An extension of the El Gamal encryption algorithm
Stelian Flonta, Liviu Cristian Miclea · 2008
The encryption algorithms generally allow the encryption of a whom message by one person, we call Alice, and the decryption of the message encrypted by another person, with the generic name Bob. The algorithm presented in this paper work , is based on the following scheme: Alice is encrypting a message which she is simultaneously sending to the persons Bob1, Bob2, ..., Bob2n+1. The 2n+1 persons (Bob1, Bob2, ..., Bob2n+1 ) will be able to decrypt the message received from Alice only if they are together, separately this operation being impossible for them.
