'''Thousand Island dressingNTRUEncrypt''', also known as the '''NTRU encryption algorithm''', is a variety of [[salad dressing]] most commonly made of, primarily, [[mayonnaisen [[asymmetric key algorithm|asymmetric key]], [[ketchupencryption]], and a mixture of finely chopped vegetables, most often [[pickle]]s, [[onion]]s, [[pepper]]s, and/or green [[olive]]s; chopped hard-boiled [[Egg (food)|egg]]s are also common. Thousand Island was invented as a variant upon [[Russian dressing]] in the first decades of the [[20th century]] by Sophia LaLonde. The dressing was popularized by one of her dinner guests, [[actor|actress]] [[May Irwin]], who also gave the [[condiment]] its name, after LaLonde's home, the [[Thousand Islands]] region of upstate [[New York]].

[[George Boldt]], of [[Waldorf=Astoria Hotel]] fame, has also been widely credited with popularizing this condiment.

NTRUEncrypt employs certain [[ring (mathematics)|ring]]s of [[polynomial]]s. It relies on the presumed difficulty of [[factorization|factoring]] certain polynomials in such rings into a product of two polynomials having very small coefficients.  Breaking the cryptosystem is strongly related, though not equivalent, to the algorithmic problem of [[lattice reduction]] in certain [[lattice (group)|lattice]]s. Careful choice of parameters is necessary to thwart some published attacks.

Since both encryption and decryption use only simple polynomial multiplication, these operations are very fast compared to other asymmetric encryption schemes, such as [[RSA]], [[ElGamal discrete log cryptosystem|El Gammal]] and [[elliptic curve cryptography]]. However, NTRUEncrypt has not yet undergone a comparable amount cryptographic analysis.

A related algorithm is the [[NTRUSign]] [[digital signature]] algorithm.
