    • An enhanced encryption keypad (100) capable of preventing illegal disassembly for an automated teller machine comprises a key panel (101) and a main control board (102). A removal detection protection circuit is disposed inside a main chip of the main control board (102), and at least one pin of the removal detection protection circuit is guided out from a surface (1021) of a side of the main control board (102) near the key panel to form a removal detection point (1022). The removal detection point (1022) has two opened signal contact points. The two opened signal contact points are conducted by a conductive adhesive (103) to activate the removal detection protection circuit. A conductive protection ring (1023) isolated from the removal detection point is disposed at the periphery of the removal detection point. The conductive protection ring (1023) is connected to the removal detection protection circuit inside the main control chip. A protection circle (1024) is disposed at the periphery of the conductive protection ring and the corresponding conductive adhesive. The present application effectively protects the encryption keypad from illegal attacks on the removal detection point from the side.

    • An pry-proof encrypted keyboard. The encrypted keyboard comprises a keyboard panel (1), a lining board (2) assembled under the keyboard panel (1), a waterproof silicon rubber (4) and a main control panel (5). Convex rib circles (22) are provided on the circumference of the surface of the lining board (2) attached with the waterproof silicon rubber (4). The waterproof silicon rubber is extruded by the lining board (2) when the encrypted keyboard is assembled, and the thickness of corresponding waterproof silicon rubber (4) extruded by the convex rib circles (22) is less than 0.2 MM. The metallic lining board (2) can efficiently prevent fusion attack from the lateral face of the encrypted keyboard, meanwhile two convex rib circles (22) are added on the circumference of the surface of the lining board attached with the water silicon rubber (4), so that the thickness of the waterproof silicon rubber (4) at the grooves (41) is less than 0.2 MM, which is the diameter of the known thinnest needle, thus the attackers could not easily breakthrough the lining board (2) or the waterproof silicon rubber (4) to reach the inside of the encrypted keyboard, as a result illegally leading the wire out from the inside of the encrypted keyboard is efficiently prevented, thus the information of the keyboard is efficiently protected, and the security performance is improved.
    • 防撬密码键盘。 加密键盘包括键盘面板(1),组装在键盘面板(1)下方的衬板(2),防水硅橡胶(4)和主控制面板(5)。 在安装有防水硅橡胶(4)的衬板(2)的表面的圆周上设置凸肋(22)。 当加密键盘组装时,防水硅橡胶由衬板(2)挤出,由凸肋圆(22)挤出的相应的防水硅橡胶(4)的厚度小于0.2MM。 金属衬板(2)可以有效地防止加密键盘的侧面发生熔融攻击,同时在附着水硅橡胶(4)的衬板表面的圆周上添加两个凸肋圈(22) ,使得凹槽(41)处的防水硅橡胶(4)的厚度小于0.2MM,这是已知最薄针的直径,因此攻击者不能轻易地穿过衬板(2)或 防水硅橡胶(4)到达加密键盘的内部,从而非法地从加密键盘的内部引出导线,从而有效地防止了键盘的信息被有效地保护,并提高了安全性能 。
