摘要： A method of performing quantum key distribution across a network. The method involves a first node first agreeing a quantum key with a first intermediate node in the path. Next the intermediate node exchanges a quantum signal with the next node in the path—which is a targeted node. The intermediate node communicates with the first node using the previous established quantum key details of the quantum signal sent or received by the intermediate node. The first node then performs a key agreement step to agree a quantum key directly with the targeted node. Having established a quantum key with the current targeted node the method can be repeated but with the next node in the network path as the targeted node until a destination node is reached. The final quantum key agreed with the destination node can then be used for encrypting communication between those nodes across the network.

摘要： Methods, apparatus, programs and signals for providing communications network security. The approach is based on using established “standard” protocols, but packets (or cells or frames) are deliberately malformed by the sender, optionally according to a predetermined rule (for example by inverting a packet check digit). A filter forwards only packets identified as being invalid, optionally in accordance with the rule; packets which are valid with respect to the “standard” protocol are dropped. The filter is preferably implemented in hardware to mitigate the risk of its being compromised by a malicious attack.

摘要： Computer system protection to protect against harmful data from an external computer network (60) (e.g. the Internet) involves supplying incoming data (62) to a software checker (64) as the data enters a computer system (not shown). The checker (64) routes any suspect data (66) to an encryptor (68) which encrypts it to render it unusable and harmless. Encrypted data passes to a computer (72) in an internal network (74) and having a desktop quarantine area or sandbox (76) for suspect data. The computer (72) runs main desktop applications (78) receiving encrypted data (70) for storage and transfer, but not for use in any meaningful way because it is encrypted. Equally well applications (78) cannot be interfered with by encrypted data (70) because encryption makes this impossible. On entry into the sandbox (76), the encrypted data (70) is decrypted to usable form it then becomes accessible by software (204) suitable for use in the sandbox (76) subject to sandbox constraints.

摘要： A data content checker arrangement for protecting communication between a sensitive computer system (102) and an external computer system (104). The arrangement includes a store (108) connected to input and output sub-systems (106) and (114) and to content checkers (110) and (112) arranged in parallel. The input and output sub-systems (106) and (114) are connected to the external computer system (104) and the sensitive computer system (102) respectively. Data received from the external computer system (104) is encrypted by the input sub-system (106) using an encryption key to which the content checkers (110) and (112) have access. The content checkers (110) and (112) can therefore decrypt, read and check the data. If the data passes a content checker's checks, the checker digitally signs and stores it, decrypted, in the store (108); if the checks are not passed, the checker discards the data. The output sub-system (114) delivers data to the sensitive computer system (102) if the data has received both content checkers' digital signatures indicating acceptability.
