Abstract: A method and apparatus are disclosed for managing components of a secret key according to a secret sharing scheme. The disclosed secret sharing scheme divides a secret value, R, into n secret components (R1, R2, . . . , Rn) and one super component, S, in such a way that R can be computed from (i) any k or more R, components (k<n); or (ii) S and any one component of Rl. The secret components (R1 ,R2, . . . , Rn) are distributed to a number of authorized users. A multiple threshold secret sharing scheme assigns various users in a group into one of a number of classes. Each user class has a corresponding threshold level that indicates the number of users that must come together with their assigned components to obtain access to the shared secret. The multiple threshold scheme divides the secret into n components each having an assigned threshold level (i.e., the number of such components that are required to obtain the secret).

Abstract: A method and system for reading and identifying RFID tags of the invention is disclosed. The invention is capable of registering and storing information of a plurality of RFID tags attached to objects of the same group into a memory block of at least a specified RFID reader or RFID tag.

Then, an identification data in the passive RFID tag and /or the inventory data in the active RFID tag are read by the sink apparatus according to the above-mentioned transmission specification. Therefore, the wireless RFID only uses a signal transmission specification to route the data back to the sink apparatus.
