The RSA Factoring Challenge was a challenge put forward by RSA Laboratories on March 18, 1991 [1] to encourage research into computational number theory and the practical difficulty of factoring large integers and cracking RSA keys used in cryptography. They published a list of semiprimes (numbers with exactly two prime factors) known as the ...
The following table is a list of countries by number of public holidays excluding non-regular special holidays. Nepal has the highest number of public holidays in the world with 35 annually. Also, Nepal has 6 day working schedule in a week. But in 2023 India has 365 holidays which 17 Gazetted holidays and more than 340 restricted holidays.
27 December 2016 was declared a holiday by president Jacob Zuma following a request by the Federation of Unions of South Africa (FEDUSA). [23] The request by FEDUSA was motivated by the fact this year, workers in the country will only have 11 public holidays instead of 12 due to fact that 25 December (Christmas Day) falls on a Sunday.
RSA numbers. In mathematics, the RSA numbers are a set of large semiprimes (numbers with exactly two prime factors) that were part of the RSA Factoring Challenge. The challenge was to find the prime factors of each number. It was created by RSA Laboratories in March 1991 to encourage research into computational number theory and the practical ...
The presumed difficulty of this problem is important for the algorithms used in cryptography such as RSA public-key encryption and the RSA digital signature. Many areas of mathematics and computer science have been brought to bear on the problem, including elliptic curves, algebraic number theory, and quantum computing.
In computational complexity theory, a computational hardness assumption is the hypothesis that a particular problem cannot be solved efficiently (where efficiently typically means "in polynomial time "). It is not known how to prove (unconditional) hardness for essentially any useful problem. Instead, computer scientists rely on reductions to ...
RSA ( Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission. The initialism "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977. An equivalent system was developed secretly in 1973 at Government Communications ...
Several federal holidays are widely observed by private businesses with paid time off. These include New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Businesses often close or grant paid time off for New Year's Eve, Christmas Eve, and the Day after Thanksgiving, but none of these are federal holidays ...
