Title: Managing machine to machine devices
Inventor: BONE NICK
IPC: H04W8/00
Filed: 2014-09-09
Abstract: A system 600 for managing devices comprising; a memory store 605 having memory locations 610, wherein each memory location stores one or more attributes 620 associated with one or more devices; device manager 60 arranged to execute commands to take an action on the one or more attributes stored in the memory locations, and to receive from the one or more devices 120,130,140 values of the corresponding one or more attributes; and, synchroniser 630 configured to maintain synchronisation between the attributes stored in the memory store and the attributes associated with the devices. This allows devices to be managed more effectively because the device manager can execute commands on the attributes stored in the memory rather than directly on the devices, then for example, a direct and highly available communications link with each device is not required as synchronisation can take place after a break in communications is restored. Furthermore, the device manager does not need to be concerned with the particular format or configuration of each device as the memory store can be maintained in a more predictable, consistent or stable arrangement. The one or more devices can be machine to machine (M2M) devices.

Title: Block encryption/decryption apparatus and method
Inventor: YEN SUNG-MING
IPC: H04L29/06
Filed: 2014-01-29
Abstract: An encrypted message is divided into a sequence of encrypted blocks, excluding the last block in the sequence which is a reference vector. The sequence of blocks is reversed, and a first vector is added as a last block in the reversed sequence. Then, for each encrypted block, an input block is generated by an XOR operation on the encrypted block, an output block of a previous encrypted block and an encrypted block before the previous message block. The input block is decrypted using an encryption key to obtain an output block, and a message block is obtained by an XOR operation on the output block and the previous encrypted block. The last message block is compared with a second vector and is excluded when the comparison matches. The decrypted message blocks are then concatenated. The reference vector and an all-zero vector constitute the previous and next-before-previous encrypted blocks respectively when processing the first and second of the encrypted blocks.
