摘要:
A technique for securing information involves encrypting raw data into encrypted data based on an initial key. The technique further involves generating a set of key shares from the initial key via application of error correction code encoding. Each key share has a size which is independent of a size of the initial key. The technique further involves electronically storing each key share on a respective memory device of a set of memory devices (e.g., RFID tags). The initial key is reconstructable from a predetermined number of the key shares read from their respective memory devices to enable decryption of the encrypted data.
