FIELD: information technology.SUBSTANCE: method involves using a first set from one or more input encryption parameters for decrypting data in a received protocol data unit, wherein encrypted data were encrypted using a second set from one or more input encryption parameters; comparing the value of at least part of the decrypted data with an expected value; detecting, using a decryption control scheme, an encryption error if the value of at least part of the decrypted data does not match the expected value; and initiating an encryption resynchronisation procedure in response to the determination that there has been an encryption error, in order to resynchronise at least one input encryption parameter from the first set with at least one input encryption parameter from the second set.EFFECT: solving problems of detecting and correcting encryption errors in a network not designed to support an encryption error correction procedure.14 cl, 6 dwg |
