The objectives of secure banking application:

1. Implements class level-based access for viewing of users’ personal records.
2. Gives an idea about how transactions are secured in a bank.
3. Allows the user to encrypt his/her personal data using ECIES.
4. Maintains a record of the users’ transactions and provides security for it.

Methodology adapted: Key generation: The parameters that must be agreed upon are the elliptic curve parameters: p (prime no.) as the finite field size, a and b as the curve parameters, G as the generator point, n as the order of G, and h as the cofactor. Let P be the private key of the user. Then, the public key Q can be determined by the expression: Q=[P].G

Encryption Scheme: Algorithm used- ECIES (Elliptic Curve Integrated Encryption Scheme): INPUT: Q where Q is the public key of other party, m where m is the intended message
OUTPUT: e where e is the encrypted message, C (x,y) where C is the chosen point ALGORITHM:

1. Choose random value k [1,n-1]
2. C = [k].G
3. R = [k].Q
4. e = (Rx*m) modulo p
5. Return (e,C)

Decryption Scheme:
INPUT: e where e is the encrypted message
C where C is the chosen point
Pk where Pk is the private key of receiver
OUTPUT: d where d is the decoded message
ALGORITHM:

1. R = [Pk].C
2. d = (e*(Rx)-1) modulo p
3. Return(d)
