However , strong primes do not protect against modulus factorisation using newer algorithms such as Lenstra elliptic curve factorization and Number Field Sieve algorithm .
For this reason , strong primes are required by the ANSI X9. 31 standard for use in generating RSA keys for digital signatures .
