through a series of file moves that include moving the file into a directory associated with the file transfer manager, from which the file is sent and moving the file out of that directory after the remote node acknowledges a safe copy operation of the file. Files are maintained in the sending directory and under control of the source node at least for a configurable amount of time until the file is safely transferred. Files can be retrieved by the remote node after they have been transmitted for a configurable amount of time, after which they will be deleted from the local node.
