As per the above access policy, the AES-Key-access policy allows access to the AES-key registers if the security Token is "1". Examples include a wireless keycard opening a locked door, or in the case of a customer trying to access their bank account online. It acts like an electronic key to access something. The token is used in addition to or in place of a password. The respective Security Tokens are "1" and "2".ĪES key for encryption or decryptionĪn agent with a Security Token "1" has access to AES_ENC_DEC_KEY_0 through AES_ENC_DEC_KEY_3 registers. A security token is a peripheral device used to gain access to an electronically restricted resource. Let"s assume the system has two agents: a Main-controller and an Aux-controller. If Clear (bit = "0") the action is disallowed for the corresponding agent. When set (bit = "1") bit number allows action from an agent whose identity matches that bit number. The largest security token marketplace worldwide. There could be a maximum of 32 Security Tokens that are allowed access to the AES-key registers. Search for Security Token Offerings Primary offering investments as well as secondary trading support. securities laws, more developers are beginning to seriously explore security tokens as a. Each bit in this 32-bit register is used to define a Security Token. As it becomes more obvious that all token sales are subject to U.S. The access-policy register defines which agents, using a Security Token, may access the AES-key registers. The key registers are assets, and register, AES_KEY_ACCESS_POLICY, is defined to provide necessary access controls. Subjected to federal laws for governing securities, security tokens protect investors without the involvement of a third party using smart contracts. The key is 128 bits long implemented as a set of four 32-bit registers. Consider a system with a register for storing an AES key for encryption or decryption.
