The ECC (Elliptic Curve Cryptography) algorithm was originally independently suggested by Neal Koblitz (University of Washington), and Victor S. Miller (IBM) in 1985. Although the ECC algorithm was proposed for cryptography in 1985, it has had a slow start and it took nearly twenty years, until 2004 and 2005, for the scheme to gain wide acceptance. ECC (Elliptic Curve Cryptography) is a relatively new algorithm that creates encryption keys based on using points on a curve to define the public and private keys.

Nov 02, 2016 I this episode we dive into the development of the public key. In just 44 lines of code, with no special functions or imports, we produce the elliptic curve public key for use in Bitcoin. Jun 08, 2014  In just 44 lines of code, with no special functions or imports, we produce the elliptic curve public key for use in Bitcoin. Better still, we walk you through it line by line, constant by constant. Feb 22, 2012 The fig 3 show are simple elliptic curve. Key Generation. Key generation is an important part where we have to generate both public key and private key. The sender will be encrypting the message with receiver’s public key and the receiver will decrypt its private key. Now, we have to select a number ‘d’ within the range of ‘n’.

• Elliptic Curve Digital Signature Algorithm or ECDSA is a cryptographic algorithm used by Bitcoin to ensure that funds can only be spent by their rightful owners. This tool is capable of generating key.

Key Benefits of ECC

Elliptic Curve Cryptography Explained

ECC key is very helpful for the current generation as more people are moving to the Smartphone. As the utilization of Smartphone extends to grow, there is an emerging need for a more flexible encryption for business to meet with increasing security requirements.

Stronger Keys

ECC stands for Elliptic Curve Cryptography is the latest encryption method offers stronger security. If we compare to the RSA and DSA algorithms, then 256-bit ECC is equal to 3072-bit RSA key. The reason behind keeping short key is the use of less computational power, fast and secure connection, ideal for Smartphone and tablet too.

The US government and the National Security Agency have certified ECC encryption method. The mathematical problem of the ECC algorithm, It is harder to break for hackers compare to RSA and DSA, which means the ECC algorithm ensures web site and infrastructure safety than traditional methods in a more secure manner.

Shorter Key Size

The elliptic curve cryptography (ECC) certificates allow key size to remain small while providing a higher level of security. ECC certificates key creation method is entirely different from previous algorithms, while relying on the use of a public key for encryption and a private key for decryption. By starting small and with a slow growth potential, ECC has longer potential lifespan. Elliptic curves are likely to be the next generation of cryptographic algorithms, and we are seeing the beginning of their use now.

If we examine the above table, there is a considerable growth in DSA and RSA key than ECC key size. A longer key requires more space, more bandwidth, and additional processor power. Even, it will take a time to generate a key, encrypt data, and decrypt the data.

Why Elliptic Curve Cryptography is Required?

Encryption experts are pressed to find ever more effective methods, measured in security and performance, because the threats presented by hackers are ever greater – partly because the hackers themselves become more sophisticated in their attacks, and also because the fallout from an attack gets ever more dangerous as our use of data grows. It creates an urgency of new algorithms with a goal to provide a higher level of security by having keys that are more difficult to break, while offering better performance across the network and while working with large data sets.

Elliptic Curve Cryptography Generate Public Key From Private Key

Several factors are contributing to its increasing popularity. First of all, the security of 1024-bit encryption is degrading, due to faster computing and a better understanding and analysis of encryption methods. While brute force is still unlikely to crack 1024-bit encryption, other approaches, including highly intensive parallel computing in distributed computing arrays, are resulting in more sophisticated attacks. These attacks have reduced the effectiveness of this level of security. Even 2048-bit encryption is estimated by the RSA Security to be effective only until 2030.

• Web standards: Business owner has to mull over web server standards. Many web servers running on a single domain name can handle RSA, DSA, and ECC configuration. On the other side, few web servers do not have the ability to handle multiple algorithms and can utilize a single certificate on a single web server.
• Authentication speed: RSA, DSA, and ECC have diverse velocity for verification and authentication. RSA is a rapid algorithm in terms of client authentication while ECC is faster in terms of server authentication. Signature verification is rapidly in case of RSA key comparing to ECC key. There are transaction types, the processing power of the device; storage capacity, bandwidth, and consumption of power also influence the algorithm selection.
• Customer’s identity: Many government entities have started to accept DSA and ECC. They required for government subcontracts, government branches for their internal exchange of communication.

The number of connections plays a vital role in selecting algorithm standard. ECC can handle more connections at the same time compare to RSA algorithm. An Organization has to maintain the balance between security, user experience, and IT infrastructure cost involved in network process.

Definition

Provides a Cryptography Next Generation (CNG) implementation of the Elliptic Curve Diffie-Hellman (ECDH) algorithm. This class is used to perform cryptographic operations.

Examples

The following example shows how to use the ECDiffieHellmanCng class to establish a key exchange and how to use that key to encrypt a message that can be sent over a public channel and decrypted by the receiver.

Remarks

The ECDiffieHellmanCng class enables two parties to exchange private key material even if they are communicating through a public channel. Both parties can calculate the same secret value, which is referred to as the secret agreement in the managed Diffie-Hellman classes. The secret agreement can then be used for a variety of purposes, including as a symmetric key. However, instead of exposing the secret agreement directly, the ECDiffieHellmanCng class does some post-processing on the agreement before providing the value. This post processing is referred to as the key derivation function (KDF); you can select which KDF you want to use and set its parameters through a set of properties on the instance of the Diffie-Hellman object.

The result of passing the secret agreement through the key derivation function is a byte array that may be used as key material for your application. The number of bytes of key material generated is dependent on the key derivation function; for example, SHA-256 will generate 256 bits of key material, whereas SHA-512 will generate 512 bits of key material.The basic flow of an ECDH key exchange is as follows:

1. Alice and Bob create a key pair to use for the Diffie-Hellman key exchange operation

2. Alice and Bob configure the KDF using parameters the agree on.

3. Alice sends Bob her public key.

4. Bob sends Alice his public key.

5. Alice and Bob use each other's public keys to generate the secret agreement, and apply the KDF to the secret agreement to generate key material.
