China Passes Anti-Terrorism Law; Here's What You Need to Know

China Passes Anti-Terrorism Law; Here's What You Need to Know

December 28, 2015Swati Khandelwal
If you rely on encrypted services to keep your data private and, unfortunately, you are in China, then you are about to be worried. As of now Chinese government could snoop into the operations of technology companies as well as circumvent privacy protections in everyday gadgets. China So-called Anti-Terrorism Law Despite months of objections from major technology firms and concerns over human rights… China passed its controversial new anti-terrorism law on Sunday that requires tech companies to help decrypt information or hand over encryption keys to officials when they want to spy on someone's communication in order to counter terror operations. However, the officials swear that the law wouldn't require technology firms to install " backdoors " in their products, but it doesn't make any difference when the government mandate companies operating in China to provide encryption keys and passwords when requested. Just like recent propo

' RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis ', is an interesting paper recently published by Three Israeli Security Researchers at Tel Aviv University . They claimed that, they have successfully broken one of the most secure encryption algorithms, 4096-bit RSA , just by capturing Computer's CPU Sound while it runs decryption routines. Daniel Genkin, Adi Shamir (who co-invented RSA), and Eran Tromer , uses a side channel attack and through a process called " acoustic cryptanalysis ", they successfully extracted 4096-bit RSA key From GnuPG. " We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away, " The paper specifies some possible implementations of this attack. Some email-client softwares i.e. Enigmail can automatically decrypt incoming e-mail (for notification purposes) using GnuPG. An attacker can e-mail suitably-

It is always important to secure our system against outside threats i.e. Hackers, but it also required to protect against insider threats. The potential of damage from an Insider threat can be estimated from the example of Edward Snowden who had worked at the NSA , and had authorized access to thousands of NSA's Secret Documents, networks and systems. ' According to a recent Verizon report, insider threats account for around 14% of data breaches in 2013." Mostly, securing data involves just encryption in the cloud and keeping encryption keys out of the hands of rogue employees, but it is not enough where rogue employees should have access to encryption keys as part of their work. To prevent such risk of rogue employees misusing sensitive data, CloudFlare has released an open source encryption software " Red October ," with " two-man rule " style file encryption and decryption. " Two-man rule ", a control mechanism designed to achieve a hi
