Method and apparatus for encrypting data

摘要

A method for encrypting data comprising dividing a first data set into a second data set and a third data set; deriving a first value using the second data set as an input into a polynomial equation; deriving a second value using the third data set as an input into the polynomial equation; deriving a first encryption key associated with a first party 30; deriving a second encryption key associated with a second party 40; encrypting the first value with the first encryption key; encrypting the second value with the second encryption key. The method may further comprise providing the first and second encrypted values to a third party 70 for decryption and recovery of the first data set. The first and second parties 30, 40 may be a first 80 and second 90 trust authority respectively.
