Claim Text:
1. A method comprising: obtaining a first message; and encrypting the first message to produce a ciphertext; wherein encrypting the first message comprises mapping a first key to a first seed, mapping the first message to a second seed, determining an offset between the first and second seeds, and generating the ciphertext based on the determined offset; wherein the first message is encrypted such that decryption of the ciphertext utilizing the first key yields the first message and decryption of the ciphertext utilizing a second key different than the first key yields a second message that is distinct from the first message but shares one or more designated characteristics with the first message in a manner that prevents an attacker from determining solely from the second message if decryption of the ciphertext has been successful or unsuccessful; and wherein the obtaining and encrypting are performed by at least one processing device comprising a processor coupled to a memory.
