• 10:57 10:57, 29 April 2016 diff hist −26‎ Kleptography ‎ It is not always asymmetric "encryption". The discrete-log kleptogram implements a covert key exchange.

• 12:04 12:04, 28 April 2016 diff hist +14‎ Dual EC DRBG ‎ Clarified that it is a kleptographic backdoor, a very specific type of backdoor that only the attacker can use even after discovery (as opposed to a symmetric backdoor)

27 April 2016

• 11:59 11:59, 27 April 2016 diff hist +46‎ Kleptography ‎ The phrase "asymmetric backdoor" is very common. Included it in the description.

• 23:47 23:47, 20 April 2016 diff hist −262‎ Ransomware ‎ removed incorrect ransomware timeline
• 23:45 23:45, 20 April 2016 diff hist +237‎ Talk:Ransomware ‎ provided feedback to Deku-shrub
• 23:02 23:02, 20 April 2016 diff hist −262‎ Ransomware ‎ The timeline is incorrect. It starts with the flawed AIDS Trojan attack in 1989 followed by the secure ransomware attack introduced by Young-Yung in IEEE S&P 1996

17 April 2016

• 23:48 23:48, 17 April 2016 diff hist +16‎ Ransomware ‎ re-instated History section title
• 23:46 23:46, 17 April 2016 diff hist −285‎ Ransomware ‎ Timeline deleted. It is negligent since it omits the AIDS Info Trojan ransomware from 1989 (though flawed since it is symmetric crypto) and it omits the secure ransomware attack of Young-Yung IEEE S&P 1996. Perhaps fix it in an upload? Tag: section blanking
