Abstract (en)
[origin: WO2009103364A1] The invention relates to a method for encrypting and decrypting data of any type, the data being encrypted or decrypted with a random key to secure the integrity and/or authenticity of the data and/or to keep the data contents secret. At least one permutation date, a key control date and a random number are generated at the location of encryption. Random keys are determined from at least one separate random reference date and a random number. Plain text data are bit-permuted depending on the permutation data and the random keys and are encrypted and/or packet-permuted. The permutation data, key data and random data are added to the encrypted data in the form of relative data. The data added are used at the location of encryption to determine all data required for decryption and the encrypted data are decrypted.
