Abstract: Disclosed herein are system, method, and computer program product embodiments for mitigating offline decryption attacks of ciphertext. An embodiment operates by inputting plaintext into an encryptor, writing ciphertext output from the encryptor into memory, inputting the ciphertext from memory into a noise generator, outputting ciphertext from memory to an output device in response to receiving a first timing signal from a timer, and outputting noise data generated by the noise generator to the output device in response to receiving a second timing signal from the timer. The output device may be a node in a distributed ledger, in some embodiments. The distributed ledger may include a blockchain, for example. Using techniques disclosed herein, encryption may be strengthened to thwart attempts by untrusted third-party attackers to crack encryption, e.g.

Abstract: Disclosed herein are system, method, and computer program product embodiments for intrusion detection and response. An embodiment operates by receiving one or more events corresponding to one or more user actions performed during a connectivity session to a computer system. The received one or more events are compared to one or more intrusion parameters associated with the computer system. It is determined that the received one or more events correspond to the intrusion event and that the user actions are performed on a first version of the computer system. The connectivity session is switched from the first version of the computer system to a second version of the computer system responsive to the determination of the intrusion event.
