Washington is nationally recognized for its e-government solutions, K-12 educational network, and information-based economic development strategy. This year, for the third year in a row, the state was named the most ‘technically advanced’ in the Digital State survey.6 Among the state’s key achievements was the creation of a short-range, e-government planning process designed to keep pace with quick-changing Web technology. “We have committed ourselves to producing a plan which can be accepted...

Secure Electronic Transactions

Authentication is achieved through the use of digital signatures. Using a hashing algorithm, SET can sign a transaction using the sender’s private key. This produces a small message digest, which is a series of values that "sign" a message. By comparing the transaction message and the message digest, along with the sender’s public key, the authenticity of the transaction can be verified. Digital signatures are aimed at achieving the same level of trust as a written signature has in real life. This helps achieve...

and digital signature schemes. Although asymmetric encryption is very slow, it does a good job of sharing keys. Asymmetric algorithms are one way functions i.e.: it is easier to compute in one direction but complex to compute in opposite direction. Public key encryption is based on the hash values. Two main uses for public-key cryptography: • Public-key encryption: message is encrypted with the sender’s private key and can be accessed by anyone who has the corresponding public key. • Digital signatures:...

with an entity (a person or computer). These keys are mathematically related, data encrypted with one key can only be decrypted by the other key, however one key cannot be derived from the other key. The public key is distributed, optionally using a digital certificate1, and the corresponding private key is kept secret. The relation between the keys is used as follows: • Public key encryption - to send encrypted data to someone, the sender encrypts the data with the receiver’s public key, and the receiver...
