摘要： A system may include at least one hardware processor implementing a verification unit configured to: receive a set of data from a first computer network; transmit an encrypted version of the set of data to a destination within a second computer network; receive a signature associated with the set of data from the first computer network; verify that the signature is indicative of the set of data being from a known source; and in response to verification of the signature, transmit a decryption key associated with the encrypted version of the set of data to the destination, wherein the destination is configured to decrypt the set of data with the decryption key.

摘要： A first computer network 1, the computer network which is transmitting data, and a second computer network 2, the computer network which is receiving the data. The first computer network comprises a verification unit 7, which comprises a key generator 9, an encryption engine 10, a verification hasher 11, a signature verifier 12. The encryption engine 10 encrypts the data stream using an encryption key. As each part of the data stream is encrypted it is transmitted to the second computer network 2. The signature verifier 12 uses a decryption key to decrypt a signature for the set of data, and compares the decrypted signature to the hash value calculated by the verification hasher 11. The decrypted signature matching the hash value means the correct private key was used to create the signature and the set of data has not been modified since the signature was created, and so the signature is valid. If the signature verifier 12 verifies the signature by determining it is valid, the key generator 9 then transmits the encryption key to the second computer network 2.

摘要： A computer-implemented method of mitigating the effect of a security threat present in a computer file of a known type. The method involves modifying the file to mitigate unsafe behaviour when the file is interpreted in accordance with the known type and/or in accordance with one or more different file types, and subsequently checking the modified file to ensure that it exhibits a known safe behaviour when interpreted according to the one or more different file types. The modified file may be checked to ensure it exhibits known safe behaviour when interpreted according to the one or more different file types. There may be two or more independent checks each according to one of the one or more different file types. The independent checks may be done in parallel. The step of modifying may include adding a damper to the file.

摘要： A method of transmitting a graph structure from a first computer to a second computer in which a plurality of messages containing the data of a node of the structure are sent from the first computer to the second computer. The second computer constructs nodes in its memory in response to the messages received in such a way that part of a node can be distinguished from the remainder of the node. The messages may include a reference to a previously sent node, or to a child pointer which must be updated with the address of a newly created node. These references are validated by determining if they refer to an inappropriate part of a node.

摘要： A data structure is transmitted from a first computer to a second computer by transmitting a plurality of messages from the first computer to the second computer. Each message contains data of a node of the structure and one or more references to child pointer locations in previously transmitted nodes. The data of each transmitted node is stored in the second computer, and the location of each node is stored in a table of addresses and the or each reference includes an index into the table of addresses. The first computer may then use indexes into the table to identify which nodes need updating, and thus avoid the need for the first computer to know how the second computer is allocating nodes in memory. The or each reference may include an index into an array of child pointers belonging to a node, may include the sequence number of the parent node of the node being transmitted and may also include the index into the parent nodes children to the pointer to the node being transmitted.

摘要： Apparatus for connecting two or more computer networks having two or more network interface machines 201, 202, 203 each arranged to be connected to a respective computer network with a bidirectional communications link 105, 106, 107 enabling the network interface machine to receive data from and transmit data to the respective computer network. The network interface machines are connected together with at least one content checker 210, 211 to enable data to be transmitted from one network interface machine to another, and arranged such that data transmitted from one network interface machine to another network interface machine must pass via a content checker. Each network interface machine is arranged to transmit flow control data to another network interface machine to regulate transmission of data between the two network interface machines. The network interface machines may be connected to the content checkers only by unidirectional communications links 219, 220. In further embodiments content checkers of differing characteristics may be used in series (Figure 3) or may be used in a ring-like formation (Figure 5). The content checking may be checking for confidential/sensitive information such as being passed between differing security level networks or checking for damaging/malicious content. The interface machines act as a proxy for their respective networks. The flow control information may include ACK/NACK type signalling, ready to receive indications or requests for further data transmission.
