2. Overview

These release notes describe the specifications for the Java Card 3 Platform, Version 3.0.5, Classic Edition. The Java Card 3 platform consists of versions 3.0, 3.0.1, 3.0.4 and 3.0.5 of the specifications and versions 3.0.1, 3.0.2, 3.0.3, 3.0.4 and 3.0.5 of the development kit.

The Java Card platform is available in two editions, Classic and Connected. This Version 3.0.5 release of the specifications is for the Classic Edition; the Connected Edition specifications are not included in this release.

This release of the Classic Edition specifications is based on an evolution of Version 3.0.4 of the Classic Edition specifications, and targets more resource-constrained devices that support applet-based applications. This release introduces more security features/updates to protect against attacks and better alignment with other industry standards. Also included are bug fixes and clarifications against the Java Card Classic Edition specifications, Version 3.0.4, and new security algorithms.

• Diffie-Hellman modular exponentiation
• New interfaces - DHKey, DHPrivateKey, and DHPublicKey. These interfaces support Diffie-Hellman modular exponentiation.
• Domain Data Conservation
• Added constants ALG_TYPE_DH_PARAMETERS, ALG_TYPE_DSA_PARAMETERS, ALG_TYPE_EC_F2M_PARAMETERS, ALG_TYPE_EC_FP_PARAMETERS and method buildKeyWithSharedDomain(byte algorithmicKeyType, byte keyMemoryType, Key domainParameters, boolean keyEncryption) to class javacard.security.KeyBuilder to support Domain Data Conservation for Diffie-Hellman, Elliptic Curve and DSA keys
• OneShot inner classes
• Added classes javacard.security.Signature.OneShot, javacard.security.RandomData.OneShot, javacard.security.InitializedMessageDigest.OneShot and javacard.security.MessageDigest.OneShot to support efficient one-shot, signing, verification, random number generation and hashing operations.
