Abstract
A crypto-method of securely communicating a message; the method comprises the steps of selecting a ring R′ of bi or multi variate multinomials; generating a private key which has a multinomial f; generating a public key which has a multinomial h; encrypting by representing said message as a multinomial m in R′, selecting a random multinomial r, and computing an encrypted message; and decrypting said message using said private key.
Claims20
A crypto-method of securely communicating a message;
- the method comprising the steps of:
- selecting a ring R′ of bi or multi variate multinomials;
- generating a private key which has a multinomial f;
- generating a public key which has a multinomial h;
- encrypting by representing said message as a multinomial m in R′, selecting a random multinomial r, and computing an encrypted message;
- and
- decrypting said message using said public key.
