In 1946 Government Code and Cypher School (GCCS) was renamed Government Communications Headquarters (GCHQ). In 1954 most of GCHQ's communications security responsibilities were transferred to the new London Communications Security Agency (LCSA). However GCHQ co-operated closely with the LCSA and GCHQ's L Division provided advice, cooperation and assistance in communications security matters and produced all code and cypher material for user departments. In 1969 the LCSA (by then named the Communications-Electronics Security Department) was reintegrated into GCHQ as the Communications-Electronics Security Group. |
