The invention provides a method and system for generating a message authentication code (MAC) for authenticating a message and for verifying the integrity and authenticity of the message. The method for generating the MAC for authenticating the message includes the step of compressing the message to generate a fixed-size residue of the message. The fixed-size residue of the message is computed from the message modulo a divisor. The method, then, multiplies the fixed-size residue of the message by an authentication key. Thereafter, the method computes an authentication tag for the message by encrypting the fixed-size residue of the message utilizing a semantically secure encryption algorithm. The method, then, transmits both the message and the authentication tag of the message from a sender computing device to a receiver computing device where the method verifies the integrity and authenticity of the message using the authentication key.
