Madrid, April 28 2004 - In just over three months, a team of mathematicians has managed to solve the latest cryptographic challenge -the RSA 576- promoted by RSA Security.
On this occasion, the challenge involved determining the two prime numbers used to generate the eight 'challenge' numbers, based on RSA 576-bit keys (174 decimal digits). In solving the challenge, the team has demonstrated that 576-bit keys are insufficient to withstand an attack launched with sufficient resources, and longer keys are recommended. Typical keys in use now are 1024-bit (310 decimal digits).
The international team that resolved the challenge was made up of mathematicians and computer experts from Germany and the Netherlands and was supported by other mathematical experts from Canada the UK and the USA. The winners receive a prize of $10,000.
