Latest Patents

Cramer's latest patent is a practical non-malleable public-key cryptosystem. This innovative scheme improves the security of encrypted data by utilizing a public-key cryptosystem that can resist adaptive attacks. The system is designed to ensure that no information about the secret key is leaked. It generates an extended private key and public key, allowing a message, referred to as plaintext, to be encrypted into a ciphertext using the public key. Only the recipient with the correct private key can decrypt the ciphertext. Before decryption, a verification process of the ciphertext is conducted to confirm its legitimacy. This verification ensures that the ciphertext is either decrypted back to plaintext or rejected if it is deemed illegitimate or invalid.
