Summary
Digital signature is a mathematical technique used to validate the authenticity and integrity of digital data. It uses asymmetric cryptography to generate two keys: a public key and a private key. The public key is used to encrypt the data (hash value) and private key is used to decrypt the data. MD5 algorithm is used to generate a 128-bit hash value (message digest) which represents the digital data. This hash value is encrypted with private key and attached with the actual data. At the receiver end, the hash value is again calculated from received data and decrypted using the public key. If both hash values match, the data is authenticated. If not, the data has been modified or tampered. This technique assures the recipient that the message was created by a known sender and was not altered in transit. Only the public key can be decrypted using the private key. Hence, the recipient is assured that the message was intended for them. Digital signature has important applications in software distribution, financial transactions, electronic purchase of goods and service etc.
A magnetic signature generator can distort Earth's magnetic field to mimic vehicles.
