Patent number: 12132840Abstract: The invention provides a method and system for authenticating a plaintext message at a sender computing device and verifying the integrity and authenticity of the plaintext message at a receiver computing device. Firstly, the method includes prepending a random string to the plaintext message and then generating a ciphertext corresponding to the plaintext message by encrypting the plaintext message prepended with the random string using an encryption algorithm. The method also includes the step of generating a compressed image of the plaintext message and generates an authentication tag from the compressed image of the plaintext message and the random string. Thereafter, the method transmits both the ciphertext and the authentication tag generated at the sender computing device to the receiver computing device. The receiver computing device, on receiving the ciphertext and the authentication tag corresponding to the plaintext message, verifies the integrity and authenticity of the plaintext message.Type: GrantFiled: June 21, 2016Date of Patent: October 29, 2024Assignee: The King Abdulaziz City for Science and TechnologyInventor: Basel Saleh Alomair
