In 1979, Rabin introduced a variation of RSA using the encryption exponent 2, which has become popular because of its speed. Its drawback is decryption to four possible messages which has led to various ideas to identify the correct plaintext. This paper provides a new Rabin-type cryptosystem based on a modulus of the form p^ {2}q.
