Abstract

The present invention relates to the field of computer data encrypting and decrypting, especially for mobile equipments like PDA, mobile phones, smart cards and the like, which need a good trade-off between computing speed, power consumption and security strength. The invention provides an encrypting/decrypting method implementing simple data operation. This method is based on generating a pseudo-random sequence through a function of the Collatz (or Syracuse) family from a starting number used as a secret key. Binary words of a secret length, extracted from the plain data, are encrypted into a sequence of encrypted numbers representing the offsets of these words whithin the binary form of the pseudo-random sequence.
