Abstract

A method is set forth for encrypting and decrypting a message, including: selecting a plurality of integers and a plurality of vectors, and deriving therefrom a public key that includes a collection of vectors and a private key; selecting a message, in the form of a vector; selecting a vector of random weights; deriving a preliminary encrypted message, in the form of a vector, as a function of the selected message, the public key, and the random weights; evaluating the preliminary encrypted message to derive a normalizing value; combining the preliminary encrypted message and the normalizing value, to obtain a security-enhanced encrypted message; and decrypting the security-enhanced encrypted message using the private key, to recover the selected message.
