Project Name: RSA Processor

Description:

RSA ( Rivest Shamir Adleman )is crypthograph system that used to give a secret information and digital signature . Its security based on Integer Factorization Problem (IFP). RSA uses an asymetric key.

RSA was created by Rivest, Shamir, and Adleman in 1977.

Every user have a pair of key, public key and private key.

Public key (e) . You may choose any number for e with these requirements, 1< e <Æ(n), where Æ(n)= (p-1) (q-1) ( p and q are first-rate), gcd (e,Æ(n))=1 (gcd= greatest common divisor).

Private key (d). d=(1/e) mod(Æ(n))

Encyption (C) . C=Mª mod(n), a = e (public key), n=pq

Descryption (D) . D=C° mod(n), o = d (private key)

Specifications:

• Every user have a pair of key, public key and private key.
• Modulus n-public is integer positif k-bit which has wide from 512 until 2048 bit.
• Prime secret numbers p and q are about k/2 bit, p and q are formed use its Program Random Generate.
• Public key (e) is positif integer h-bit. Usually it’s not more than 32 bits, the possible smallest number is 3.
• Private key (d) is big number. It’s about Æ(n)-1.

Design Stages:

• Make core specifications
• Design behavioral and structural using Alliance tools
• Converting to symbolic layout
• Full verifications
• Converting to real layout
