Encryption process for simple modular operation using Montgomery method |
摘要 |
The process is performed on the Pfield as defined by the Montgomery method where Pfield (A,B)n = A asterisk B asterisk I mod n, where I is a determinable error. The process performs a double shift on the least significant bits of words A and N. This makes it unnecessary to perform addition on later cells of significant size.
