    摘要： A method for executing applications on an untrusted device includes selecting one or more applications as sensitive applications. One or more instruction sequences of the said one or more sensitive applications are modified by an external dongle. The one or more sensitive applications are executed on the untrusted device according to the modified instruction sequences. Whether correct execution of the instructions of the said modified instruction sequences has Occurred is checked by the external dongle.

    摘要： A method for verifying positions of a plurality of monitoring devices includes selecting a second monitoring device by a first monitoring device. A first number of monitoring devices out of the plurality of monitoring devices is supervised, the plurality of monitoring devices being positioned such that each monitoring device of the plurality of monitoring devices can be monitored by at least one other monitoring device of the plurality of monitoring devices. Correct positions of the plurality of monitoring devices have been determined and stored prior to verification, and security information for secure communication has been exchanged between two of the plurality of monitoring devices for all of the plurality of monitoring devices.

    摘要： A method for accessing a device by a user connected to the device and to at least two servers in different networks includes collaboratively generating parts of an authentication ticket on the at least two servers, collaboratively generating parts of a user session key and encrypting a combined user session key, authenticating with the authentication ticket at a distributed ticket granting server by collaboratively decrypting user request information using the combined user session key and comparing its content with the authentication ticket, collaboratively generating an encrypted user-to-device ticket and an encrypted user-to-device session key, and accessing the device by the user using the encrypted user-to-device ticket and the user-to-device session key.

    摘要： A method of providing a transaction forwarding service in a blockchain includes executing a smart contract in the blockchain so as to determine whether a respective full node is eligible to execute the smart contract. The smart contract specifies eligible full nodes, a filter of a respective light client and a reward for executing the smart contract. The respective full node forwards data relating to a transaction that matches the filter of the respective light client to the respective light client with a proof that the transaction is included in the blockchain. The respective full node receives a signed acknowledgement from the respective light client verifying the transaction. Then, the respective full node claims the reward using the acknowledgement.

    摘要： A method for secure cloud storage of user data includes deriving, using content of the user data and a secret key stored by a server, an encryption key, encrypting, using the derived encryption key, the user data to provide encrypted user data, applying an all-or-nothing transform on the encrypted user data to produce blocks of transformed encrypted user data, partitioning the blocks of transformed encrypted user data to data partitions, creating, for each of the data partitions, an authenticator, and performing data deduplication on the transformed encrypted user data.
