The Rabin cryptosystem is an asymmetric cryptographic method invented by Michael Rabin. It is based on the difficulty of factorizing large integers, similar to the RSA cryptosystem. The Rabin cryptosystem has the advantage that its security is provably as hard as the integer factorization problem12.
Key Generation
To generate keys for the Rabin cryptosystem, follow these steps:
Select two large distinct prime numbers ( p ) and ( q ) such that ( p \equiv 3 \mod 4 ) and ( q \equiv 3 \mod 4 ).
Compute ( n = p \times q ). The public key is ( n ), and the private key is the pair ( (p, q) ).
For example, if ( p = 139 ) and ( q = 191 ), then:
n = 139 * 191 = 26549Here, ( n ) is the public key, and ( (p, q) ) is the private key1.
Encryption
To encrypt a message ( M ) using the Rabin cryptosystem:
Convert the message ( M ) to a number ( m ) such that ( m < n ).
Compute the ciphertext ( c ) using the formula:
c = m^2 \mod nFor example, if the message is "R" (ASCII value 82), then:

Rabin cryptosystem - Wikipedia
Like all asymmetric cryptosystems, the Rabin system uses a key pair: a public key for encryption and a private key for decryption. The public key is published for anyone to use, while the private key remains known only to the recipient of the message.
The keys for the Rabin cryptosystem are generated as follows:
