Description: The given work deals with new family digital signature schemes based on solving approximate closest vector problem in NTRU-type lattices. The paper considers the cryptographic algorithm parameters and their properties, discusses the mathematical properties of the keys and algorithm parameters. The comparison of the properties of key parameters and system parameters NTRUSign and popular cryptographic system with public key RSA. Results of comparing the speed of key generation for NTRUSign and RSA is given.
