RSA is one of the oldest public-key cryptography systems. It's a type of asymmetric or "public key" encryption that, like ECC, uses two private and public keys. Either key can be used to encrypt a message, while the other key is used to decrypt it. The security of the RSA algorithm...

Unlike RSA, which uses for its key space the integers in the range [0...p-1] (the field ℤp), the ECC uses the points {x, y} within the Galois field 𝔽p (where x and y are integers in the range [0...p-1]). An elliptic curve over the finite field 𝔽p consists of:...

Elliptic Curve Cryptosystems (ECC) have gained increasing acceptance in practice due to their significantly smaller bit size of the operands compared to other public-key cryptosystems. Since their com- putational complexity is often lower than in the case of RSA or discrete logarithm schemes, ECC ...
公钥密码学的比较分析 @@ Abstract—@@ In the globalization era, cryptography becomes more popular and powerful; in fact it is very important in many areas (i.e. mathematics, computer science, networks, etc). Cryptography is one of the main constituent of computer security. To meet a user's...
