Two incarnations of the IES are standardized: Discrete Logarithm Integrated Encryption Scheme (DLIES) and Elliptic Curve Integrated Encryption Scheme (ECIES), which is also known as the Elliptic Curve Augmented Encryption Scheme or simply the Elliptic Curve Encryption Scheme. These two incarnations are identical up to the change of an underlying group and so to be concrete we concentrate on the latter Information about the decryption is required to determine the curve used. The key length can be determined from the public key that is part of the ECIES ciphertext message. From that it should be possible to iterate over all known standardized curves with that same size and find the curve by performing the decryption I am trying to use ECIES for encryption and decryption. This is what I have done: generated ECC key pair. generated CSR. Generated X509 certificate, signed by intermediate CA. Server side, I need to use this certificate to encrypt data. So I have extracted PublicKey (which is showing BCECPublicKey format) from certificate Use ECDH to exchange an AES session key; Notice that the sender public key is generated every time when ecies.encrypt is invoked, thus, the AES session key varies. We are using HKDF-SHA256 instead of SHA256 to derive the AES keys. Use this AES session key to encrypt/decrypt the data under AES-256-GCM The Elliptic Curve Integrated Encryption Scheme (ECIES) mechanism, denoted CKM_ECIES, performs single-part encryption and decryption operations. The operations performed are as described in ANSI X9.63-2001. This mechanism has a parameter, a CK_ECIES_PARAMS structure. This structure is defined as follows

public byte [] decrypt (byte [] cipherText) throws Exception {// get ECIES cipher objects: Cipher bcipher = Cipher. getInstance( ECIES ); // generate derivation and encoding vectors: byte [] d = new byte [] { 1, 2, 3, 4, 5, 6, 7, 8}; byte [] e = new byte [] { 8, 7, 6, 5, 4, 3, 2, 1}; IESParameterSpec param = new IESParameterSpec (d, e, 256) Elliptic Curve Integrated Encryption Scheme, or ECIES, is a hybrid encryption system proposed by Victor Shoup in 2001.ECIES has been standardized in ANSI X9.63, IEEE 1363a, ISO/IEC 18033-2, and SECG SEC-1. Shoup's submission can be found at A Proposal for an ISO Standard for Public Key Encryption (v2.1).. ECIES combines a Key Encapsulation Mechanism (KEM) with a Data Encapsulation Mechanism (DEM)

- There is no encrypt or decrypt operation! ECIES. ECC encrypt is not a primitive operation. Instead we can use ECDH (Elliptic Curve Diffie Helman) to generate a shared secret, and use this as a secret key. This is called ECIES (Elliptic Curve Integrated Encryption Scheme).

- For one thing, ECIES basically does an ECDH exchange with the receiver's public key and a random ephemeral private key to derive a shared secret, which is then used as the key for AES-encrypting the message. The message is sent over to the recipient along with the AES parameters (IV, MAC) and the ephemeral public key. The recipient can use that public key along with their private key in ECDH, get the same shared secret, and do another round of AES with the given parameters to.

Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.ECC allows smaller keys compared to non-EC cryptography (based on plain Galois fields) to provide equivalent security.. Elliptic curves are applicable for key agreement, digital signatures, pseudo-random generators and other tasks The { 0x00, 0x00, 0x00, 0x01 } and { 0x00, 0x00, 0x00, 0x02 } arrays are being created every time in encrypt and decrypt. They could both be static readonly. Also, how might the API change if different KDF functions.

ECIES (Elliptic Curve Integrated Encryption Scheme) is a standardised, hybrid encryption scheme for the encryption of data using ECC (Elliptic Curve Cryptography). It uses a KDF (key derivation function) to deriving a separate MAC key and symmetric encryption key from a ECDH shared secret. A good summary can be found here The functionality comprises, ECC private key management (generation, derivation, deletion), ECDSA signature generation, ECIES encryption and decryption, storage of generic data, as well as getting information about the device. Complete software occupies half of the available flash space, leaving 1MB for user data When you decrypt an invalid ciphertext with ECIES, the DecodingResult returned by Decrypt() should have isValidCoding == false. Is this not the case? V is a temporary public key created for the message, and is needed to decrypt. T can be omitted if you do not care about the security properties that it provides, but to do this you'll need to create a dummy MAC class with a 0 MAC tag size and.
