The United States announced a commitment to stop testing anti-satellite missiles that generate dangerous debris in space, a measure described Tuesday as "an important step" by the head of NASA.
The United States, the first country to make such a pledge, has encouraged other nations to follow its lead, with the goal of establishing "a new international norm for responsible behavior in space," the White House said in a statement.
"This is especially important as there is an ever-increasing number of states and non-governmental entities that rely on space services and space assets which are vulnerable to debris," it added.
The announcement comes five months after Russia destroyed one of its own satellites in a missile test that created a cloud of debris and forced the seven crew on the International Space Station to temporarily take shelter in their return ships.
Washington denounced the strike as "dangerous and irresponsible."
Russia and the United States are among the small handful of nations that possess the high-tech anti-satellite weapons known as ASATs. The missiles have also been used by China and India.

Confidentiality of communication is essential in modern societies. Traditional way of secure communication is to use encryption, which is based on the computational difficulty of certain mathematical problems such as factorizing large integers. In such schemes, the two parties first distribute a key using an asymmetric cryptographic algorithm such as RSA, which is based on the difficulty of inte
