摘要： The invention relates to a secure telecommunication method for communicating information in an e-mail between a telecommunication device of a first user and a telecommunication device of a second user. The method comprises the steps of:
• Determining by the first user whether a public key of a first asymmetric key pair for encrypted e-mail exchange is assigned to the second user,
• In response to determining, that no public key is assigned to the second user, creating a first dataset by encrypting the information by the telecommunication device of the first user using a symmetric key,
• Transferring the first dataset to the second user using the e-mail, and storing the first dataset with the telecommunication device of the second user,
• In response to receiving the first dataset by the telecommunication device of the second user, creating the first asymmetric key pair comprising the public key and a private key,
• Providing the public key of the first asymmetric key pair to a telecommunication device of the first user,
• Creating a second dataset by encrypting the symmetric key by a telecommunication device of the first user using the public key of the first asymmetric key pair,
• Transferring the second dataset to the second user,
• Decrypting the second dataset using the private key of the first asymmetric key pair by the telecommunication device of the second user, the decryption resulting in the symmetric key, and
• Retrieving the first dataset and decrypting the first dataset using the symmetric key by the telecommunication device of the second user.
