AES and RSA Encryption Explained - Boxcryptor
When doing hybrid encryption with 2048-bit RSA used to transfer a 256-bit AES key, the weak link is, from an academic point of view, the 2048-bit RSA key. According to the multiple sources considered by this well-respected website on key length , 2048-bit RSA is somwhat less secure than a block cipher with a 128-bit key, which itself is AES: Data Encryption. AES, which stands for Advanced Encryption Standard, is the most popular encryption type worldwide, and has been adopted by the U.S. government since 2002. It was first called Rijndael and it features three different key lengths: 128, 192 (this one is far less common) and 256 bits. The RSA-OAEP public-key encryption system is specified in RFC 3447. AES-CTR. This represents AES in Counter Mode, as specified in NIST SP800-38A. AES-CBC. This represents AES in Cipher Block Chaining Mode, as specified in NIST SP800-38A. AES-GCM. This represents AES in Galois/Counter Mode, as specified in NIST SP800-38D. The effective security provided by AES-128 is approximately 126-bits due to some reduced rounds attacks on AES. That is, it lost a couple of bits of theoretical security. The effective security provided by 1024-RSA is 80-bits. Breaking RSA reduces to factoring RSA or discrete logs in finite fields. The best method is the number field sieve (NFS).
Advance Encryption Standard (AES) algorithm was developed in 1998 by Joan Daemen and Vincent Rijmen, which is a symmetric key block cipher [7]. AES algorithm can support any combination of data (128 bits) and key length of 128, 192, and 256 bits. The algorithm is referred to as AES-128, AES-192, or AES-256, depending on the key length.
