New record in the area of prime number decomposition of cryptographically important numbers
An international team of scientistshas obtained the prime factors of the RSA challenge number RSA-768, using the Number Field Sieve. The calculation took less than 2000 core years on modern CPUs. Extrapolating the trend from previous records in this area (512-bit in 1999, 663-bit in 2005, and the current 768-bit in 2009), it is reasonable to expect that 1024-bit keys will exhibit a similar degree of vulnerability within the next decade.
