 Dec2 awarded Notable Question Jun11 awarded Popular Question Aug14 accepted Common modulus attack on RSA when the 2 public exponents differ by a single bit Aug14 comment Common modulus attack on RSA when the 2 public exponents differ by a single bit thanks! i am clear now! Aug14 comment Common modulus attack on RSA when the 2 public exponents differ by a single bit still didn't get it, say e and e2 can be divided by n, how come e-e2 can be divided by n as well? i can't see the relationship between e-e2 and n... Aug14 comment Common modulus attack on RSA when the 2 public exponents differ by a single bit sorry for my stupid question, why n can be divided by e-e2?, is that a property? or can it prove? Aug14 comment Common modulus attack on RSA when the 2 public exponents differ by a single bit Thanks for your answer , may i know why gcd(e,e2) = gcd(e,e-e2) Aug14 asked Common modulus attack on RSA when the 2 public exponents differ by a single bit Aug4 awarded Scholar Aug4 awarded Supporter Aug4 accepted How to jusify {e,n} is a valid RSA public key? Aug4 comment How to jusify {e,n} is a valid RSA public key? that's cool! spending some time, finally understand what do you mean, may i have one more follow up, why Euler toient function of N, must be even number? Aug2 awarded Student Aug2 comment How to jusify {e,n} is a valid RSA public key? thx for your answer. i didn't get what this mean "e is relatively prime to ϕ(N)" can you illustrate by a simple example?
