Public Key Crypto: Low e Attacks on RSA. REDO - UMD

WebJun 27, 2013 · Abstract: RSA cryptosystem is the most popular public key cryptosystem which provides both secrecy and digital signatures. Due to RSA's popularity, many attacks on it have been developed. In this paper, we consider experimentally attacks on low private exponent RSA and find that: (i) lattice attack using Gauss lattice reduction algorithm is … WebMoral: avoid decryption exponents less than . (Since n is a 1024-bit integer, this means d must be at least 257 bits.) Small encryption exponent attack. This was shown above, with Bob sending e of the same messages to e friends. But in fact small encryption exponents are insecure even if the message is padded to make it look different. clsu hectares
