安全漏洞中发现2 g移动数据加密标准
柏林:网络安全 研究人员在欧洲说,他们发现了一个缺陷在一个加密算法所使用的手机这可能允许攻击者窃听一些数据流量超过二十年。

在周三发表的一篇论文中,研究人员从德国、法国和挪威表示,缺陷影响GPRS或2 g移动数据标准。

虽然现在大多数手机使用4 g甚至5 g标准,GPRS在一些国家仍然是一个回退数据连接。

GEA-1算法的漏洞不可能是意外,研究人员说。相反,它可能是故意向执法部门提供创建“后门”和遵守法律限制出口的强加密工具。

“根据我们的实验分析,有六个正确的数字在德国彩票连续两次是可能拥有这些属性的关键偶然发生,“创造者Beierle鲁尔大学在德国波鸿,论文的作者说。

GEA-1算法是淘汰的手机早在2013年,但是研究人员说,他们发现电流安卓iOS和智能手机。

手机制造商和标准组织已经通知修复缺陷,他们说。

\"Security<\/figure>BERLIN: Cybersecurity<\/a> researchers<\/a> in Europe say they have discovered a flaw in an encryption algorithm<\/a> used by cellphones<\/a> that may have allowed attackers to eavesdrop on some data traffic for more than two decades.

In a paper published Wednesday, researchers from Germany, France and Norway said the flaw affects the GPRS<\/a> - or 2G - mobile data standard.

While most phones now use 4G or even 5G standards, GPRS remains a fallback for data connections in some countries.

<\/div><\/div>The vulnerability in the GEA-1 algorithm is unlikely to have been an accident, the researchers said. Instead, it was probably created intentionally to provide law enforcement agencies with a \"backdoor\" and comply with laws restricting the export of strong encryption tools.

\"According to our experimental analysis, having six correct numbers in the German lottery twice in a row is about as likely as having these properties of the key occur by chance,\" Christof Beierle of the Ruhr University Bochum in Germany, a co-author of the paper, said.

The GEA-1 algorithm was meant to be phased out from cellphones as early as 2013, but the researchers said they found it in current Android<\/a> and iOS smartphones.

Cellphone manufacturers and standards organizations have been notified to fix the flaw, they said.
