Can a message be signed using a private decryption key?
(2) A message can be “signed” using a privately held decryption key. Anyone can verify this signature using the corresponding publicly revealed encryption key. Signatures cannot be forged, and a signer cannot later deny the validity of his signature. This has obvious applications in “electronic mail” and “electronic funds transfer” systems.
Can a signer decipher a message?
Only he can decipher the message, since only he knows the corresponding decryption key. A message can be “signed” using a privately held decryption key. Anyone can verify this signature using the corresponding publicly revealed encryption key. Signatures cannot be forged, and a signer cannot later deny the validity of his signature.
How do you implement a public-key cryptosystem?
To implement signatures the public-key cryptosystem must be implemented with trap-door one-way permutations (i.e. have property (d)), since the decryption algo- rithm will be applied to unenciphered messages. How can user Bob send Alice a \\signed" message Min a public-key cryptosystem?
Does public re-vealing an encryption key reveal the corresponding decryption key?
A Method for Obtaining Digital Signatures and Public-Key Cryptosystems R.L. Rivest, A. Shamir, and L. Adleman Abstract An encryption method is presented with the novel property that publicly re- vealing an encryption key does not thereby reveal the corresponding decryption key. This has two important consequences: 1.
